SHG series component type Harmonic Drive®, which are improved versions of the SHF series, are for high-torque operation.
Based on the development concepts of up grading the load capacity, strength reliability and extending the service life, SHG series component type Harmonic Drive® have been further improved in respect to the following performance capabilities as compared to SHF series products 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.,
SHG series unit type products are the same as SHF series products.
