Clutch release bearing device for motor vehicle, has ring unit forming sealing unit together with rotating ring and elastic unit, and truncated cone shaped section axially pre-stressed between retaining unit and radial section of idle ring

摘要

The device has a roll bearing with idle and rotating rings (1, 6), and a connecting unit (16) to connect an operating unit (15) with the bearing. The unit (16) has a retaining unit (19), and a ring unit has a truncated cone shaped section (18c) that is arranged in a radial direction between axial sections with small and large diameters, (18b, 18a) respectively. The ring unit forms a sealing unit together with the ring (6) and an elastic unit. The ring unit is centered on the idle ring, and section (18c) is axially pre-stressed between the unit (19) and a radial section (5) of the idle ring.
