Advantage:
1 PTFE / Pb mixture 0.01-0.03mm, provides an excellent initial transfer film
2 sintered bronze powder 0.20-0.35mm, provides Max thermal conductivity away from the bearing
surface, also serves as a reservoir for the PTFE- lead mixture.
3 Low carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4 copper / Tin plating 0.002mm, provides good corrosion resistance.
