Key Advantages

  • Metallurgical Performance: High-purity forged steel (GCr15/GCr15SiMn) resists heavy loads and continuous casting heat in rolling mill bearings.
  • Robust Sealing: Metal labyrinth seals block iron chips and cooling water ingress to protect internal roller raceways.
  • Fast Customization: Modular production delivers non-standard bearings up to φ5000mm in 15–20 days.

Custom Solutions & Applications

  • Cold & Hot Rolling Mills: Custom rolling mill bearings with ceramic coatings for extreme thermal and high-speed environments.
  • Legacy Retrofits: On-site 3D-scanned compatibility checks ensure seamless replacements for obsolete roller bearing units.
  • High-Speed Stands: Modified stamped steel or brass cages optimized for high-speed metallurgical bearing applications.

Quality Assurance & Support

Every bearing undergoes 12+ tests including ultrasonic flaw detection, 1,000-hour accelerated wear simulations, and pressure seal checks. We maintain 10,000+ units in global stock for 48-hour delivery, backed by IoT predictive maintenance.

FAQs

Q: Can your rolling mill bearings withstand 500°C in steel mills?
A: Yes! Our high-purity steel alloys and heat-resistant coatings ensure stable performance in high-temperature bearing environments.

Q: What's the lead time for a φ4000mm custom roller bearing?
A: Typically 18–22 days, including design validation, precision grinding, and final bearing inspections.

Q: Do you assist with legacy mill retrofits for rolling mill bearings?
A: Absolutely. We provide CAD modeling and on-site measurements for seamless bearing integration.
