    Abstract: Cylindrical rolling bodies, methods of producing the rolling bodies, and anti-friction bearings including the rolling bodies are disclosed. A method of producing the rolling bodies may include a) providing a spherical blank having a diameter (D) and a radius; and b) grinding the spherical blank into a cylindrical shape having a predefined diameter (d) and a length (L) that corresponds to the diameter (D) to form a cylindrical rolling body. After grinding, the cylindrical rolling body may have crowned end surfaces each having a radius corresponding to the radius of the spherical blank. Centerless cylindrical plunge grinding or centerless cylindrical throughfeed grinding may be used as the grinding method.
