Frequently Asked Questions (FAQ)

• What is medium inertia good for?
  • It gives a balance between fast response and smooth running. Best for medium to heavy loads that need controlled moves.
• Can I run this motor without the brake?
  • No. Brake is built-in. You cannot remove it. For vertical or holding applications, the brake is essential.
• Why does this motor have an oil seal?
  • Oil seal blocks dust and oil mist. It protects bearings and encoder. Use in cleaner industrial areas.
• How to choose between HG-SR352BJ and HG-KR series?
  • HG-SR352BJ has medium inertia and high torque (16.7 Nm). HG-KR series has low inertia and lower torque. Pick SR for heavy loads, KR for light fast moves.
• What about warranty and delivery?
  • 12 months warranty. Ships in 12-24 hours via FedEx, UPS, or DHL. Tracking number sent by email.

Purchasing Guidance

• Check your drive: needs MR-J4-350A or similar (3.5kW class).
• Oil seal included – good for semi-dirty areas, not submersible.
• Need high torque? 50.1 Nm peak handles overloads.
• For lighter tasks, check HG-KR series (lower torque).
• Buy cables and amplifier together for full system.
• Confirm 200V AC power supply before ordering.
