Composite bearings Design, Precision Bushings

Beautifully crafted leather products.

The performance of composite bearings, which also includes bushings, thrust washers, and strips, depends largely on the interaction of load, lubrication, surface roughness, sliding speed, and operating temperature in a specific application.

This makes it impossible to include all the information to cover every conceivable application. Therefore, we refer to the bushing application engineering service when needed.

Models and tables of dimensions For composite Bearing

Standard sliding materials with a high performance. They are designed for low-maintenance grease. This is the type of coating to be applied on this smooth ring. Self-lubricating PTFE (Polytetrafluoroethylene) coating that will require no maintenance. PTFE (Polytetrafluoroethylene) self-lubricating honeycomb coating with a grease hole that will allow maintenance and lubrication of the ring. The purpose of a bushing is similar to that of a bronze bearing, and the thickness is generally smaller than that of a bronze bushing. It will serve as a guide for the rotation of the shaft relative to a fixed reference, where minimum dimensions are necessary. The bushing wears slowly and takes up very little time. Some versions are maintenance free and can be run dry. We stock large size of bushings with same day dispatch and worldwide exporter.

The low friction bearing bushing

Self-lubricating bearings belong to sliding bearings, you can greatly reduce friction losses and surface wear, self-lubricating bearings can be designed to achieve smooth work, self-lubricating, reliable, oil-free bearings, no noise. Liquid lubrication conditions, isolated lubricant does not directly contact the sliding surface for impact absorption.

Self-lubricating bearing belongs to sliding bearing, you can greatly reduce friction loss and surface wear, self-lubricating bearing design can achieve smooth work, self-lubricating, reliable, oil-free bearing, no noise. Liquid lubrication conditions, isolated lubricant does not directly contact the sliding surface for impact absorption.

Self-lubricating bearings advantages and characteristics.

Self-lubricating bearings are also widely used, such as tobacco machinery, automobiles, printing presses, micro-motors, textile machines, motorcycles and agricultural and forestry machinery and so on. Self-lubricating bearings have their own advantages and characteristics.

1, there is a moderate amount of elasticity, can distribute the stress in a wider contact surface, to improve the bearing capacity.

2, self-lubricating bearings have good wear resistance, small coefficient of friction, long service life.

3、No oil lubrication or less oil lubrication, suitable for places where it is impossible to refuel or very difficult to refuel, can be used without maintenance or less maintenance.

4, static and dynamic friction coefficient is similar, can eliminate the crawling at low speed, so as to ensure the working accuracy of the machinery.

5, self-lubricating bearings for grinding shaft hardness requirements are low, without tempering treatment of the shaft can be used, thereby reducing the processing difficulties of the relevant parts.

Self-lubricating bearing

6、Self-lubricating bearings can form a transfer film during operation, which can protect the shaft of the grinding, no bite shaft phenomenon.

7、It can make the machinery reduce vibration, reduce noise, prevent pollution and improve labor conditions.

8、Thin-walled structure, light weight, can reduce the volume of machinery.

9、The back of the steel can be plated with a variety of metals, can be used in corrosive media; has been widely used in the sliding parts of various machinery, such as.

Printing machines, micro-motors, textile machines, tobacco machinery, automobiles, motorcycles and agricultural and forestry machinery, etc..

But the greater the starting friction. The shaft part of the bearing is called the shaft diameter part, called bush and shaft diameter together to go. In order to improve the casting of the inner surface layer of the friction material of the friction bearing surface properties called bearing lining.

Bearing and bearing lining materials are collectively referred to as bearing materials. Bearing applications are generally in low speed and heavy conditions under loading conditions, maintenance and lubrication or difficult operating areas.

POM type bearing bushing material

POM type material is filled with tetrafluoro-modified polyacetal plastic as the surface layer of the three-layer composite self-lubricating material, it is a benign boundary lubrication material, so it is especially suitable for high load and low speed under the rotary motion, swing motion and often under load opening and closing and not easy to form hydrodynamic lubrication of bearings, thrust washers, sliders, ball seats and other friction parts.

POM Bushes can make full use of trace amounts of grease and can be maintained for a long time without oiling under boundary lubrication lubrication conditions. Under completely oil-free lubrication conditions, POM Bushes have lower frictional performance and allowable PV values, so they are usually rolled out on the plastic surface with oil storage pits and coated with lithium-based lubricating grease or silicone grease during assembly.

POM composite bushing, Bronze sliding bearings, composite bushings and engineering plastics: POM bearings. With the exception of the sliding layer, composite bushings can be machined using conventional methods.

If the bushing is required to have a smaller width than the standard size, this can be easily achieved by turning. It is also possible to drill lubrication holes. However, any burrs, especially on the sliding surface, must be removed.

Strips can be bent, pressed, cut or drilled to suit individual applications. When cutting or drilling, we recommend doing so from the sliding surface side to avoid creating burrs on the sliding layer.

Any metal surfaces exposed as a result of machining should be protected to prevent corrosion.

Machining the bore of PTFE composite bushings

The PTFE composite bushing is ready for installation. Any adjustment to the bore (i.e., sliding surface) will reduce the life of the bushing and should only be done in special circumstances. If it is necessary to machine the bore, it should be resized and calibrated.

Machining the bore of POM composite bushings

Bushings made of POM composite are ready for installation. However, if necessary, the bore of the bushing can be machined to size while mounted in its housing.

Once we receive your request, we will contact you, and the qualified composite bushings will be recommended for your application.

POM Composite bushings surface polymer is resistant to chemical corrosion, so its corrosion resistance mainly depends on the steel back and the outer plating layer. The surface of the steel back is plated with copper or tin, which can effectively prevent atmospheric corrosion; if working in a corrosive medium, the steel back can be galvanized.

POM composite bushings are called pre-lubricated because their material is designed to operate with marginal lubrication. This type of bushing effectively fills the space between fully lubricated and dry sliding bushes. VIIPLUS offers a wide range of POM straight composite bushings

POM composite bushings Designs

POM composite sleeves are available as straight sleeves in metric and inch sizes. Pockets in the sliding surface make these sleeves suitable for applications requiring minimal maintenance in harsh operating conditions, for example in a polluted environment where grease cannot be supplied continuously or frequently.Therefore, the grease tanks must be filled before installation. Despite their compact design, POM composite bushings can withstand heavy radial loads and are less sensitive to misalignment. They are suitable for slow and linear rotation or swing movements.

POM composite bushings Advantages

  • Maintenance-free operation
  • Very good friction properties
  • High load capacity
  • High sliding speed

POM composite bushings Lubrication

POM composite bushing plain bearings are designed for extreme lubrication applications. The sliding surface of these POM composite plain bearings contains lubricant containers that must be filled before installation. It is not necessary to lubricate these POM composite bushing, but the presence of grease can significantly extend the life of the POM composite bushing. Grease can be applied regularly to protect the mating surface from corrosion.
