Bearing surface ground and / or PTFE-coated
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 wheel hub.
