An improved bearing assembly supports a pair of parts for movement relative to each other. The bearing assembly includes a plurality of rotatable bearing elements such as rollers, which engage raceways on the parts. The bearing elements are disposed in openings formed in a longitudinally extending cage member which separates the bearing elements. The cage member is supported by wear pads which engage at least one of the raceways. The bearing elements roll along a central portion of the raceway. Wear pads support the cage member. To minimize scraping or marking of the portion of the raceway engaged by the bearing elements, the wear pads engage opposite sides of the raceway. The wear pads extend through openings formed in the cage and can be readily disconnected from the cage to facilitate replacement.
