Abstract

The bearing surfaces have a porous surface, later PTFE impregnated, applied by fusing metallic powders, layer by layer, onto the surface. The grain size of the powder layers diminishes with the distances from the bearing surface, giving good lubrication at the surface and good heat conduction behind. Alternatively the plate has trapezoidal grooves, with their long side lying on the sliding face. The grooves are fitted with PTFE which is applied over metallic powder fused to the base of the groove. Spiral type grooves are necessary to ensure even wear on the other bearing plate and there may be more than one groove.
