FAQs

Q: How do you customize bearings for φ5000mm furnaces?
A: Our engineers use 3D scanning to reverse-engineer legacy systems, then apply heat-resistant 42CrMo steel and P4-grade hardening for 150℃ stability.

Q: What testing ensures impact resistance?
A: Every port crane bearing undergoes 300-ton dynamic load simulations and 100,000-cycle fatigue tests.

Q: Can you deliver non-standard sizes in 15 days?
A: Yes! Modular production and pre-hardened materials let us ship φ3000mm+ bearings in 15-20 days.
