| SF-1 OILLESS BUSHING |
| Structure | |
| 1. PTFE/Pb mixture0.01~0.03mm, provides an excellent initial
transfer film, which effectivelycoats the mating surface of the
bearing assembly, forming an oxide type solidlubricant film. 2. Sintered bronze power 0.20-0.35mm, provides Max. thermalconductivity away from the bearing surface, also serves as a reservoir for thePTFE-lead mixture. 3. Low-carbon steel, gives exceptionally high loadcarrying capacity, excellent heat dissipation. 4. Copper/Tin plating0.002mm, provides good corrosion resistance. | |
