Description:
DU bushing is a standard item of our company
DU bearing is also called PTFE bushing, SF-1 oilless bearing, PTFE lined bearing, plain dry bushes, DU bush.
Product Feature
Structure: Bronze Backing + Bronze Sinter + PTFE/PB
1. PTFE/PB mixture 0.01 - 0.03mm, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant 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. Bronze backing, gives exceptionally high load carrying capacity, excellent heat dissipation. Have very good corrosion resistance.
