FAQ – Professional Answers
- What makes IP67 better than IP54 for my factory?
- IP67 survives temporary immersion in water.
- IP54 only resists splashes and dust.
- Choose IP67 if you wash machines with hoses.
- Can I run this motor at 3000 RPM all day?
- No, 3000 RPM is the maximum speed.
- Continuous use above rated speed (2000 RPM) reduces torque.
- Check your duty cycle before ordering.
- Does the oil seal need replacement over time?
- Yes, oil seals wear after 2-3 years in oily environments.
- Inspect yearly for leaks around the shaft.
- Replacement is simple and low cost.
- Which Mitsubishi drive works best with HG-SR352J?
- Use MR-J4-350A or MR-J5-350A servo amplifier.
- Match drive power (3.5kW or higher).
- Older MR-J3 drives also work with adapter cables.
- What is the warranty and shipping policy?
- 12-month warranty covers manufacturing defects.
- We ship within 12-24 hours after order.
- Carriers: FedEx, UPS, DHL with tracking.
Buying Guide – Real Experience Tips
- Check your load type first.
- Medium inertia suits loads that change slowly.
- For fast start/stop, pick low inertia instead.
- Measure your shaft height carefully.
- This motor is heavier than 750W types.
- Reinforce your mounting plate if needed.
- Add a fan if running near 40°C all day.
- Motor stays cooler and lasts longer.
- Order cables at the same time.
- Use genuine Mitsubishi HG series cables.
- Third-party cables may fail IP67 seal.
- Keep spare oil seals in stock.
- Downtime is expensive.
- Seal part number is in the manual.
