The torque is transmitted on the inner and 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 N6 and the tolerance of the shaft must be ISO n6. The permissible operating temperature of the
freewheel is +5°C to +60°C. Please contact us if the temperature is different to the given values.
The freewheels are supplied grease-filled and
with 2 RS seals.
