Abstract
The invention relates to a sliding bearing element (1) with a running layer (4) made from a first tin-based alloy and an additional layer (5) made from an additional tin-based alloy, said alloys containing at least one element from a group comprising Cu, Ni, Ag, Sb, As, Pb, Bi, Te, Tl and/or non-metal particles. The first tin-based alloy has a strength index FI of at least 5 and at most 25, and the additional tin-based alloy has a strength index FI of at least 0.3 and at most 3. The strength index of the running layer (4) is at least five times the strength index of the additional layer (5), and the strength index FI is defined by the equation, in which C represents at least one of the elements Cu, Ni, Ag; S represents Sb and/or non-metal particles; B represents at least one of the elements Pb, Bi, Te, Tl; and ω represents the total content of each of the tin-based alloy components assigned to the letters C, S, and B.
