Steelbacking+ bronze powder with PTFE/fibre dry bearings
1.PTFE、 polymer fibres mixture 0.01~0.03mm,lead-free 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 mixture.
3.Steel backing, provides high load carrying capacity, excellent heat dissipation.
4.Copper/Tin plating 0.002mm, provides good corrosion resistance
5.Developed for high duty, oil lubricated, hydraulic applications...
Automotive suspension struts, shock absorbers guide bushing, hydraulic cylinders, gear pumps and motors and axial and radial piston pumps and motors. Mp4 Bushes is designed for use mainly under lubricated lubrications and shows excellent wear resistance, low static and dynamic friction coefficient.
