Abstract
A race for a rolling-element bearing is characterized in that the race comprises at least one circumferentially-extending region 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.
