Abstract
Abstract A siding collar is provided for a fork-activated coupling clutch release bearing, including a collar body with a cast-in wear-resistant disc formed on a radial flange. A plurality of contact zones on one side of the disc contact the fork. On the bearing side of the disc the nonrotating bearing ring contacts the disc, the disc having a plurality of guide zones running essentially axially along the edge, with means for securing this bearing ring to the collar having guide zones for holding this bearing ring on the sliding collar against rotation on the sliding collar.
