Robotic Strain Wave Gearbox - GSL Series

GAM’s GSL Series Robotic Strain Wave Gearboxes provide zero-backlash and high torque in a small, lightweight gearbox for integration into machines and mechanisms.

Features

  • Drops in for popular competitor gearboxes
  • Strain wave (harmonic) gearing
  • Backlash ≤ 0.5 arcmin (≤ 30 arcsec)
  • High transmission accuracy
  • High reduction ratios in a single stage: 50:1 to 160:1
  • Simple design for integration into a mechanism or machine
  • High torque density with low inertia
  • Wide selection of models and configurations
