Product description


The cover cap protects the bearing from dust and dirt while covering fastening elements such as countersunk washers GN 184.

For fastening of the cover cap, the handwheel possesses a groove that is gripped by the elastic segments of the cap.

The cover cap is pressed on by hand and can be pried out with a screwdriver at the indented point.

The needle bearings are greased during assembly, providing ample permanent lubrication.

Application Guide

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 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, formlocking 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 handwheels are suitable for the intended purpose and use.

These handwheels are an advance development of the safety handwheels with Coupling Attachments 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 1. and/or 2. above also apply here. Owing to their type of construction, especially the cap, these handwheels are largely protected from dirt.
