ABSTRACT:
A sliding element according to the invention comprises from approximately 30 to approximately 80% of fine and coarse graphite powders, from approximately 0.5 to 30% of lead-containing powder, and from 15 to 45% of an organic resin binder, all percentages being by weight based on the weight of the hot pressed body. Due to incorporation of both graphite carbon powder and lead-containing powder in to the organic resin binder, the conformability, wear resistance and low friction properties of the sliding element are superior to those obtained by a single addition of the graphite carbon or lead powder alone.
