SBP4B flanged washer, fibres and PTFE lined, Bronze backing
Sintered PTFE and Polymer Fibres mixture and Bronze Powder on Bronze Backing
PTFE / Polymer Fibres + Bronze + Bronze Backing
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/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. Bronze backing, provides exceptional high load carrying capacity, excellent heat dissipation and very good
corrosion resistance.
