A bearing (10) comprises an inner race (11), an outer race (12) and rolling members (13) interposed between the inner (11) and outer races (12) with a radial clearance c, greater or equal to zero, remaining. The bearing (10) also comprises a partial sealing member (15) attached to either the inner race (11) or the outer race (12) to one side of the rolling members (13) and which defines a substantially annular chamber between the partial sealing member (15) and the outer race (12) or the inner race (11) respectively. The substantially annular chamber has a length L and a width j and the width j is fractionally greater than the radial clearance c. The partial sealing member (15) may be formed integrally with either the inner race (11) or the outer race (12) or it may be formed separately and subsequently attached to either race as appropriate. The rolling members (13) may be in any appropriate form, for instance balls or rollers. <IMAGE> |
