1. Steel bronze powder with PTFE/Pb dry bearings. The PTFE/Pb mixture (0.01~0.03mm) creates an excellent initial transfer film that effectively coats the mating surface of the bearing assembly, forming a solid lubricant film.
2. Sintered bronze powder (0.20-0.35mm) provides maximum thermal conductivity away from the bearing surface, acting as a reservoir for the PTFE-lead mixture.
3. Low-carbon steel offers high load-carrying capacity and excellent heat dissipation.
4. Copper/Tin plating (0.002mm) enhances corrosion resistance.
5. Suitable for dry running, low friction coefficient, reduced wear, good sliding characteristics, and forms a protective transfer film on the mating metal surface. Ideal for rotary and oscillating movements. High chemical resistance, low water absorption, and good performance with or without lubrication.
2. Typical Application:
Meets demanding criteria for long life and trouble-free performance, whether used with or without lubrication.
