BEARING UNIT, ESPECIALLY FOR MOUNTING A RUNNING WHEEL, A SPINDLE, OR ANOTHER MACHINE UNIT

摘要

A bearing unit (2) is provided for mounting a running wheel, a spindle, or another machine unit, for example. Said bearing unit (2) comprises a rolling bearing (4) with an inner bearing ring (8) that can be rotated about an axis of rotation (D), and an outer bearing ring (10). Multiple rolling elements (12) are arranged between the bearings rings. Pressure spring elements (16) are provided between a face (14) of one of the bearing rings (8, 10), in particular between the outer bearing ring (10) and an opposite spring accommodating ring (6). The bearing ring (8, 10) and the spring accommodating ring (6) can be axially moved relative to one another against the spring force of the pressure spring elements (16). In order to securely position the pressure spring elements (16), fastening elements (18) are provided which secure the spring accommodating ring (6) on the bearing ring (10) such that the pressure spring elements (16) are prevented from falling out.
