Abstract:
A bearing liner allows a bearing to be mounted to a bearing housing even where the coefficients of thermal expansion of the bearing and the housing are different. The bearing liner includes a body portion and a mounting portion. The body portion has a cylindrical substrate that extends about a longitudinal axis of the bearing. The mounting portion includes mounting tabs that extend from the body portion of the liner. The mounting tabs allow the liner to be fixed to the housing and to the bearing. The mounting tabs are configured to flex relative to the body portion of the liner so as to allow for thermal expansion and contraction of the housing relative to the bearing while still securing the bearing to the housing.
