*1: Correction of rated torque due to load fluctuation is not required. If ambient temperature exceeds 30°C, be sure to correct the rated torque with temperature correction factor shown in the following table.
The allowable operating temperature of XGS2 is -10℃ to 120℃.
※ The shaft's slip torque may be smaller than the coupling's rated torque depending on the shaft bore. XGT2XGL2

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 XGT2-CXGL2-CXGS2-C dimension tables. They are not guaranteed values.
Slip torque changes with usage conditions. Carry out tests under conditions similar to actual conditions in advance.
