The PTFE coated surfaces of the coupling attachments GN 000.4 provide minimal friction between bearing surfaces even when lubrication is being neglected.
An oil hole is provided which in the completely assembled safety handwheel connects with the handwheel hub.
The coupling attachment is axially secured in the handwheel hub by a clamp nut.
