Abstract

A sealed universal joint bearing includes a pot-shaped component having a disk-shaped base and a cylindrical wall projecting from a periphery of the base, and an inner surface of the base and an inner surface of the cylindrical wall define an interior of the pot-shaped body. At least one row of rolling elements are configured to roll along the inner surface of the cylindrical wall. A flange in the interior of the pot-shaped component has a flange surface against which end sides of the rolling elements are configured to slip during bearing operation, and the flange surface includes at least one formation configured to reduce a contact area between the flange surface and the end sides of the rolling elements.
