* 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.

●All products are provided with hex socket head cap screw.
Recommended dimensional allowances of applicable shaft diameter are h6 and h7.
●A set of hubs with clamping type for one side and set screw type or other type for the other side is available upon request.
●In case of mounting on D-cut shaft, be careful about the position of the D-cut surface of the shaft.⇒Mounting and Maintenance

These are test values based on the condition of shaft's dimensional allowance: h7, hardness: from 34-40 HRC, and screw tightening torque of the values described in MJT-C dimensional table.
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.
