<p>A slide bearing particularly for use with internal combustion engines has a backing layer 11, an intermediate layer 12, provided with internal peripheral grooves located crosswise relative to the length of the bearing and longitudinally spaced from each other, and a slide layer 14 of a material which is softer than the material of the intermediate layer and fills the grooved portions. The grooves have a depth and longitudinal spacing with uniform or variable dimensions, at least one of the characteristics of depth (Fig 5) and spacing (Fig 4) being variable. This design allows a selective distribution of harder material and softer material on defined portions of the bearing as a function of specific operating requirements. Preferably, a diffusion or bonding layer 13 is provided in the grooved portions. <IMAGE></p> |
