Lateral thrust pads mounted to stop members projecting from bearing housings of a railway truck opposite respective pedestals of the truck frame under constant, compressive, slidable contact with such pedestals to absorb lateral thrust loads upon relative movement between the bearing housings and the truck frame. Because each thrust pad is in constant compressive contact with the opposite stop member, there is no unrestricted lateral movement with attendant increased potential for hunting. The thrust pad comprises an elastomer pad having a stiffness constant which varies in proportion to the amount the pad is compressed, thus providing for absorption of higher lateral thrust loads, while at the same time permitting nominal self-centering and curve negotiation lateral motions of the axle.
