A race (13) for a rolling-element bearing (11) is characterised in that the race comprises at least one circumferentially- extending region (25,27) having a reduced stiffness compared with the remainder of the race . The or each circumferentially- extending region may be thinner than the remainder of the race, and may further comprise a hole or a slot. In a particular preferred embodiment there are two such circumferentially-extending regions, each extending around an arc of approximately 60 degrees in the circumferential direction. |
