Product Description

Roughness Ra0.8 zinc plating Sleeve Du Bushing with ISO9001/TS16949 Quality System




Accuracy Of Machining


Accuracy Of Grinding


Surface Roughness











Suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics.


Transfer film created will protect the mating metal surface. Suitable for rotary and oscillating movement,


high chemical resistance, lower absorption of water and reduced swelling. Also performs well with






1. PTFE / Fibre mixture thickness 0.01~0.03MM, 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 – fibre mixture.


3. Low-carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.


4. Copper/Tin plating thickness0.002mm, provides good corrosion resistance.
