Solid Disk Handwheels EN 524.3

Product description

Information

Solid disk handwheels EN 524.3 with locking retractable handle are designed for applications where it is necessary for the handle to return back to starting position after operation for safety reasons or lack of space.

These handwheels have the distinguishing features where the handle and the retracting mechanism are completely encased within the rim of the wheel.

In the operating position, the handle is secured by a taper detent. To fold it down, it is drawn out from the tapered recess. A compression spring secures the handle in either position.
Handwheel features rear finger grips.

Resistant to solvents, oils, grease and other chemical agents.

The connection between the operating element and the shaft is often made by a cross pin or a grub screw. As a result, the user is faced with relatively high assembly costs since cross holes on operating elements are usually not readily available. Components with cross holes according to GN 110 are not only manufactured and supplied at very competitive prices but there is also no need for time-consuming design drawings. However, the geometrical shape of some operating elements does not allow the use of this standard. The d₂ pin hole is intended for use with a spring pin.
