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 Company for evaluation.
