Roughness Ra 0.8 zinc plating Sleeve Du Bushing with ISO9001/ TS16949 Approved

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

Specifications:

Description:

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

lubrication.

Structure

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.
