Abstract
The clutch disc for a motor vehicle friction clutch comprises a hub on which a driving disc provided with friction linings is coaxially rotatably mounted through a torsional vibration damper. The torsional vibration damper has two mutually relatively rotatable damper parts which are rotationally elastically coupled with one another through springs. One of the damper parts is guided rotatably on the hub through at least one rolling bearing. The rolling bearing reduces especially the friction occuring in idling operation.
