Abstract
In a sliding surface bearing for high loads, comprising a sliding layer (2), which has physically been applied in a vacuum directly to a bearing metal layer (1) and consists of a base material with finely divided inclusions (6), which are substantially insoluble in the base material at the operating temperature, substantial freedom from wear and a minimum tendency to mixing by rubbing are to be ensured in that all inclusions (6) have a lower hardness than the base material, which has been crystallized to form columns having a preferred orientation at right angles to the sliding surface (4).
