||GN 919 hubs with eccentric cam are
used for adjusting and clamping operations. Usually these are
used with a gear lever handle such as the GN 310 series type.
The cam offers the advantage that the clamping force remains
constant in every position of its movement. In addition, the
cam is self-locking.
