Notes
Limits to confirm before you specify a planetary unit
Ambient outside -20°C to +40°C may require a custom discussion.
Hazardous areas requiring explosion protection need certified motors and system confirmation.
Standard supply includes unit, key, seals and plugs; flanges, torque arms and backstops are optional.
