Internal Freewheels FD are sprag freewheels without an inner ring. The customer s hardened and ground shaft is used as the inner track. The freewheels FD are used as:
The standard type and 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 be 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.

Two Internal Freewheels FD 40 CFR of standard type with bearing support as overrunning clutches in the drive of the transport rollers in a packaging distribution unit. In normal oper ation, the transport rollers are driven by means of the freewheels that are working in driving operation. At the withdrawal station, the arriving packages can easily slip off as the drive is overrun by the freewheel (freewheeling operation).
Internal freewheels FD in type standard 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.
The permissible operating temperature of thefreewheel is - 40°C to 80°C.
An oil lubrication of the specified quality must be provided.

for multiple-machine drives or to separate the iner-tia of masses of a driven machine from the driving machine after it has been switched off.
2. Indexing clutch
which turns a shaft step by step, thus achieving indexed material feed or a variable speed.
to prevent a machine shaft turning backwards. In this case the overrunning clutch acts as a brake
