ABSTRACT OF THE DISCLOSURE A drive having a plurality of thrust bearings includes a rotatable shaft located in a housing with a space therebetween and a plurality of spaced apart thrust bearings in said space. Two members axially movable with respect to one another are provided in the space between each pair of thrust bearings. A circumferential chamber is provided between the members with a resilient ring in the chamber. The volume of the ring is less than that of the chamber when little or no load is present. Under load the ring is deformed as the volume of the chamber is decreased due to axial movement of the members with respect to one another so that better distribution of the load between bearings occurs.
