Abstract

A cast sliding surface bearing for guiding and supporting moving machine members consists of a light alloy matrix (4), which contains a cast-in shaped body (2), which constitutes portions of the sliding surface (6) and is made of a hard material and has open cavities, which contain infiltrated matrix material. In order to achieve improved tibological properties the open cavities of the shaped body are filled with matrix material, each of the hard portions of the shaped body which lie in the sliding surface has a size, measured in an axis, of .ltoreq.0.1 mm, and the distance between the hard portions of the shaped body, measured in an axis, is .ltoreq.2 mm.
