Abstract

The rolling bearing (1) has an outer race (2) and an inner race (3). The outer race (2) is provided with a groove (4) near its end face to retain the rim (5) of the metal housing (6) of the seal (7). The rubber seal (7) is bonded to the housing (6) and has three flexible ribs (8)(9) and (10). The diameter of the inner race (3) is reduced at its end (14) so that a labyrinth is formed between it and the inward extension (13) of the housing (6). The sealing lips formed by the ribs (8)(9) and (10) retain the lubricant and the labyrinth excludes fibres, when the bearing is used in fibre winding machinery, which tend to wear away the sealing lips.
