Radial rolling-contact bearing

摘要

A radial rolling-contact bearing with rolling elements (3) which roll between an inner race (1) and an outer race (2) has two radial seals (5), which are arranged in the region of the end faces of the outer race (2) and which close off the grease spaces (8) surrounding the rolling elements (3) from the outside. Each radial seal (5) is fixed to the outer race (2) and has a flexible sealing body (13) held by a metallic cap (11) and having a sealing lip (14) which rests in sliding fashion and under radial prestress against the inner race (1). Also provided are two centrifugal discs (6) which are fixed to the inner race (1), cover the radial seals (5) and form together with the radial seals (5) additional grease spaces, each of which is divided by an axial seal (15) into an inner grease space (17) and an outer grease space (18). According to the invention, each axial seal (15) is fixed to the metallic cap (11) and has a sealing lip (16) which rests in sliding contact with the centrifugal disc (6). By virtue of this arrangement, the position of the sealing lip (16) of the axial seal (15) remains unchanged when the inner race (1) rotates and centrifugal forces which would impair sealing are thus avoided. <IMAGE>
