Abstract
A bearing system providing redundancy of bearing function. An inner race and an outer race are concentric and axially spaced apart from one another. A bearing set includes a pin of individually rotatable bearing wheels. The wheels are mounted by an intermediate retainer. A selector is provided to restrain either of the races from rotation relative to its respective wheel, thereby providing for selection of which race is to be active in providing relative rotation of the races.
