| Message: | Composite bearing PTFE steel bush butterfly valve bushing1.PTFE/Polymer fibres mixture thickness 0.01~0.03mm. Lead-free bearing layer provides an excellent initial transfer film,Website:http://www.oilite-bearing.com, 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.Max. loadStatic250N/mm2 Max.
