ABSTRACT:
A bearing assembly supporting a shaft for rotation about its longitudinal axis comprising, a support, at least three outer races, a plurality of rolling elements, and at least three inner races. Each of the outer races comprises a circular inner surface of a respective ring member. The inner races comprise respective circular outer surfaces in the shaft which are concentric and disposed laterally of one another along the longitudinal axis. The ring members are disposed opposite to respective ones of the inner races to form laterally disposed annular spaces in which plural rolling elements are located. One ring member is arranged to be adjustably moved by a spring inward radially with respect to the axis from a first point on the circumference thereof to take up the clearances at that point. Another ring is arranged to be adjustably moved by a spring inward radially with respect to the axis from a second point on the circumference thereof located approximately 120 degrees from the first point to take up the clearances at that point. Once the two rings are moved to position they are locked in place with an adhesive.
