POM Composite sliding washers are specially designed to operate with marginal
lubrication. The sliding surface has a highly effective grease retention system
with lubrication pockets, which serve as grease reservoirs. POM Composite consists of three bonded layers: a copper plated steel backing strip and a sintered porous tin bronze matrix covered with an acetal (polyoxymethylene, POM) resin.To protect the washer from corrosion the steel backing is tin plated. All POM Composite sliding bearings can be machined. However, any machining of the sliding surface should only be undertaken in exceptional cases.
