Disk handwheels GN 321.7 with safety
retractable handle
GN598.7 are distinguished by modern design and are
suitable for applications where the handle must not
remain in the operating position.
In order to bring the handle into the operating position, it
has to be pulled out and up 90° to a stop against a tor-
sion spring, and then it is pushed against spring pressure
into its hold position. By maintaining the forward thrust on
the handle, the handwheel can easily be rotated. When
releasing the handle, the spring returns it back to the
retracted positionCountersunk washers for handwheel retention,
see GN 184.
Special larger than listed inch and metric bore sizes
available upon request.
Modifications such as keyways, set screw holes, cross
holes, etc. also available upon request.
