Abstract
A device for producing a curved lateral surface on a rolling element for a rolling bearing includes a grinding apparatus for grinding the curved lateral surface and a retaining apparatus having a control wheel with a convexly profiled peripheral feeding surface for retaining the rolling element during the grinding. The retaining apparatus may include a plurality of control wheels. The control wheel or the convexly profiled peripheral feeding surface may be formed from a ceramic, a resin-bonded synthetic, or a metallic material. The device may include a dressing apparatus for profiling the convexly profiled peripheral feeding surface of the control wheel.
