Abstract
A linear bearing (20) with a height adjustment mechanism (58) including a stud (64) fixed to the bearing (20) and a tubular bushing (72) received over the stud (64) and mating with a threaded bore (86) in an end wall (88) of a mounting structure (12). A reaction nut (80) threaded to a protruding end of the stud (64) bears on a protruding end of the bushing (72), the other end bearing against the bearing (20) so that rotation of the bushing (72) in either direction causes a shift of the bearing (20) in either direction. A locking nut (92) threaded onto the bushing (72) is selectively advanced against end wall (88) to lock the bushing (72) in an adjusted position.
