Abstract
Into a raceway groove 3 formed between outer and inner races 1 and 2, there are incorporated a plurality of rolling elements 5, 5 of which outside diameters 5a 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 5 are arranged in such a manner that the mutually adjoining rolling elements 5, 5 cross each other alternately and also that the outside diameters 5a, 5a of the respective rolling elements 5, 5 are always contacted at two points with the raceway surfaces 1a, 1b of one race 1 and the raceway surfaces 2b, 2a of the other race 2.
