GN 923.7 Solid Disc Safety Handwheel, Aluminium, Retractable Handle
These solid disc handwheels, GN923.7, with retractable safety handle have a modern, attactive design.
These handwheels 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 must be pulled upward 90° against the torsion spring, to a stop and then pushed axially against the spring pressure into its hold position. By maintaining the forward thrust on the handle, the handwheel can easily be rotated. When the handle is released, the spring returns it back to the retracted position.
The removable plastic cover shrouds the fixing components such as screws, countersunk washers as well as the shaft end.
Aluminium die casting, hub machined, rim turned. Plastic coated, black, RAL2005, textured finish SW or silver, RAL9006, textured finish SR
Rim concentric and square to bore < 0,4
Retractable handle GN798.7. Plastic Technopolymer, black, matt. Retracting mechanism - Steel.
Countersunk washers for handwheel retention are to be ordered separately, see GN184
