Product details


Composite bearing PTFE steel bush butterfly valve bushing





1.PTFE/Polymer fibres mixture thickness 0.01~0.03mm. Lead-free bearing layer provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.



2. Sintered bronze powder thickness 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 thickness 0.002mm, provides good corrosion resistance.
