MU Bushes
编号:
Steelbacking+ bronze powder with PTFE/Pb dry bearings
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. Low-carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating 0.002mm, provides good corrosion resistance.
5.Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, forming a transfer film can protect the mating metal surface, suitable for rotary and oscillating movement. High chemical resistance, low absorption of water and swelling. Also performs well with lubrication
