The invention relates to a multilayered bearing shell () comprising a back metal layer () as a carrier element for the layer structure and at least one further bearing layer joined to the back metal layer (), wherein the back metal layer () is made from a bronze. The back metal layer () contains in addition to copper, which forms the matrix of the bronze, tin in a proportion selected from a range with a lower limit of 1.25 wt. % and an upper limit of 12 wt. %, zinc in a proportion selected from a range with a lower limit of 0.25 wt. % and an upper limit of 6 wt. % and phosphorus in a proportion selected from a range with a lower limit of 0.01 wt. % and an upper limit of 0.5 wt. %.

Multilayered bearing shell

The invention relates to a method for the production of an anti-friction bearing element () comprising a carrier metal which forms a back bearing side and a bearing metal, wherein the carrier metal is made from a bronze-based alloy. The bearing metal is also made from a bronze-based alloy, wherein the hardness of said bronze-based alloy is reduced at least in some areas by heat treatment, so that in the radial direction of the anti-friction bearing a hardness gradient is formed with increasing hardness in the direction of the back side () of the anti-friction bearing element ().
