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.
