A composite multilayer material is described, which exhibits a relatively high specific load carrying capacity and relatively low wear. The composite multilayer material for plain bearings comprises a backing layer, a bearing metallayer ( ), a first intermediate layer ( ) of nickel, a second intermediate layer ( ) of tin and nickel together with an overlay ( ) consisting of copper and tin. The overlay ( ) comprises a tin matrix ( ), into which tin-copper particles ( ) are incorporated, which consist of 39 to 55 wt. % copper, the rest being tin. At high temperatures, as occur in the case of plain bearings used in internal combustion engines, the tin migrates into the second intermediate layer ( ) therebelow, resulting in concentration of the tin-copper particles ( ).

Composite multilayer material for plain bearings

A lead-free multilayer material for plain bearings and a process for the production of corresponding bearing shells for improved emergency running and mechanical load-carrying capacity characteristics. The multilayer bearing material comprises a lead-free copper alloy having a copper content ranging from 50 to 95 wt. %, and an overlay formed of a lead-free tin and copper having a tin content ranging from 70 to 97 wt. % and a copper content ranging from 3 to 20 wt. %.

Method of fabricating plain bearings

Sliding bearing element with lubricating oil pockets

A plain bearing shell (2a', 2b') exhibits a reduction in oil carbon formation on the plain bearing backing and an improvement in plain bearing interference fit during operation through a decrease in the relative movement between bearing backing and receiving bore. The ratio of the effective wall thickness W.sub.eff to the external bearing diameter D is defined by 0.012.ltoreq.W.sub.eff /D.ltoreq.0.02. The ratio of the installation free spread S to the external bearing diameter D is defined by: 0.025.ltoreq.S/D .ltoreq.0.05.
