*1: Values with no load fluctuation and rotation in a single direction. If there is large load fluctuation, or both normal and reverse rotation, select a size with some margin. 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 MOL is -20℃ to 80°C. For more detailed information, please refer to Selection Guidelines.
＊2： These are values with max. bore diameter.
