Abstract
The invention relates to a bearing element (1) with a metallic support body (2), a bearing metal layer (3) arranged over the top and a polymer layer (4) arranged on the top of the latter, whereby the polymer layer (4) consists of a polyimide resin, molybdenum sulphide (MoS2) and graphite. The proportion of the polyimide resin in the polymer layer (4) is selected from a range with a lower limit of 60% and an upper limit of 80%, the proportion of MoS2 is selected from a range with a lower limit of 15% and an upper limit of 25% and the proportion of graphite is selected from a range with a lower limit of 5% and an upper limit of 15%.
