Boundary Lubrication Bearings refer to a type of bearings that operate in a lubrication regime where the lubricant film thickness is not sufficient to completely separate the moving surfaces, resulting in direct contact between the bearing surfaces and the lubricant film. This contact creates a boundary layer that partially supports the load, alongside the lubricating film.
Polytetrafluoroethylene () and Polyoxymethylene (POM) are commonly used materials for boundary lubrication bearings due to their unique properties. , known for its excellent chemical stability, low friction coefficient, and high temperature resistance, is often used as a bearing coating or lining material. POM, on the other hand, is a thermoplastic with good mechanical properties, wear resistance, and self-lubricating characteristics, making it suitable for low-friction applications.
When these materials are used in boundary lubrication bearings, they are often backed with bearing steel. Bearing steel is a high-carbon steel alloy that provides the necessary strength and rigidity to support the load while also resisting deformation and wear. The combination of or POM as the bearing surface material and bearing steel as the backing material results in a bearing that can effectively handle boundary lubrication conditions while minimizing wear and friction.

Shaft sleeve bushing
The VIIPLUS Metal-Polymer Bearings structure of this prelubricated Bule bushing consists of spherical powdered bronze sintered onto a steel backing and polyacetal resin bule impregnated into the surface.
VIIPLUS BLUE POM Coted bushing based sliding bearing also similar POM bushing, boundary lubrication bearing,SF-2 oilless bearing,dry bearing, POM lined plain dry bush. It has similar material structure with bushing. The difference is the layer with POM coated. We are leading exporter of POM Coated Bushing,sliding bearing,boundary lubrication bearing,Dry Bearing in china.
The self-lubricating bearings with the features of no oil or grease needed or only little oil or grease is needed during the operation and furthermore, so it has the advantages on the applicaitons to the machineries such as the Textile machines, Medicine machines, Food Machines, Beverage Bulking Machines with critical requirement on cleaning and environment conditions.
The structural characteristics
VIIPLUS metal composite boundary lubrication materials for high quality low carbon steel substrate, the sintering layer spherical porous copper powder, copper surface with modified polyformaldehyde (POM) or poly ( ketone) (PEEK) of wear-resistant lubricating materials as bearing layer, the rules of surface oil cavity not only can store fat, and can effectively buried outside the invasion of dust, improve the service life of bearing.This material has excellent mechanical bearing capacity. The intermediate copper powder layer can not only transfer the heat generated in the running process of the bearing in time, but also improve the bonding strength between the plastic layer and the substrate.The surface wear resistant material design based on POM or PEEK is suitable for grease lubrication. The bearing surface is regularly arranged with oil holes for storing grease to ensure the optimal distribution of lubricant on the whole bearing surface.
The product application
Products are widely used in
Automobile industry: pedal assembly, balance shaft sleeve, brake pliers, steering pin shaft sleeve and truck tail plate shaft sleeve;
Logistics machinery: truck, crane, truck crane, forest machinery, packaging machinery, etc.;And hydraulic motors, hydraulic cylinders, pneumatic components, agricultural machinery, etc.
In practical application, different filling materials can be added in the plastic surface layer POM/PEEK according to different operating conditions and environmental requirements

Metal-Polymer Bearings Bushings Boundary Lubricating Bearings food machinery SF-2L blue POM Bushes lead-free | VSB-20
Detailed information
Boundary lubrication lead-free bearing is improved on the basis of VSB-20. With low friction coefficient, good wear resistance and long service life, products can be used for higher environmental requirements such as food machinery because the product does not contain lead.
Steel + Bronze Powder + POM blue
Typical Applications
Generally for dry-running applications, shock absorbers, hydraulic applications, pneumatic cylinders, medical equipments, textile machines, agricultural applications , as well as in the office sector, etc.
Characteristics
VSB-20 Boundary lubrication bearing High Quality POM Bush China Manufacturer
· marginally lubricated bushings for grease or oil lubricated applications
· Standard parts contain grease indents in the sliding layer; plain sliding layer available by request
· Optimum performance under relatively high loads and low speeds
· Suitable for linear, oscillating and rotating movements
· Wide range of parts available from stock
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.
Strusture
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 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.
