  SBP4 flanged washer, fibres and PTFE lined, STEEL backing 

Sintered PTFE/Fibre and Bronze on Steel Backing, surface with copper-plating or tin-plating
PTFE / Fibre + Bronze + Steel + Copper plating / tin-plating

Features
Suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics, the
transfer film reated 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.


Structures

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 thickness 0.002mm, provides good corrosion resistance.
