Mounting
Integrated Freewheels FON are without bearing support. Concentric alignment of inner and
outer ring must be provided by the customer. The permissible run out (T.I.R.) must be
observed. The Integrated Freewheel FON is centered via the outer track F on the customer attachment part and bolted to this. The tolerance of the pilot diameter of the attachment part must be ISO h6. The tolerance of the shaft must be ISO h6 or j6.
Lubrication
In the case of the type with sprag lift-off Z, at speeds in excess of the sprag lift-off speed, no
special lubrication is required; the freewheel functions maintenance-free. When operating
below the sprag lift-off speed, an oil lubrication of the specified oil quality must be provided.
