Before you specify this gearbox

Check efficiency, heat dissipation, duty and back-driving behavior for the particular model. Do not assume that every worm gearbox is self-locking.

  • Confirm continuous, peak and emergency-stop load limits separately.
  • Match the motor flange, shaft, mounting orientation and lubrication requirements.
  • Request the current drawing revision and selection calculation from the manufacturer.
