625 Stainless Steel Bearings Corrosion Resistant Self Lubricating Type High Hardness
1. Product Description
Valve Self Lube Bearings 625 Stainless Steel Bushings Corrosion Resistant are a triple layers composites one,the base material is excellent 625 stainless steel back and a film of heat resistant power filled PTFE being calendered onto the sintered spherical bronze interlayer. Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, forming a transfer film can protect the mating metal surface, suitable for rotary and oscillating movement. The stainless steel backing provides improved corrosio.
2. Specification
| Load capacity | Static load | 280N/mm2 | PVvalue limit | Oil lubrication | 70N/mm2.m/s |
| Dymamic load | 160N/mm2 | Dry friction | 3.6N/mm2.m/s | ||
| Oscillating | 80N/mm2 | Friction coef μ | 0.02~0.15 | ||
| Speed limit | Oil lubrication | 5m/s | Working temperature | -195℃~+450℃ | |
| Dry friction | 2.5m/s | Thermal conductivity | 58W/mk | ||
| Coefficient of linear expansion | 20x 10-6/k | ||||
3. Application
Valve Self Lube Bearings 625 Stainless Steel Bushings Corrosion Resistant are widely used in various valve,engineering machinery ,aerospace etc.
4. Advantages
The stainless steel back provides the bush with stronger mechanic strength and load capability. By combining the metals and the polymers together, the products are endowed with the lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the stainless steel back can be effectively preventing chemical erosion.It with super strength, extraordinary anti - fatigue characteristics, is widely used in aviation.
