* Correction of rated torque and max. torque due to load fluctuation is not required.However, if ambient temperature exceeds 30℃, be sure to correct the rated torque and max. torque with temperature correction factor shown in the table.MJT-C's allowable operating temperature is -20℃ to 60℃.
** These are values with max. bore diameter.
*** For transmission of backlash 0, please use a tight fit sleeve.

Change in static torsional stiffness due to temperature
This is a value under the condition where the static torsional stiffness at 20°C is 100%.The change of torsional stiffness within the range of allowable operating temperature is as shown in the graph.
Before using the unit, be aware of the deterioration of responsiveness.
