Product Description

GN327 Disc Safety Handwheel, Aluminium, Fixed Bearing Flange

These safety handwheels feature the ultimate in health and safety at work standards because the handwheel, if disengaged, is mounted on a fixed component, the bearing flange. The wheel is fully disengaged from the rotating shaft.

The bearing flange can also accept the bearing of the shaft via the bearing bushing (mode 1). This bearing bushing is a dry bearing (DU bushing). Normally, the shaft has a separate bearing and the bearing bushing serves to center the bearing flange.

Centering can also be effected by a centering ring (mode 2) if the appropriate bore hole has been made at the machine side. In this case there is no need for the bearing bushes and no bearing friction (heating) will occur.


Handwheel body - Aluminium AL, Rim turned and polished.

Coupling attachments - Steel ST, nitrided. Bearing surface ground and/or PTFE coated.

Bearing flange - Blackened.

Revolving handles GN598 - Steel ST, plastic coated, black, matt
