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 In the case of the standard type, every second sprag has been replaced by a cylindrical roller; this freewheel can accept radial forces.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.

. Application example
Internal Freewheel FDN 40 CFR in standard type with bearing support as an overrunning clutch on the shaft end of the main drive of a textile machine. The gear wheel is linked to an auxiliary drive. In normal operation (freewheeling oper ation) the inner ring overruns and the gear wheel with the pressed-in outer ring is at a standstill. During set-up, the machine is driven by the
slowly running auxiliary drive via the gear wheel and the freewheel that is working in driving
Internal freewheels FDN in standard type and type with P-grinding 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 torque is transmitted on the outer ring by
press fit. In order to transmit the torques specified in the table, the outer ring must be accommodated in a housing with an external diameter K. The housing is made of steel or grey
cast iron in minimum quality GG-20. When 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. The permissible operating temperature of the freewheel is - 40°C to 80°C.
An oil lubrication of the specified quality must be provided.
