Rolling Mill Bearing

High-Temperature & Heavy-Load Rolling Mill Bearings Built for Metallurgical Demands (Up to 300 Tons, 150°C)

30+ Years of Precision Engineering for Rolling Mills – Customizable, Durable, Fast-Delivery Solutions.

Built to Endure Extreme Conditions

Rolling Mill Bearings are the backbone of metallurgical equipment, designed to operate under relentless stress. At LUOYANG INNO BEARING CO., LTD, we engineer bearings that thrive in temperatures up to 500°C and handle loads exceeding 300 tons. With over three decades of expertise, our solutions are trusted by steel mills worldwide to minimize downtime and maximize productivity.

What Makes Our Rolling Mill Bearings Unique?

1. Engineered for Metallurgical Challenges

• Temperature Resistance: Operate reliably from -50°C to 150°C, even in continuous casting lines.

• Heavy-Load Capacity: Support up to 300+ tons with forged steel construction (GCr15/GCr15SiMn).

• Precision Performance: Achieve P5-level accuracy for cold rolling mills, reducing vibration by 40%.

2. Robust Design for Harsh Environments

• Sealed Against Contaminants: Metal labyrinth seals block iron chips and cooling water ingress.
• Impact-Resistant Structure: Four-row tapered rollers and integrally forged rings for 50,000+ service hours.

Available Sizes: Inner Diameter 100–1500mm | Outer Diameter 200–5000mm

Custom Solutions for Your Rolling Mill

1. Tailored to Your Specifications

We manufacture non-standard Rolling Mill Bearings up to φ5000mm, with:

• Custom coatings (e.g., ceramic layers for 150°C environments).

• Modified cage designs (stamped steel or brass) for high-speed applications.

• Legacy equipment retrofitting with 3D-scanned compatibility checks.

2. Faster Turnaround, Lower Costs

Our modular production cuts lead times by 30%. For example:

• φ3000mm bearings delivered in 15–20 days (vs. industry-standard 30+ days).

• 48-hour shipping for 1,000+ standard types from regional warehouses.

  

Quality Built into Every Bearing

12+ Rigorous Tests Ensure Reliability:

1. Flaw Detection: Ultrasonic testing for forging defects.

2. Lifespan Simulation: 1,000-hour accelerated wear testing.

3. Seal Integrity: Pressure tests against water/coolant ingress.

Result: 99.9% defect-free rate post-installation.

Global Support, Local Speed

• Regional Warehouses: Stocking 10,000+ units in Asia, Europe, and North America.
• 24/7 Technical Assistance: On-call engineers for installation guidance or emergency replacements.
• IoT Predictive Maintenance: Real-time vibration/temperature alerts via embedded sensors.
