GN 923.3 flat-faced solid disk handwheels are distinguished by their modern design and are suitable for applications where the handle should occasionally be withdrawn.
When the handle is pulled upward, it locks into a conical recess. The handle is now in its operating position. To fold it down, draw the handle back from the recess and lay it down into the neutral position inside the handwheel face. A compression spring holds the handle in both positions.
The removable plastic cover shrouds the assembly hardware such as screws and countersunk washers, as well as the shaft end.
Countersunk washers for handwheel retention, see GN 184.
Solid disk handwheel with or without revolving handle, see GN 923.
Retractable handle version with handle that swivels back automatically, see GN 923.7.
Two-spoked version, see GN 924.
Two-spoked versions with retractable handle, see GN 924.3 and GN 924.7.
Special inch and metric bores available upon request.
Other modifications such as keyways, set screw holes, etc. available upon request.
