-
Peak torque is 133% of the maximum continuous torque. Coupling subjected to transient conditions should be evaluated using the Peak torque. Limit torque is 180% of the maximum continuous torque. Couplings subjected to a "one time" momentary load should be evaluated using the Limit torque.
-
Axial deflection is based on the maximum continuous torque listed. It is possible to trade off axial, torque and rated speed. Contact Goodrich Engineering for additional information.
-
Parallel offset equals the value shown multiplied by the distance between flexures.
-
The maximum bore capacity shown are for straight shaft ends. (Consult Goodrich for tapered shaft ends).
