TOP BEARING 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. TOB 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.
