ABSTRACT:
A ball bearing includes an outer ring having a rotation axis and an inner ring, which rotates relative to the outer ring, and a plurality of bearing balls disposed between the outer ring and the inner ring. A plurality of rollers are peripherally disposed between the bearing balls and are radially disposed between the outer ring and the inner ring. First and second axially spaced tracks are disposed on opposite sides of the bearing balls for supporting the rollers. First and second plates, which support the first and second tracks, are connected to and supported by the inner ring. The bearing balls and roller portions have respective radial dimensions, and the outer ring and inner ring and roller tracks have respective radial dimensions. Such radial dimensions can be specified using given formulas, in order to provide substantially pure rolling friction, without any sliding friciton.
