The present invention relates to a multilayer radial bearing (1) having a front face (4) facing a supported element and a back face (6) opposite the front face, a support layer (2), a wear reduction layer arranged on the front face (4). (3) and a corrosion prevention layer (5) disposed on the back surface (6). The corrosion prevention layer (5) is composed of a copper-based alloy having copper mixed crystal grains, and here the corrosion prevention layer (5) The copper-based alloy may be a binary alloy having an alloy element from the group of aluminum, zinc, indium, silicon, germanium, antimony, or an alloy element from the group of aluminum, zinc, indium, silicon, germanium, tin, antimony, And / or its group and / or at least selected from the additional group consisting of nickel, cobalt, iron, manganese, bismuth, lead, silver, phosphorus and, if necessary, inevitable impurities derived from production A multi-layer radial bearing (1), formed by at least a ternary alloy comprising a further element, wherein the sum of these alloy elements is at least 1 wt% and at most 30 wt%. |
