Abstract
A slide bearing is described with a bearing metal layer on copper basis as applied to a carrier and a running layer made of an alloy of aluminum and tin which is applied physically onto the bearing metal layer in vacuum. In order to combine favorable resistance against wearing with a low inclination towards jamming with advantageous tribological properties it is proposed that the bearing metal layer consists of an alloy with 4 to 8% by weight of tin, 0.6 to 1% by weight of silver, 1 to 2% by weight of an iron phosphide and 0 to 0.15% by weight of carbon, preferably in the form of graphite, and the remainder of copper.
