FAQ

1. Can your bearings handle OD >5000mm with P4 precision?

Yes! We've delivered φ5200mm non-standard bearings for hydropower turbines, maintaining P4 precision through proprietary grinding techniques.

2. How do you achieve <35dB noise levels?

Precision-ground rollers + brass cages minimize friction. Medical-grade bearings are further polished to Ra 0.05μm.

3. What’s your lead time for urgent orders?

Standard sizes ship in 48 hours. Expedited custom orders save 7 days via our modular assembly lines.

4. Do you support legacy machinery retrofits?

Our engineers provide free fitment analysis and CAD adaptations for outdated equipment.
