Information
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 length of the handwheel hub l2 can be set by turning the clamp nut to the values given in the table.
