＊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 MSF is -20℃ to 60℃. For more detailed information, please refer to Achieving Better Drive.
＊2： These are values with max. bore diameter.

Selection Based on Shaft Diameter and Rated Torque
The area bounded by the shaft diameter and rated torque indicates the selection size.
Selection Example
In case of selected parameters of shaft diameter of φ 8 and load torque of 1.4 N•m, the selection size is MSF-25.Ambient Temperature / Temperature Correction Factor
