Abstract
Into a raceway groove formed between outer and inner races, there are incorporated a plurality of rolling elements of which outside diameters serving as the rolling contact surfaces thereof each has a curvature in the axial direction as well and also each of which has a radius smaller than the radius of the raceway surfaces of the outer and inner races. The rolling elements are arranged in such a manner that the mutually adjoining rolling elements cross each other alternately and also that the outside diameters of the respective rolling elements are always contacted at two points with the raceway surfaces of one race and the raceway surfaces of the other race.
