Product Description
Internal Freewheels FEN
for press fit on the outer ring
with sprags
 
Features
Internal Freewheels FEN are sprag freewheels without bearing support. The outer ring is pressed into the customer housing. This makes compact, space-saving fitting solutions possible. The freewheels FEN are used as:
 Backstops
 Overrunning Clutches
 Indexing Freewheels
In addition to the standard type, it can be supplied for extended service life. Nominal torques up to 4 000 Nm. The torque is transmitted on the outer ring by press fit.
Bores up to 100 mm. Many standard bores are available.
 
Application example
Internal Freewheel FEN 82 SF as backstop fitted to the end of the intermediate shaft of a spur
gearbox in the drive of a bucket conveyor. In the case of a motor stop, the bucket conveyor must be held securely so that the conveyor goods do not pull backwards. The thin outer ring that is pressed into the housing enables a space-efficient fitting solution.

using other housing materials or smaller external diameters, we urge you to contact us regarding the transmissible torque. The tolerance of the housing bore D must be ISO P6 and the tolerance of the shaft must be ISO h6 or j6.
