Viiplus tri-layer maintanence-free bushing have a base of lower carbon steel, onto which a porous bronze layer is sintered. PTFE mixtures are impregnated into the intersice of this bronze layer after rolling process completed. VIIPLUS 10 SERIES has good physical & mechanical properties, also has certainly chemical properties. It is suitable for rotary, oscillating movement with performance of self-lub. Anti-wear, lower firction, lower noise.

Self lubricating plain bearings with PTFE sliding layer 


1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.

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 backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.

Screener Bucket Maintenance Free Bearings Excavator Loader Steel Bronze



steel-backed, sintered-bronze PTFE lined bearing.

used in dry, semi lubricated environment.

It has a wide applicable temperature range from -319 degrees F to 518 degrees F. The thin walls and

Light weight construction enable a compact design of the product.


It can substitute a conventional bearing where saving space is desired.

Steel Backed Bushing provides superior shock and impact load resistance. The Steel Backed PTFE Lined bushing maintains a low coefficient of

friction and is usable without lubrication at high load, low speed operations with excellent wear resistance.

Wrapped PTFE Lined (maintenance-free), self lubricated plain or flanged bearings, thrust washer and strip, Carbon steel shell with sintered bronze layer filled with PTFE



VSB-10 Self-Lubricating Multilayer Composite Bushing

· Bushing material suitable for lubricated applications
· self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Anti-friction bearing suitable for linear, oscillating and rotating movements
Material is designed to operate without supplemental lubrication and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very low absorption are a few of the features of this material. VSB-10 bushings will support rotary, linear and oscillating motion.
