Torque ratings as listed are maximum steady torques per
application requirements. For general applications, dynamic
torques of ±35 percent of the coupling rate torques can be
applied to the listed torque ratings. Shock torques (e.g.,
start-up torque, etc.) of up to 200 percent rated torque are
generally acceptable.
Torque Requirements:
Torque (lb-in) = 63025 x hp
rpm
