Features

CSG series component type Harmonic Drive®, an improved version of the CSF series, are for high torque operation.
Based on the development concepts of upgrading load capacity, strength reliability and extending service life, CSG series component type Harmonic Drive® have been further improved in respect to the following performance capabilities as compared to CSF series counterparts of the same size:

    • Rated torque improved 30%
    • Allowable Peak torque at start-up/stoppage improved 30%
    • Allowable maximum momentary torque improved 30%
    • Ratcheting torque improved 30%
    • Rated service life extended 42% (to 10,000 hours)
    • In respect to external dimensions, rigidity, angle transmission accuracy, input moment of inertia, etc.,
      CSG series component type Harmonic Drive® are the same as CSF series products.
