Steel bronze powder with POM marginal bearings
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.
