*Adjustment of rated and maximum torque specifications for load fluctuations is not required.
However, if operating temperature exceeds 30℃, please adjust rated torque and maximum torque as detailed in the table below.
The operational temperature range for XGT/XGS is -20℃~80℃. For more detailed information, please refer to NBK Coupling Selection Guidelines [PDF 171KB].
**Moment of inertia and mass figures based on maximum bore dimensions.
