Application example
Internal Freewheel FNR 40 as an indexing freewheel for an incremental drive in the feed -
ing device of a wire processing machine. The indexing lever is driven by a crank operation.
The back and forth movement is transferred by the indexing freewheel in a gradual rotating
movement of the wire feeding device.
 
Mounting
The tolerance of the housing bore D must be ISO H7 or G7 and the tolerance of the shaft must
be ISO h6 or j6. The outer ring has to be completely enclosed in a stable housing to transmit the listed torques.
 
Lubrication
An oil lubrication of the specified quality must be provided.
