摘要： Constant contact side bearings include a base presenting supports for cushions that are engaged by a top follower. In its pre-load position, rollers disposed on the top follower are urged into constant contact with a car body to control truck hunting. The cushions accommodate additional travel of the top follower to provide substantially higher load resistance for control of lateral car body roll resistance.
