The PTFE coated surfaces of the GN 000.4 safety clutch assemblies provide minimal friction between bearing surfaces even when lubrication is being neglected.
An oil-hole is provided in the clutch mechanism to accept lubrication. In the completely assembled safety clutch handwheel, there is a lubrication fitting located in the hub of the handwheel to lubricate the safety clutch unit.
