FAQ

Q: Can you replace legacy bearings in older cranes?

A: Yes – share your existing bearing specs or let our engineers conduct on-site measurements.

Q: How do you ensure precision in large-diameter slewing rings?

A: We use CNC gear grinding and 100% post-production runout testing (≤0.05mm tolerance).

Q: What certifications do your bearings have?

A: ISO 9001, CE, and API 8C compliance. Region-specific certifications (e.g., GOST-R) available upon request.

Q: Do you support IoT integration for predictive maintenance?

A: Yes – we embed sensors to monitor wear, temperature, and lubrication levels in real time.
