RCB-1T teflon bush du bushing excavator hydraulic cylinder bearing

RCB-1T Wheel pump special bearing
MATERIAL STRUCTURE
		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.
