A sliding bearing element is characterized in that a bearing material that is bonded to the backing is disposed at least at the edges of the backing in form of wires in the circumferential direction and that a soft material is located at least in a space between said wires. At least one intermediate wire can be disposed between the two edge wires generally running in the circumferential direction. The method comprises the following processing steps: providing a strip of steel or any other material having the required degree of strength which forms the backing of the bearing to be produced, bonding at least one wire at each of the two edges of the backing strip, whereat disposing the wires in such a manner that said wires run in circumferential direction generally, and filling out the spaces between the wires with soft material.

Sliding bearing element and method of producing

A process for the production of sliding elements in which an overlay of lead-tin-copper is applied by electroplating to the prefabricated semi-finished product, and in which a ternary, fluoroborate-free electroplating bath is used without brighteners and with the addition of non-ionic wetting agents and free alkyl sulfonic acid. After the deposition of the galvanic overlay a heat treatment is carried out in the temperature range of 150&deg; C. to 200&deg; C. for between 1 and 100 hours. The multilayer material for sliding elements comprises at least a backing and an overlay of 12 to 16 wt. % tin and 7 to 11 wt. % copper, the rest being lead. The overlay comprises 15 to 25 wt. % particles of intermetallic compound Cu6Sn5.
