    • PROBLEM TO BE SOLVED: To provide an anti-friction coating which has a low lead content or has no lead at all.
      SOLUTION: The invention relates to an anti-friction coating for a multi-layered friction bearing made from a tin-based ally which, in addition to Zn, contains at least one element from the group comprising Sb and Cu as the main alloying element, optionally Pb and/or Bi, and unavoidable impurities originating from the elements during the manufacturing process, and the proportion of Sb is at most 20% by weight, the proportion of Cu is at most 10% by weight and the total proportion of Pb and Bi is at most 1.5% by weight and the total proportion of Cu and Sb is between 2% by weight and 22% by weight, and tin is present in the form of inter-metallic phases and as a tin phase with β-tin grains, and the β-tin grains in the tin-based alloy have at least one preferred orientation, and an orientation index M{hkl} based on the following formula of at least one set of network levels M{hkl} has or exceeds the value 3.0, and I{hkl} stands for the X-ray diffraction intensities for the {hkl} planes of the anti-friction coating and I
      O {hkl} stands for the X-ray diffraction intensities of the totally non-oriented tin powder sample.
