Product Description
Hydraulic Composite Bushings SF-1D Bronze PTFE Stainless Steel Material
High-performance composite bushings featuring bronze PTFE and stainless steel construction for demanding industrial applications.
Key Features
- Suitable for dry running with low coefficient of friction
- Excellent wear resistance and sliding characteristics
- Transfer film protects mating metal surfaces
- Ideal for 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 thickness): Provides excellent initial transfer film that coats mating surfaces, forming an oxide-type solid lubricant film.
2. Sintered Bronze Powder (0.20-0.35mm thickness): Offers maximum thermal conductivity away from bearing surface and serves as reservoir for PTFE-Fibre mixture.
3. Stainless Steel Backing (SUS304, 314, 440): Provides exceptional stability, load carrying capacity, heat dissipation, and resistance to strong acid and alkali environments.
