AST11 Polytetrafluoroethylene (PTFE) Metric Series 1 Millimeter (mm) Nominal Strip Width (Ws) Strip Bronze Backed Plain Bushing

The AST40 Series Bushings are made of Steel bronze powder with PTFE/fiber, are dry bushings, and have the following layers:

1. PTFE polymer fibers mixture 0.01~0.03 mm are lead-free providing 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 0.20-0.35 mm, providing maximum thermal conductivity away from the bushing surface, also serves as a reservoir for the PTFE mixture.
3. Steel backing, provides high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating 0.002 mm, provides good corrosion resistance
