Patent ID: 8425121

Claim:
A ball rolling bearing comprising an outer ring and an inner ring between which the balls roll around an axis of rolling, spherical separators for the balls, and a raceway of revolution about the axis of rolling and along which the spherical separators roll, wherein the raceway is a channel section supported by an element secured in rotation with the inner ring and having a substantially semi-cyclic cross section of a diameter suited to that of the spherical separators so as to accommodate the separators resting in positions in which they are (i) retained laterally and free of contact with the outer ring (ii) at a radial offset angle smaller than or equal to 60°, the angle being measured in a radial plane between, on one hand, a straight segment connecting marks left on a same side of the axis of rolling by the respective centers of the balls and the separators in the radial plane and, on the other hand, the axis of rolling.
