1. POM 0.30~0.50mm, has high wear resistance and low friction even only minute quantities of lubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the resin mixture.
3. Low-carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper plating 0.002mm, good corrosion resistance.

5. It is mainly used in the condition of strong acid and alkali, such as chemical industry, pumps,valves etc.
