“Self-lubricating Bearings for Textile Machinery”: VIIPLUS your partner of sliding bearings solutions for textile machinery . VIIPLUC from china have experience in the textile machinery spare bushing parts industry.
Spare Bushings parts of Spinning Textiles Mills Spinning Unit's Machinery self-lubricating bearings Spare Parts.
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. Self-lubricating Layer PTFE Mixture 0.01-0.03mm. After rolling process completed, PTFE mixtures are filled in intersice of bronze layer. Under normal
operation, Part of PTFE mixture on top layer will be removed and
transferred on the mating surface, forms a physically lubricating
film, which will reduced the firction coefficient and protect
the mating shaft.
2. Porous Bronze layer; The layer provides bonded strength of
Self-Lub. Layer.
3. Steel Backing The layer provides load & thermal conductivity
4. Copper / Tin layer
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.

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.
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.
