The Main Parts of Sanitary Butterfly Valves

If you have worked for a long time in the pharmaceutical and beverage industry, you know how important the butterfly valve is. But do you really know how they work? Better yet, do you know the main parts that make a butterfly valve?

Butterfly valves are used to control the flow of fluids. The structure and mechanism of a butterfly faucet are both similar to those of a ball valve. This means a spherical disc with a hole and a rod that passes through the disc so that when the faucet is open, the fluid supposed to flow through it will flow transparently. When the faucet is closed, the flow will obviously be blocked. There are four main parts that allow the sanitary butterfly valves to work: the body, the seat, the handle and the operator. Most high-performance butterfly valves have bodies that can easily fit between two pipes. This allows the valves to increase productivity. Keep in mind that not all valves are the same. Some are designed for drinks while others are designed for pharmaceutical drugs.

The technology behind sanitary butterfly valves has grown steadily over time. This explains why valves are used in many industries today. The regular butterfly, for example, comes from the group or rather family of quarter-turn faucets in a wide range of sizes for different uses and handling different degrees of temperature and pressure. The larger the size of a butterfly valve, the more pressure it can withstand. Each part of a butterfly valve contributes in one way or another to its usefulness and functionality. The pieces depend on each other. In other words, the valve may not work at all if a part is damaged or develops a glitch. The two most important parts are:

• Disc – The valve incorporates the use of a large rotating disc as it is a control device. It serves as the main fluid passage that the faucet controls. A first use of the disc was mainly to control the flow of water in the plumbing systems. This is logical because the valve is designed to be used to isolate and regulate the jet of water and other fluids. Keep in mind that the faucet can also be used to control the entry and exit of air in car carburetors.

• Seat – The seat uses the inference adjustment between the edge of the disc and the seat to ensure that the valve stops. The seat can be stuck to the body or can be stuck. The seat materials can be made of polymers or metal. The metal is mainly used when the valve has to withstand extreme temperatures.

Adamant Valves design and manufacture a wide range of stainless steel sanitary valves and fittings such as sanitary butterfly valves, sanitary ball valves, sanitary check valves, sanitary sight glasses, and sanitary unions, etc. They are widely used in the dairy, food, beverage, pharmaceutical, cosmetic, and other industrial markets.


Purpose of Tensile Testing and Its Use in the Plastic Industry

One of the most elementary tests that can be performed on a product is the tensile test to check the breaking resistance of a product. A test specimen is kept under tension to practice opposing forces acting upon opposite faces both located on the same axis that attempt to pull the specimen apart. These tests are simple to set and complete and reveal many characteristics of the products that are tested. These tests are measured to be fundamentally the reverse of a compression test.

Purpose of this test

Usually, this test is designed to run until the specimen breaks or fails under the specific load. The values that are calculated from this type of test can vary but are not limited to tensile strength, elongation, ultimate strength, modulus of electricity, yield strength, and strain hardening. The measurements taken during the test reveal the characteristics of a material while it is under a tensile load.

Tensile Testing for Plastics

Composites and Plastic are polymers with substances added to improve the performance or reduce costs. Plastic may be pressed or cast or extruded into sheet, film, or fibre reinforced plate, glass, tubes, fibre, bottles and boxes. Thermohardening or thermosetting plastics can be brittle or hard and temperature resistant. Thermosets include polyester resins, epoxy resins, polyurethane, phenolic resins, non-meltable, non-deformable and polyurethane. Polymers and plastics can be tested to measure product quality. The tests measure the weight required to split or break a plastic test material and sample elongation or stretch to that breaking load. The resulting data help to identify product quality and quality control checks for materials.

Plastic testing instruments, universal test machines provide a constant rate of extension because plastic tensile test behaviour is dependent on the speed of the test machine. The specimens loaded on the machines are set as per ASTM, DIN, ISO tensile test specimen dimensions. The Plastic tester machine should always rely on standard terms and conditions. As per ASTM D638, Plastic tensile test standards help to measure strain below 20 percent extension values. High strain can be measured by the machine, digital reader. Thin sheet sample testing is done as per the standard ASTM D882.

A high-quality testing machine is designed to measure the strength of a specific product, test method and product type. A good instrument can be the only solution required for your quality assurance and a worse choice can make you go in the loss too. So choose the instrument smartly.

Top 4 Ways of Forming Plastic and Their Advantages

Laser marking on steel is widely used on medical devices and different types of tools; click here to learn more.

Plastic manufacturing has emerged as one of the biggest industries today. From packaging material to heavy-duty industrial parts, uses of plastic are widespread. To a general onlooker, most kinds of plastic materials may look the same. Yet, their core material and Plastic Fabrication processes may vary greatly. Given below are some of the Plastic Manufacturing Processes and their advantages.

Injection Molding
Injection Molding is one of the most popular methods used by Plastic Manufacturers. The biggest edge of Plastic Molding is in its cost-effectiveness. Plastic Manufacturing Companies can produce goods at a large scale in the lowest costs. It also produces the least amount of waste and hence it is an ideal process for Plastic Manufacturing Companies. From small kitchen appliances to large bathroom fittings, this process is suitable for manufacturing all kinds of Plastic Profiles.

The process
The process is very simple. Resins are heated to their melting point. Then they are pushed into the mold. The molten plastic is pressed to take the form of the mold. It is an ideal process for manufacturing a large quantity of material at low cost. However, preparing the mold is very expensive. This process wouldn’t be feasible if the quantity of goods required is low.

Blow Molding
This is a highly adaptable process used in the Plastic Industry. It is commonly used for manufacturing bottles, containers and other kinds of hollow lengths. It is a fast and inexpensive process for making thin-walled hollow shapes. You can obtain complex shapes through this process.

The process
Air pressure is used in this process to expand the molten thermoplastic into the desired shape. It is a good process for obtaining seamless hollow shapes.

Custom Plastic Extrusion Molding
Custom Plastic Extrusion is an ideal method for getting Plastic Profiles with strict tolerance. You can work with a variety of materials and shapes in Custom Plastic Extrusion method. Accuracy and consistency are the biggest plus points of this method.

The process
The plastic resins are melted and passed through a die. You can get fixed plastic shapes with desired IDs and ODs. You will also have complete freedom to choose the shape and size of the material. The process uses dies and tools and hence it is very economical if the quantity of the order is high. Preparing the dies and tools is expensive and hence it may not remain a feasible option if the order size is small. Yet, if accuracy and consistency are your prime requirements then this process is for you.

Rotational Molding
The rotational molding method is also used for making hollow objects like blow molding. However, the raw material used in this process is different. It uses plastic powder instead of plastic resins. Nylon, ABS, polyethylene,and PVC are some of the common materials used in this process. This is an ideal process if you are trying to create large, hollow or concave shapes. It produces seamless and stress-free finished goods. The process uses simple and inexpensive tools,however, the tools need to be replaced frequently. The quality of finished goods obtained through this process is average and it is not an ideal process for precision forming.

The process
In this process, the plastic powder is placed in the mold and heated on a furnace. Once hot, the mold is continuously rotated to facilitate thorough coating of the mold’s inside. Once done the mold is removed and cooled in a controlled environment. Both heating and the cooling processes need to be monitored with great precision as quick temperature differences can lead to the formation of bubbles and warps.

Plastic Manufacturers use several other methods too like vacuum forming, compression molding, and thermoforming for making Plastic Profiles. The choice of process largely depends upon the kind of shape, consistency and order quantity required.

Important Information About Metal Finishing You Must Know

Though metals are hard to touch, they also have the tendency to decay. They also need protection to last longer and to meet the expectations of the users. It is because of that these materials are treated externally where they get an additional layer of another metal that protects it from all harms. Actually, the process works well for the iron or tin-based products that often get rusted and lose their natural integrity in some time. Actually, rusting is a natural phenomenon that weakens the material and makes it get weaker and weaker in some time. Usually, the process of applying that additional layer of metal on another is often termed as metal finishing.

The most important benefits of metal finishing are as follows:
1. Enhanced electrical conductivity
2. Superior strength
3. Vulcanization prospective
4. Bigger stain confrontation
5. Extra ornamental impact
6. Larger electrical resistance
7. Better chemical resistance

As far as methods of metal finishing are concerned, there are quite a few that are put in practice by the companies. Following are a few of them that are very much common in practice:

Plating- This is the most commonly-used process of metal finishing that adds an additional gleam to the material externally. Usually, layer of nickel or PTFE is added to the exteriors level of the material. In the opinion of the experts, Plating adds some benefits to the metals too. It makes them durable, corrosion resistant, and brings it an attractive look.

Brushing- This is yet another important process of metal finishing that does another big thing to the product. It removes the defects in the surface of the metal, in case it has any. Usually, this is very effective for iron as it has some rough surfaces on it due to some manufacturing causes or defects. Apart from adding a shine, it smooths the metal surface rather effectively indeed. The service providers use a brush to rub the external surface of the product to get rid of the sharp edges or other defects.

Buff Polishing- In the opinion of the experts, Buff Polishing is very much suitable for you in case you need a non-textured and smooth finish. The machine used for this process of metal finishing adds a glossy and shiny finish to the product. Undoubtedly, this process is the best for decorative finish. The technique of Buff Polishing is catching momentum these days.

Grinding- This special technique for metal finishing uses a high-power machine that works rather heavily to remove the sharp edges on the metal and makes it absolutely smooth. The machine makes use of varies physical properties that significantly include abrasion, solidity, and resistance. Without any doubt, the grinding is the most powerful method of metal finishing. It is very effective in smoothing different materials like gold, silver, copper, and platinum.

When it comes to making the product look good apart from making it durable and long-lasting, metal finishing becomes mandatory. You can always get in touch with the best metal finishing companies that have the latest infrastructure to take care of all the technicalities of this process.


Advantages of ASRS Integration in Your New Factory

Modern innovations and technologies have revolutionized the way a factory operates. Labor intensive manual processes have given way to automated ones with minimal or no human intervention. Computer controlled automation systems are part of each value addition area of the entire production chain, so are the various applications based software for managing them, resulting in higher production level at faster speeds with lower costs in a modern factory.

Warehouse or storage is one area of a factory where automation and technology have had relatively late and moderate entry. However, given the scope of applications and the projected value addition it can make in the entire production chain, there has been spurt in the use of automated systems and technologies.

Automated Storage and Retrieval System (ASRS) is one such essential part of a modern warehouse. Primarily, ASRS comprises of storage racks, storage and retrieval equipment and warehouse management system (WMS) that is a software application. Advancing from the conventional storage and retrieval equipment in a warehouse like AGVs, ASRS system is programmed to operate according to the load dimensions and speed of delivery for a particular load type. ASRS sends information related to the load movement to the Warehouse Management Systems which processes the data and guide automated warehouse control systems (WCS) that maneuver other warehouse equipment in tandem.

Conventional material handling systems involves manpower or small machinery to move and store the products in a warehouse using pallets which are stored using a single or double deep rack. This method is extremely tedious as it requires a large amount of data to be maintained manually about the location and the quantity of the products stored. A large investment in the resource is required to maintain the conventional material handling system; also it requires a large amount of time which leads to slow process chain in warehouse.

Advantages over conventional systems:

• Conventional forklifts and battery stackers offer increased resistance in capacity whereas ASRS offers the same working load at all the levels of storage system.

• ASRS systems are self maneuvered and hence requires no operator throughout the movement of equipment.

• Being the electrical equipment, no battery charging time or back-up batteries are required, hence ASRS offers uninterrupted availability.

• ASRS is capable of moving both standard and nonstandard loads in a uniformly-sized volume (container, pallet, etc.).

Factory owners are fast adopting ASRS for their warehouses. But, if you are setting up a new factory for your business, integrating ASRS in the warehouse can be actually a much beneficial and prudent decision, as you can reap benefits of cost effectiveness ease of integration better than retrofitting ASRS to an existing warehouse set up.

Benefits to the entire supply chain management in the new factory:

• ASRS requires small operating isle and are very dense system, minimizing floor space use and maximizing storage capacity and density.

• ASRS helps in cost reduction as it minimizes amount of unnecessary parts and products in an inventory

• ASRS reduces labor involvement in operations, thereby reducing the overall operational cost and increasing safety

• ASRS helps in modeling and managing the logical representation of the physical storage facilities

• It enables a seamless link to order processing and logistics management in order to pick, pack, and ship product in or out of the facility

• ASRS generates data about the movement of the loads (tracking where products are stocked, which suppliers they come from, and the length of time they are stored), to help companies in better inventory management.

• It enables the total production effectiveness in Raw Materials, Packaged Goods as well as Finished Products thus eliminating the chance of production failure.

Aircraft Hangar Doors Construction Manual

Hangar Doors Construction Guide

Before building a hangar door, first a pole evaluate the current state of airport or fleet, its operation and the feasibility of building a new hangar door. This includes the qualification of demand and requirements for aircraft hangars, assessment of the environment in which the project is carried out and assistance to key decision-makers & familiarize with the requirements of the FAA and the regulations governing the development of the airport and the construction of aircraft hangars.

Before going any further, identify the key persons who can help. These people could include:

  • airport managers
  • Representatives of the city
  • Airport engineers
  • airport consultants
  • the local organization of the EAA
  • other hangars owner

Research is the key

Start with an inspection of the waiting list of the aircraft hangar. If an airport does not have one, determine hangar space needed. Connect with those who show interest, learn about their commitment and plans for the future, and how much they are willing to spend. This is market research. Is customer interested in other places? Some people have their names on multiple waiting lists throughout the state. Does customer own a plane right now? decide this first to qualify these people, it must be verified.

Another way to gauge people’s interest in a hangar waiting list is to request a financial contribution for each listing.

The type of hangar depends on tenants and what is best in the airport. For example, interlocking T-sheds attract tenants because they offer the best weather protection for the least possible return. Coffered sheds generally attract owners with more money and bigger planes. These sheds are often more expensive to build, but they also generate significant revenue and should take much longer. Box sheds can also provide car washes, a conference room or a room for repairs and revisions of Hangar doors construction.

Planning is the key

Hangar doors construction Make sure to speak with local tenants, the airport manager, local EAA, etc.

Elements to consider

The search for the environment in which one wants to build is probably the most important element that can be overlooked. Airport supporters often believe that development will be easy and successful when the demand for space in aircraft hangars is high. Not always! Before looking for financing search for all the items at the airport. These elements include:

Support for airport owners: Whether it’s a private or public airport, help, and support needed to succeed. Key people to reach the airport manager, planning department, and city or county members. If an airport commission exists, please contact them!

Community Supporters: If the community does not support the project, it will be much more difficult. If the airport was good for the community in the past, feel comfortable with them. Do not accept it simply because ideas do not contain any complaints from the community & get support. Check with online forums, local newspapers and local residents to find out what people think about plans.

The Airport Master Plan: The airport should have a current FAA approved master plan, and show the airport’s ability to develop and plans for completion. It also shows an airport layout scheme. It is important that aircraft hangar project is highlighted in this management plan during the planning phase.

Zoning or land usage: The airport or city will have a plan from which to develop its own airport. Some areas will be available for aircraft hangars, others for commercial development, gas, combinations, etc. Some should be listed as permissions and should be free of any development or design. If there is not yet an area to develop a hangar, contact the airport manager. AOPA will also be a useful contact – Talk to Noise and Land Department.

Design Standards: Design standards do not apply to any airport. Some airports will have preferred architects and engineering offices for aircraft hangar projects. These companies will know the size, shape, design, door styles, etc. Get contact information from AeroDoors at a very early stage to make sure the right door choice is made. The airport manager may have a list of “favorite design agencies”.

Tenant Support: Although the waiting list in the hangar of the aircraft can wait to finish development, others may not show the same enthusiasm. For example, an existing hangar developer at the airport can see one as a threat. It is important that, determine the competition and ask for the opinion of others. first, a pole know what support is needed to overcome the competition.

Availability of funding: Existing airport revenues will be the main source of funding. Examples include state aviation, municipal bonds or private loans. Take a look at the FAA Airport Improvement Program.


Aluminium Foil and Resource Efficiency

From foil wrappers and household foil to semi-rigid foil containers, lids and laminated foil pouches, aluminium foil applications offer a versatile range of packaging solutions to meet today’s sustainability challenges. The physical properties of aluminium foil, such as the absolute barrier effect, lead to more protection and longer shelf-lives for the product contents, as well as better preservation of their nutritional and health benefits. The net result: less food waste and so greater resource efficiency. Also, less use of resources results in a reduction in the overall environmental impact and improved profitability.

In summary: More efficient packaging ultimately saves resources or, in other words, More is Less! The following lists some of the unique characteristics of aluminium foil and gives examples of how these properties provide resource- and energy-efficient solutions.

Barrier: Aluminium foil acts as an absolute barrier to light, gases and moisture providing almost perfect preservation of aroma, flavour and other product characteristics thus protecting product quality. It has a highly efficient barrier function to weight ratio, e.g., for 1 litre of milk packed in a beverage carton, only 1.5 grams of aluminium is sufficient to allow an ambient shelf-life of several months.

By enabling useful life of products for extended periods at room temperature, aluminium foil helps to reduce food waste and then to save the important resources used to produce the food. This also provides energy savings as products can be preserved without the need for refrigeration.

Product to pack ratio: In particular, due to the absolute barrier property even at very low gauges, aluminium foil allows for the development of packaging solutions that are both very efficient and very light. The product to pack ratio of flexible foil packaging is generally very high, potentially 5 to 10 times higher than for rigid packaging used for the same application.

High product to pack ratio means less packaging material is used to protect and deliver the same quantity of product. This also means less energy to transport the packaging whether empty or filled. And at the end of life there is significantly less packaging waste generated

Portion-ability: Foil’s excellent ability to be used alone or in combination with other materials (paper and/or plastic) provides flexibility to easily pack the product (food) into appropriate and convenient portions.

Providing food in appropriate quantities prevents both over-preparation and over-consumption which contribute to food wastage. Portioning also extends the shelf-life of the unprepared food by keeping it packaged and protected.

Material and space efficiency: Aluminium foil can efficiently be laminated with other materials to combine specific properties of several flexible packaging substrates in a complementary way for an improved overall performance and a very limited overall amount of material used. The reduced amount of material used in flexible foil packaging, plus the fact that it is delivered in the form of rolls, leads to more space efficiency during storage and transportation and enables further energy and cost savings.

Mechanical properties: Uniquely light yet strong, foil’s ‘deadfold’ characteristics allows it to wrap products tightly and without any glue or other sealing systems.

For household foil for example, the easy wrapping and reclose-ability helps to prevent food waste through appropriate protection of the goods at home or on-the-go and the possibility to efficiently preserve leftovers.

Thermal conductivity: Aluminium is an excellent conductor of heat and is able to withstand extreme temperatures. Alufoil is ideal for use in autoclaving, heat-sealing and other thermal processes (e.g. retort).

Excellent thermal conductivity minimizes the processing, sealing, chilling and re-heating times, thus saving energy and also ensuring a better protection of the organoleptic and nutritional quality of the food by flattening extreme temperature gradients within the product.

Electrical conductivity: Excellent electrical conductivity of aluminium foil enables high-
precision, contact-free sealing, thus widening the application range for efficient and fast filling technologies.The presence of aluminium foil in a packaging facilitates induction and ultrasonic sealing, saving materials and energy by minimizing the seal area and time.

Reflectivity: Aluminium foil reflects up to 98% of light and infrared heat. Good heat reflectivity saves energy during the cooling or heating of in pack prepared foods.

Multi-mode cooking: The unique combination of thermal, electrical heat transfer allows food to be cooked or re-heated by convection or microwave oven and/or in ‘bain marie’ systems. This flexibility in heating/cooking helps save time and energy during preparation.

Recyclability: Aluminium material is fully recyclable, endlessly, without any loss of quality. Increasing collection and recycling/recovery rates for aluminium foil and aluminium foil packaging means that an equivalent quantity of primary (i.e. virgin) aluminium will not be required by the industry. This represents a significant energy saving as processing recycled aluminium requires up to 95% less energy than the equivalent quantity of primary metal produced from bauxite.In Europe it is assumed that average recycling rate of all aluminium packaging is above 60%. The amount of aluminium packaging recycled greatly depends on the efficiency of the national packaging collection schemes in each European country. For aluminium foil trays and semi-rigid containers, the latest statistics show that the average recycling rate in Europe reaches about 55% thanks to continued work by the industry to promote the value of collection and recycling of aluminium foil packaging. For foil flexible packs, generally having a lower aluminium content since the packaging is often very thin and frequently laminated with plastics or paper, it is also possible to recover the aluminium from the scraps and reclaim it for closed-loop recycling, using specially developed technologies like pyrolysis. In the situations where aluminium foil packaging is not collected separately for recycling and enters an energy recovery process, a significant proportion of the aluminium in the packaging – even the thin gauge foil – can be collected from the bottom ashes for recycling. The part of aluminium which is oxidized during incineration is releasing energy which is recovered and converted to heat and electricity.

Resource Efficiency of aluminium foil packaging: For a given product there are often several effective packaging solutions able to perform the required functions. But some solutions are more resource efficient than others in that they use less resources.

Because of the combination of the unique above properties, aluminium foil packaging supports efficient use of resources and waste minimization throughout the lifecycle of the packed product. Not only does foil packaging help to save important food resources by offering optimised fit-for-purpose solutions with reduced risk of product waste, but it makes a very efficient use of packaging material over its entire life cycle.


Basic Components Of A Transformer

A transformer is a static device, which is responsible for the transmission of power in different voltage rating from one circuit to another through electromagnetic induction. It plays a major role in stepping-up or stepping down the voltage level. It is made of different components and having knowledge of each and every of its part, is compulsory to know the device better. Here are some of its basic components that you should know, so, let’s have a look at them.

  • Core: It acts as a major support of the transformer that provides a low reluctance path for the flow of magnetic flux. Its diameter totally depends on the voltage level, current and frequency as well, which is directly proportional to iron loss.
  • Winding: Another major component of a transformer is its winding made of copper. It gets classified into two different factors based on input as well as output supply, or voltage range. Most of the windings are made of copper because; it has high conductivity and ductility. This device basically has primary and secondary windings that make electricity transmission easier.
  • Insulating Materials: Basically, insulating paper and cardboard are two different insulating materials that are used for isolating primary and secondary windings with the main core. Apart from the above material, oil also falls into the same category that smoothens the working of the device and plays a vital role in improving its performance.
  • Tap Changer: It allows variable turn ratio and is mainly installed on high-voltage, low-current winding to minimize the current load during the working of the device. Its main function is to regulate the output voltage by adjusting a number of turns in one winding.
  • Cooling Tubes: As the name says, these tubes are ideal to lower down the heating level of the transformer oil. Their cooling is important to ensure the proper circulation and smooth operation of the device.
  • Explosion Vent: Explosion in the transformer is the major problems that occur due to the rise in the transformer oil temperature and to eject the boiling oil reaching the main point the use of explosion vent is compulsory in the device.

These are some of the common parts a transformer has; there are many others that you should know before investing in the same. In an order to invest in the ideal device, you first have to make a contact with the reliable company that meets your expectations and offer you the device without breaking your banks.


Understanding Oil Filtration And Contamination

A basic knowledge of oil filtration requirements, challenges, and solutions can make it easy to understand oil contamination and filtration. Oil filters are utilized in many types of hydraulic machinery to improve the quality of oil.

Oil filtration requirements

Filtration plays a key role in maintaining hydraulic equipment and fluids. The fluid contamination leads to corrosion, wear, unsatisfactory performance, and ultimately, the equipment failure. Most of the oil filters perform a simple function; trapping the particles in small holes and cleaning oil. The fluid passes through the filter while particles above a certain size are trapped. Engine oil filters have to deal with the following challenges:

  • To remove or mitigate contaminants that are detrimental to the engine
  • To have the ability to hold contaminants for the required service interval
  • To have the capacity to allow oil to flow through the filter and be cleaned

There are many types of oil filtration products that vary in terms of performance and efficiency. Some filters offer 50% efficiency which means they remove half of the contaminants in oil at a given particle size. We can test the efficiency of an oil filter through various techniques.

Cold flow is a common term experts use to describe a condition where oil experience restrictions while passing through the filter. It happens when oil becomes thick due to high soot and sludge levels. Cold flow also happens when filtration experts put filters on high efficiency. When the unfiltered oil is allowed to circulate in the engine, it stimulates corrosion process that affects engine life. Therefore, it is important to have the filters with the right balance of efficiency, cold flow ability, and capacity.

Capacity, efficiency, and cold flow ability are three critical requirements and mandatory to ensure extended engine life and performance. Real world testing is the only way to determine an optimal balance of these three requirements.

Contamination in lubrication systems

We must first understand the issues that arise due to oil contamination in an engine. We can classify contaminants in diesel engines lubrication systems as organic and inorganic. Organic contamination or sludge is formed due to by-products of combustion and comprises more than 70% of total contaminants in diesel engines. It limits the ability of a filter to trap harmful contaminants.

Inorganic contaminant also called dust is formed due to core sand, wear metal, gasket material, and dirt. A filter’s capacity to filter out dust does not reflect its performance. High-quality oil filtration systems play effective role in holding sludge along with the dust in the oil. Controlling these organic and inorganic contaminants can effectively reduce wear in the engine and improve equipment performance.


Types Of Bearings And Their Applications

So, how does the world work today? What makes it work the way it does? There are loads of things, such as airplanes, cell phones, electricity and so on and so forth. What you may not have noticed is the role of ball bearings that enable at least two of the most important functions. If they didn’t exist, we would not be able to use our cars. Similarly, engines wouldn’t work either. The role of these “balls” is to reduce the amount of friction in addition to keep the parts in place. Let’s read further about the types and uses of bearings.

Types of Bearings

You can find different types of bearings in the market. Let’s find out about those that play an important role in your routine life. They are most commonly used. That’s the reason you can buy them at any hardware store.

Radial: this is a simple type of bearings that can be found in most machines. They feature two metal circles. Between these metal circles, you can find small metal balls. If you want to see how they look like, you can open up an old drill or skateboard.

Pillow Block: This type of bearing is encased in a cabinet that can be connected to a surface that is parallel to the rotational axis.

Cam Follower: This is another common type of radial load bearing. It features a threaded rod. Typically, it is designed to ride on a cam follower in order to enable linear motion. However, their application is not restricted to cam follower only. They have many other interesting uses as well.

Ball Bushing: This type is used commonly in order to enable smooth movement of the heads of the CNC routers and 3D printers. Unlike the other types, this type of bearing is used in order to restrict radial movement. At the same time, it allows smooth linear movement.

Automotive Wheel: Generally, this type of bearing is used to overcome both the axial and radial load.

Thrust: As far as thrust bearings are concerned, they are used in automotives. This may have reminded you of bar tools and susans. Apart from this application, they are used for a number of other purposes as well, especially machines where smooth rotation is required, such as a camera.

Other Alternatives

You don’t need to opt for an alternative if your design works great with a simple bearing. However, you need to have a solid plan to make your system work. If you are in a rush, you can use some type of low friction stuff. For instance, you can make use of a Teflon washer as well. If possible, you may also want to give a go to the low-friction coatings.

If you are not on a tight budget, you may want to use bearings. As a matter of fact, it’s good to see your project working with ball bearings. As far as regular use is concerned, there is nothing better than bearings. So, keep using them for as long as you can
