- Please modify rated/max. torque value with temperature correction factor when it’s higher than 30ºC.
- Max. torque/rated torque is the value regarding to a coupling’s self-durability and is not related to slip-torque between the coupling bore and the shaft.
- Please contact Sung-il Customer Service team for the special lengths (out of range).
