PTFE Sleeve Split Bushings offer exceptional load-bearing capabilities, making them a highly effective solution for applications that require superior strength and durability. The use of PTFE (Polytetrafluoroethylene) material ensures smooth operation and low friction, while the split bush design allows for easy installation and removal. These bushings are able to withstand extreme loads and provide reliable performance even in harsh environments. Wh it's in industrial machinery, automotive components, or any other high-load application, PTFE Sleeve Split Bushings are a trusted choice for ensuring smooth and efficient operation.

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.
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.
