The theoretical nominal torque applies only for ideal concentricity between the inner and outer ring.

The maximum transmissible torque is 2 times the specified nominal torque. See page 14 for determination of selection torque.

Mounting

The lateral guidance of the Cage Freewheels can be effected either by a shoulder on the outer ring or by guard rings or guard discs which are fixed in the outer ring. Torque transmission capacity can be increased if several cages are arranged side by side. In this case please consult with RINGSPANN on transmissible torques. Please note the technical points on page 118regarding the sprag tracks.
