[Note] 1) TR indicates rated torque and is used for life calculation. ...Km (material confficient) = 1.
2) TD indicates the judgment reference torque for the maximum torque (Normal), and TD torque/Maximum torque >1.5 is desirable.
3) TS indicates the judgment reference torque for the breaking torque (Highest), and TS torque/Breaking torque >1.5 is desirable.
