Abstract: A method is offered for assembling an inner race for a roller bearing and an annular cage containing rolling elements, whereby the cage does not suffer permanent deformations, so that the inclination of the rolling elements is not impaired in any way and that the roller bearings ultimately produced by means of the units thus obtained have a much longer working life; which method is characterized by the fact that from the end of the inner flange of the inner race, material is removed in such manner that a revolving end plane is obtained of this flange which--with regard to the cardioid line of the race--is tapered from the inside toward the outside of the flange, following which the inner race and the cage containing the rolling elements are brought together in an axial direction, essentially concentrically and, through the exertion of force, are pressed together, whereby the rolling elements slide over the slanting end plane of the inner flange until they land in the track of the inner race.

Abstract: A method for assembly of an inner race for a roller bearing and an annular cage with rolling elements contained in openings in this cage, the inner race being placed essentially concentric with the cage with the rolling elements retained by the cage contained in a track fashioned in the outer circumferential surface of the race, the track being bordered on both sides by shoulders formed by opposing lateral surfaces of revolving flanges at, respectively, the inner and outer top surfaces of the inner race. The track is tapered from the outside toward the inside with regard to the cardioid line of the inner race and the rolling elements are formed of tapered cylinders. The cage and inner race are snapped together by pressing in the axial direction.
