RCB-1T Wheel pump special bearing


1. PTFE/Pb Composition, 0.01-0.003mm, anti-abrasion material, which will form a lubricating film during operation.
2. Bronze powder layer, 0.2-0.35mm, which further strengthen the combination of the steel plate and PTFE layer and transfer the heat more quickly. 
3. Low carbon steel, bear high load transfer heat.
4. Copper/Tin plating layer, anti-corrosion.
