Title: METAL/PLASTIC COMPOSITE SLIDING BEARING MATERIAL AND SLIDING BEARING ELEMENT PRODUCED THEREFROM
Abstract:
The invention relates to a metal/plastic composite sliding bearing material (2) for producing sliding bearing elements for lubricated applications, comprising a metal protective layer (4), in particular of steel, and a sliding layer (10), which is in sliding contact with a sliding partner and comprises a sliding layer material (8) on the basis of a fluorine-free thermoplastic, in particular PAEK or PEEK, and comprising fillers that improve the tribological properties; according to the invention, it is proposed that the sliding layer material comprises as fillers 1-40% by weight aluminium silicate in the form of substantially spherical particles and 5-40% by weight solid lubricant, in particular in the form of one or more of the following substances: zinc sulphide, tungsten disulphide, barium sulphate, kaolin, calcium fluoride, graphite, chalk or talc, and is formed free from fibrous additives and strength-increasing hard materials that have a Mohs hardness of greater than 5.
