*1: 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.
*2: These are values with max. bore diameter.

●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 clamping + key 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.

These are test values based on the conditions of shaft dimensional allowance: h7, hardness: 34-40 HRC, and screw tightening torque of the values described in MJS-CS dimension tables. They are not guaranteed values.
Slip torque changes with usage conditions. Carry out tests under conditions similar to actual conditions in advance.
