Abstract
An assembly with a housing, a bearing, which is received in a bearing bore formed in the housing, and an annular compensation member. The housing and the compensation member are formed of materials having a larger coefficient of linear thermal expansion than a material from which the outer bearing race is formed. The compensation member is fixedly coupled to the housing and mounted about an outer bearing race of the bearing. The compensation member is configured to grow in a radial direction into contact with an inside circumferential surface of the outer bearing race when a temperature of the assembly increases from a first predetermined temperature to a second predetermined temperature.
