AST Bearings

The AST11 Series Bushings

AST11 Bronze backed, Bronze with PTFE Series - Metric

The AST11 Series Bushings are made of bronze backed with bronze powder PTFE/Pb, are dry bushings, and have the following layers:

1. PTFE/Pb mixture 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surface of the bushing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity away from the bushing surface, also serves as a reservoir for the PTFE-lead mixture.
3. Bronze backing, gives exceptionally high load carrying capacity, excellent heat dissipation. Have very good corrosion resistance.

AST11 Series Features

Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, forming a transfer film can protect the mating metal surface, suitable for rotary and oscillating movement. The AST11 Series has a very high chemical resistance, low absorption of water and swelling. Also performs well with lubrication.
