Hubs with eccentrical cam GN 919 are used for adjusting and clamping operations. As a rule these are fitted with a gear lever handle GN 310.
The cam offers the advantage that the clamping force remains constant in every position of its travel. In addition the cam is self locking.
Cylinder head shoulder bolts GN 732.1 can be used as bearing pins.
