FAQ

1. How do your bearings handle 500℃ in steel mills?

Our high-carbon chromium steel components undergo specialized heat treatment, maintaining structural integrity at extreme temperatures.

2. Can you make φ3200mm bearings for ship loaders?

Yes! Our modular production system delivers non-standard bearings up to φ5000mm in 15-20 days.

3. What ensures low noise in medical bearings?

Precision-ground rollers combined with brass cages reduce vibration, achieving <30dB in MRI systems.

4. How do you accelerate custom orders?

In-house R&D and 70% pre-fabricated components slash lead times to 70% of industry averages.
