Abstract
A self-lubricating wear part is formed of a polyacetal resin composition that includes (A) a polyacetal base resin, (B) an inorganic powder having an average particle diameter of 50 micometers or less, and a particle diameter distribution such that at least 95 percent of the particles have a diameter of 100 micrometers or less and (C) a fatty acid ester. The wear parts are particularly useful for slidable parts such as guide roller or guide pole.
