Abstract

The disclosed clamping plate exhibits a particularly great spring action and it includes a clamping rim (10) and with spring tabs (20) which point radially inward and against which the cups of the self-aligning or cup-type bearing make contact. According to the invention the spring tabs (20) are particularly long and extend from the clamping rim (10). The tabs also bend inwardly over a bead (9) limiting the clamping rim (10). An especially inexpensive design from the aspect of production engineering and assembly is achieved in that the transition from the bead (9) to the plug-in hole (2) is rounded in the plug-in direction (6) of the clamping plate and the lower area of the bead (9) is designed as oil collecting groove.
