Frequently Asked Questions (FAQ)
- What is ultra-low inertia good for?
- It allows very fast acceleration and deceleration. Best for pick-and-place or scanning heads.
- Can I use this motor without a brake?
- No. The brake is built-in. You cannot remove it. For vertical loads, the brake helps hold position.
- Why no oil seal? What does that mean?
- No oil seal means oil mist can enter. Do not install in oily or wet areas. Keep it dry and clean.
- How to choose between HG-MR053B and HG-KR053BJ?
- HG-MR053B has ultra-low inertia – faster response. HG-KR053BJ has low inertia but IP65 rating. Pick MR for speed, pick KR for harsh environments.
- What about warranty and delivery?
- 12 months warranty. Ships in 12-24 hours via FedEx, UPS, or DHL. Tracking number provided.
Purchasing Guidance
- Check your drive: needs MR-JE-10A or MR-J4-10A.
- No oil seal – order only for clean, dry areas.
- Need faster response? Ultra-low inertia is your choice.
- For oily or dusty environments, choose HG-KR series (IP65).
- Buy cables and amplifier together for a complete system.
