Abstract

The arrangement according to the invention provides a sealing ring fastened to the end ring in a manner secure against removal by pulling or twisting. This sealing ring is provided with thickened extended arms and is fastened by snapping in the thickened arm sections behind an internal radial shoulder through openings in the flange of the end ring. The opening in the flange of the end ring may be economically manufactured, as by means of axial forms or cores, and without the need for additional radial cores, within the casting mold.
