Abstract
An antifriction bearing includes a plurality of rolling elements each having a lateral surface possessing a conical shape, with the rolling elements being positioned between a conical raceway and a cylindrical raceway to roll along the conical raceway and the cylindrical raceway. The lateral surface of each rolling element forms an angle with a center axis of the rolling element that is 3.degree. at maximum, and the lateral surface of each rolling element has a convex curvature that is superimposed on the conical shape. The bearing can also include a first bearing ring having a running surface constituting one of the conical and cylindrical raceways. An antifriction bearing arrangement incorporating such an antifriction bearing is also provided with a stop element having a stop face contacting the end face of each of the rolling elements.
