Notes:
(1) For these specific models and ratios, the backstop
torque capacity is less than the gear drive maximum catalog rating for Class I
Service. Torque capacities shown are based upon 106 full load
cycles. If less than 106 full load cycles are required, the
backstop torque capacity can be increased. Consult the Dorris
Company for evaluation.
