*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 following table. 

The allowable operating temperature of MJB is -20°C to 60℃.

※ The shaft's slip torque may be smaller than the coupling's rated torque depending on the shaft bore. MJB-BL MJB-GR MJB-RD MJB-WH MJB-EBL MJB-EGR MJB-ERD
