Product Description

FDN Internal Sprag Freewheels Clutch Bearing One Way / Backstop Clutch

Features of FDN Backstop clutch
Internal Freewheels FDN are sprag freewheels with anti-friction bearing dimensions.
The freewheels FDN are used as:
 Backstops
 Overrunning Clutches
 Indexing Freewheels

The standard type and the type with P-grinding for increased service life and indexing accuracy do not have bearing support. In the case of the standard type, every second sprag has been replaced by a cylindrical roller; this freewheel can accept radial forces.
Nominal torques up to 2 400 Nm. The torque is transmitted on the outer ring by press fit.
Bores up to 80 mm. Many standard bores are Available.
