ABSTRACT:
The radial and bi-directional thrust bearing has a stationary, inner-annular race and a pair of rotatable outer races in tandem. The outer races each have a radially, inwardly-directed annular shoulder which is in contact with a radially, inwardly-directed annular shoulder of the other outer race. The inside diameters of the outer races are equal and larger than the outside diameter of a stationary, inner race, thus providing an annular space.
Two tandem sets of rollers are mounted in the annular space. A radially, outwardly-extending shoulder is provided on the inner race and extends partially across the annular space. A thrust ring is also mounted about the inner race. A sealing member extends across the annular space between the inner race shoulder and one outer race, and another sealing member extends across the space between the thrust ring and the other outer race. Thus, axial thrust loads in one direction are carried through the outer race shoulders, through one set of rollers, and through the inner race shoulder, and an axial thrust load in the other direction is carried through the outer race shoulders, through the other set of rollers, and through the thrust ring.
