GN 321.6 Solid Disk Safety Clutch Handwheels Aluminum, with Needle Bearing

The relevant health and safety at work provisions state that handwheels must be attached to spindles such that they are not turned along together with the machine drive assembly. Safety clutch handwheels meet this requirement:

• If not in operation, the wheel is disengaged. Shifting it in axial direction (pushing or pulling) will intermesh two serrated bushings, engaging the wheel with the shaft.

• After releasing, the wheel will disengage again automatically.

A number of user notices for various design types are listed below. These notices are non-binding and given without liability. They do not constitute a warranty of proper function. The user must in any case determine whether the safety clutch handwheels are suitable for the intended purpose and use.

These safety clutch handwheels are an advance development of the Safety Clutch Assemblies GN 000.5 (with needle bearing).
The coupling elements have been specially developed for this type of handwheel and are therefore not intended for general use. Also, they are only intended for the “pulling” mode of engagement.

The user notices listed under the application notes of GN 000.4 and 000.5 also apply here. Owing to their type of construction, especially the cap, these handwheels are largely protected from dirt.
