RCB-1W Thrust Washers Trust Bearing Self lubricating Washers Sliding Washers

RCB-1W Self lubricating washer(DIN 1494 /ISO 3547)
MATERIAL STRUCTURE
		RCB-1W washer,is called dry washer 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.

	Long-time operation	1.8N/mm2.m/s	Coefficient of thermal expansion		11x11-6K
Operation Temp.		-195℃~＋280℃

APPLICATION CHARACTER

1. Working under oilless or minim oil state, maintenance free or just need a little maintenance.
2. Resist Abrasion, low coefficient of friction long operating life.
3. Operating in -195℃～+280℃
4. Good mending, low-noise, non-pollution
5. Thin wall, light, which can reduce the machine to small
6. Forming a transferred film during operation to protect shaft
7. Low demand to the shaft even no surface hardness treatment, which lower the cost of the mating components
8. No absorption to water/oil, small coefficient of Thermal emption, good thermal conductivity and size stability
9. The back of the steel strip can be plated with various metal, anti-corrosion
The products now are used in sliding components of different machines, such as auto machines, piston pump, gear pump, textile machine, auto-sides machine, Injection Machine, sports Machine office equipment etc.
