Pom Composite bushing Characteristics 


Pom Composite lubricated bushing can be used for grease or oil lubrication applications, or in an oil-free environment

The standard parts contain grooves in the sliding layer of the contact parts, which can store grease or friction debris.


A smooth sliding layer can be designed and provided upon request

The composite bearing sleeve has the best performance under relatively high load and low speed, and the highest relative life

Composite bearings are used in environments of linear, oscillating and rotational motion

All kinds of bearing parts are available from stock

Assembly Shapes & Forms

Plain cylindrical bearings, thrust washers and sliding plates.POM STEEL BUSHINGS already prepared for assembly. The bushings are so designed that when press-fitting the bearing into the housing, the mating gap can be eliminated. However, the mating-point of the bearing should be positioned away from the load-zone.


Special Manufacturing Bushings:

Rod end bearings/spherical plain bearings/journal bearings On request, we can offer inch-sizes, standard size drawing,Lubrication Bearings, washers or sheets Strips.


Viiplus Pom Bushings

offers a broad range of sizes, forms and materials in monometallic and  bearings. Bimetal and metal bearings offer excellent corrosion resistance in industrial outdoor applications and in water, marine and offshore environments.


Metal-Polymer Plain Bearings Grease Lubricated

POM is a triple layer bearing consisting of copperplated steel frame, a middle layer of sintered bronze and a sliding surface of acetal plastic (POM).The sliding surface is provided with grease pockets which embeds the lubricant for gradual
release during operation. The slip layer also has a good ability to embed dirt and small particles that could damage the shaft. POM can withstand relatively high loads and is suitable for rotary and oscillating movements and structures with frequent starts and stops.

Note: note: VSB-20 series products can also choose different matrix materials according to different working conditions, such as: bronze substrate, stainless steel substrate, and "lead-free" formula products.Hxob-20y is an environmentally friendly lead-free product with the colors of orange, orange and blue.


VSB20 abroad (DX) boundary lubrication bearing with high quality low carbon steel or copper plate as substrate, the middle sintered porous spherical bronze powder, the friction surface rolling modified polyformaldehyde (POM and Pb), and through the high temperature solid combination as one of the three layers of plasticizing boundary lubrication bearing materials (also called prelubricated bearing material), the rolling and sliding bearing.

The material can provide better bearing capacity and wear resistance, friction surface with oil pits, in the presence of a small amount of lubrication medium, its performance is better than other sliding bearing materials.The product is suitable for working under normal temperature and medium (heavy) load, low speed occasions, to replace the traditional copper sleeve, which reduces the cost and extends the service life.Boundary lubricated bearings are divided into steel base and copper base.

Suitable for use in fatting or lubricating conditions, high bearing capacity, good wear resistance;


Suitable for rotating, reciprocating and swinging and other forms of movement and frequent starting, intermittent movement or heavy load and other occasions which are not easy to form oil film lubrication;


High load, low speed lubrication conditions with stable low friction coefficient and excellent wear resistance;


Friction surface layer can be secondary processing, bearing into the seat hole after processing, can further improve the accuracy of fit;


Long working time under boundary lubrication conditions, such as in the process of regular grease maintenance, can extend the service life;


Bearings for thin-wall structure, light weight, occupies a small volume, suitable for compact design;

Good dimensional stability, high mechanical strength;




1. POM thickness 0.30~0.50 mm. It provides high wearresistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.
