739,838. Ball and roller bearings. DAIMLERBENZ AKT.-GES. March 4, 1954 [March 4, 1953], No. 6369/54. Class 12 (1). In a ball bearing comprising an inner race 2a on a sleeve 2, an outer race 7 and a row of balls 3, a lubricant block 6 is disposed substantially concentric with the bearing axis and is adapted to contact the row of balls 3. The ring 7 and block 6 are enclosed in a casing 8. In a modification, a frusto-conical end flange 8a of the casing causes the block 6 to maintain contact with the balls 3 on the upper side. Alternatively a conical surface 8b is provided on the casing as shown in Fig. 4. In another modification the block 6 is pressed axially into engagement with the balls 3 by a spring 9, Fig. 3. The balls 3 may be replaced by rollers. The invention is particularly applied to a clutch throw-out bearing.
