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.
