Before you specify this gearbox

Helical gearboxes are used in a broad range of industrial drives. Mounting position, service factor, thermal capacity and lubrication are part of selection, not just the nameplate power.

• 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.
