Product Description
GN327 Aluminium Disc Safety Handwheel with Fixed Bearing Flange
These GN 327 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). Usually, the shaft has a separate bearing and the bearing bushing centres the bearing flange.
Centering can also be affected by a centering ring (mode 2) if the appropriate borehole 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.
