  • Apparatus for fabricating a plain (sliding) bearing
    Patent number: 4658500
    Abstract: In a sliding bearing, a metallic layer is coated on a bearing base bush and is provided with grooved or helical or crossing indentations with intermediate elevations. Applied in a uniform manner onto the so-formed metallic layer is a sliding layer of softer material. Under pressure or application of shear forces, the material of the sliding layer provided above the elevations is forced through plastic shaping to flow into the indentations so as to provide a levelled and smooth sliding surface covering the metallic layer.
