Product Description

High-Performance Large Cylindrical Roller Bearings for Extreme Industrial Demands

Engineered for metallurgy, port, and mining machinery

Large cylindrical roller bearings are the backbone of heavy-load machinery, designed to handle radial forces up to 300 tons while operating in extreme temperatures and abrasive environments. At LUOYANG INNO, we specialize in manufacturing bearings with inner diameters from 300mm to 2000mm, optimized for applications like rolling mills, mining crushers, and offshore wind turbines. Our modular design ensures these roller bearing units deliver 50,000+ hours of reliable performance.

Technical Specifications

Parameter Specification
Inner Diameter & Outer Diameter ID 300mm – 2000mm | OD 500mm – 3000mm
Width & Temperature Width 80mm – 500mm; -30℃ to +150℃ (higher custom options)

Key Advantages

  • Heavy-Load Capacity: Reinforced rollers and cages withstand dynamic loads up to 1,200 kN/mm².
  • High-Temperature Resistance: Materials retain hardness at 150℃+ in continuous bearing operations.
  • Rapid Customization: 15-20 day lead times for non-standard large cylindrical roller bearings (φ3000mm+).

Industry-Proven Applications

  • Metallurgy: Steel plant roll shafts using high-temperature cylindrical roller bearings reduce maintenance costs.
  • Port Machinery: Sealed bearing units provide extended service life in saltwater and marine environments.
  • Mining & Energy: Impact-resistant roller structures support vibrating screens and wind turbine yaw mechanisms.

Quality & Global Logistics

Every bearing undergoes 12-point quality testing including vibration analysis and load testing. We ship standard bearings within 48 hours and complete custom roller bearing designs in 15-20 days.

FAQs

Q: How do your large cylindrical roller bearings handle high-temperature environments?
A: We use heat-treated alloys and ceramic-coated rollers to maintain structural integrity in heavy bearing setups.

Q: Can I get a φ2500mm roller bearing in 18 days?
A: Yes! Our modular production system cuts lead times to 70% of industry averages for custom bearings.

Q: What certifications do you provide for these cylindrical roller bearing products?
A: All bearings include ISO 9001 and material test reports, with optional CE and ATEX compliance.
