<p>The cluster (1) has a front sided thrust surface (8) for supporting a shaft (4) i.e. an armature shaft, of an electric motor, on a supporting surface (9). A grease pocket (10) is arranged adjacent to the thrust surface that is formed spherically. The grease pocket is formed as a circular groove, for accommodating grease. The grease pocket is limited radially outside by a peripheral bead (11), whose extension in axial direction is smaller than an extension of the thrust surface in axial direction.</p> |
