ABSTRACT:
A thrust bearing arrangement for a rotary shaft includes a main bearing mounted on the rotary shaft at a first axial location and an idler bearing mounted on the shaft at a second axial location spaced from the first axial location. Each of the main bearing and the idler bearing has an inner race in contact with the rotary shaft and a floating outer race. A thrust member is disposed between the outer races of the first and second bearings for transmitting axial thrust forces to a machine frame. A spring maintains a preload condition on the bearings.
