Summary:The invention relates to a thrust washer (28) for an electric machine (10, 12) intended to be arranged on a shaft (16) between a bearing (18) and a rotor (14), preferably a rotating electrical contact element (24) impacted by brushes (38), and/or a disk pack (36) of the rotor (14). The thrust washer (28) is provided with an area for sealing having two end faces (32, 34). On each end face (32, 34), at least one radial abutment section (50, 52) for the bearing (18), or the rotor (14), is provided. The thrust washer (28) according to the invention is characterized in that it is made of at least one hard component (54) and one soft component (56), wherein the part of the radial abutment section (50, 52) abutting the rotor (14) and/or the bearing (18) is formed by the soft component (56).
