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
