ABSTRACT:
An adjustable roller bearing assembly adapted for use in a machine tool includes an elongated support bolt that rotatably supports a radially extending roller bearing, and a bushing adapted to be positioned within a bore of a support member and to which the bolt member can be threadably secured. The bushing includes an outer cylindrical portion adapted to be snugly received within a bore of a support member and a cylindrical through hole through which the bolt extends. The outer cylindrical surface of the bushing is eccentric with respect to a central longitudinal axis of the bushing so that the roller bearing and its associated support bolt can be radially adjusted relative to the support member by rotation of the bushing within the bore. The bushing is a one piece integrated sleeve, flange and threaded connector so that only the support bolt and bushing are needed to both clamp the bearing on the support and radially adjust the bearing position relative to the support.
