ABSTRACT:
Disclosed is a bearing assembly with thermal compensation. The bearing assembly includes a bearing mechanism defined by a pair of races and a plurality of bearing elements. The races are manufactured from a material having a coefficient of thermal expansion that is substantially different than the coefficient of thermal expansion of the material from which the bearing elements are manufactured. A thermal compensation mechanism of the bearing assembly is contiguous with the races. The thermal compensation mechanism permits movement of the races relative to the bearing elements in a direction parallel the rotational axis of the bearing mechanism as a result of the effect of temperature variations on the materials of the races and bearing elements.
