Abstract

In order to ensure full-surface thrust contact and coverage despite a low production and assembly outlay, even if the bearing is mounted slightly askew, a thrust and cover washer may be used which includes an inelastic first annular washer part axially thrusting and not contacting the rotor shaft, and an elastic second annular washer part positively joined thereto and resting sealingly on the rotor shaft. The first annular washer part may advantageously be made of plastic and the second annular washer part may advantageously be made of an elastomer.
