The freewheel is built into the customer housing. This makes compact, space-saving
fitting solutions possible. The freewheels ZZ 2RS are used as:
 Backstops

Mounting
The torque is transmitted on the inner ring by keyway connection and 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 N6 and the tolerance of the shaft must be ISO k6. 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.
 
Lubrication
The freewheels are supplied grease-filled and with 2 RS seals.
