Abstract:
The combination comprising:a bearing (1) having an inner ring and an outer ring housed in a belt pulley;a sealing disk (4) covering the bearing clamped between the head of a screw (3) and the inner ring of the bearing, means attaching said sealing disk directly to the inner ring axially and radially and projections (12,15) on the shaft of the screw underlying an edge of the disk (4) to secure the screw (3) to the disk (4) whereby the bearing (1), disk (4) and screw (3) form a unitary assembly for transport;the sealing disk (4) has a sleeve-like stamped section (6), which is pressed into the bore of the inner ring, and locking sections (13, 14), formed on the disk, which extend essentially in the radial direction, the edge areas of these locking sections cooperating with the radial projections (12) on the shaft (11) of the screw (3) to form a positive interlock, which prevents the screw (3) from falling out in the axial direction.
