FAQ

Q: How do your bearings handle 150℃ environments?

A: Ceramic-coated cages and graphite lubrication prevent seizing and degradation.

Q: Can you make φ3000mm custom bearings?

A: Yes—our modular production delivers φ3000–5000mm bearings in 15 days.

Q: What certifications do you hold?

A: ISO 9001, CE, and ASTM A295 compliance with third-party fatigue testing.

Q: Do you support legacy machinery retrofits?

A: Yes! We redesign bearings to match original specs without altering housing.
