FAQ

Are You Facing These Bearing Chock Challenges in Rolling Mill Operations?

Q1: Can bearing chock cracks cause an entire rolling line to shut down?

Integral Casting + Impact-Resistant Design
150-tonne-class integral casting eliminates weld stress concentration and improves impact resistance by 40%.

Q2: Does excessive bearing chamber wear lead to frequent replacement?

ZG35CrMo + Surface Hardening
Hardness reaches HB300–350, providing better wear resistance. Three rounds of spectral analysis are conducted: before furnace processing, after furnace processing and in the as-cast condition.

Q3: Chock can hidden defects lead to unexpected accidents?

Dual-Standard NDT + Full-Process Traceability
100% ultrasonic testing (UT) and magnetic particle testing (MT), with inspection videos and material composition reports provided.

Q4: Can delayed spare parts during peak seasons affect production?

Environmental Grade B Production Assurance
With a standard 16.36px delivery cycle and Environmental Grade B qualification, we ensure on-time order delivery and help prevent production interruptions.
