Composite Bearing INW-10 S SF-11S Stainless Steel Backing Bronze PTFE Metric Size
Composite Bearing INW-10 S SF-11S featuring stainless steel backing with bronze PTFE lining, designed for metric applications requiring superior performance in demanding environments.
Product Features
- Suitable for dry running applications with low coefficient of friction
- Reduced wear with excellent sliding characteristics
- Transfer film protects mating metal surfaces
- Ideal for both rotating and oscillating movements
- High chemical resistance and low water absorption
- Enhanced friction and wear resistance over standard CSB-50 range
- Widely used in chemical, food, pumping, valves, and ocean industries
Multi-Layer Structure
1. PTFE/Fibre Mixture (0.01-0.03mm)
Creates excellent initial transfer film that coats mating surfaces, forming an oxide-type solid lubricant film.
2. Sintered Bronze Powder (0.20-0.35mm)
Provides maximum thermal conductivity away from bearing surface and serves as reservoir for PTFE-Fibre mixture.
3. Stainless Steel Backing (SUS304, 314, 440)
Offers exceptional stability and heat dissipation in strong acid and alkali environments.
