* Correction of rated torque and max. torque due to load fluctuation is not required.However, if ambient temperature exceeds 30°C, be sure to correct the rated torque and max. torque with temperature correction factor shown in the table.MJC's allowable operating temperature is -20°C to 60°C.
** These are values with max. bore diameter.


Ambient Temperature / Temperature Correction Factor

-20℃ to 30℃ 1.00
30℃ to 40℃ 0.80
40℃ to 60℃ 0.70
