    Rolling mill bearings are critical components in metal-forming machinery, designed to withstand extreme operational demands. Here's an in-depth overview based on the search results:

    1. Key Characteristics of Rolling Mill Bearings
    High Load Capacity: These bearings endure unit pressures of 2,000–4,800 MPa, 2–5 times higher than standard bearings, due to constrained roll neck dimensions and short roll lengths .

    Speed Variability: Operating speeds range from 0.2 m/s in low-speed mills to 100 m/s in high-speed wire rod mills, necessitating bearings tailored to specific speed requirements .

    Harsh Environments: Exposure to water, iron oxide debris (in hot rolling), and emulsions (in cold rolling) demands robust sealing systems to prevent contamination .

    2. Common Types of Rolling Mill Bearings
    Spherical Roller Bearings:

    Example: 24184CA/W33C3 (double-row, self-aligning) with a dynamic radial load capacity of 7,350 kN and static capacity of 12,600 kN. Designed for angular misalignment compensation, using GCr15 steel for rings and brass cages 2.

    Multi-Row Cylindrical Roller Bearings:

    Model 313839 features multiple rows for high radial load support, made from GCr15 or carburized chromium steel, with customizable clearance (C0–C4) .

    Tapered Roller Bearings:

    Double or four-row configurations (e.g., per JB/T 5389.2-2005 standards) are standardized for axial and radial load management in rolling mills .

    3. Operational Challenges
    Thermal Stress: Hot rolling involves water cooling, which can introduce contaminants, while cold rolling requires separation of lubricants from cooling emulsions .

    Maintenance Demands:

    Initial inspection after 1,000 hours of operation, followed by checks every 2,000+ hours.

    Regular cleaning and oil seal replacement to prevent failures .

    Material Requirements: High-grade steel (e.g., GCr15) and advanced heat treatments enhance durability under heavy loads .

    4. Industry Standards and Manufacturers
    Standards: China’s JB/T 5389.2-2005 specifies design and testing criteria for tapered roller bearings in rolling mills .

    Leading Manufacturers:

    Anshan Xinxing Rolling Mill Bearing Manufacturing Co., Ltd.: Specializes in large-scale bearings with ISO 9001 certification and patented designs 5.

    FV Bearing: Offers OEM services and collaborates with steel plants globally, emphasizing precision in production and testing .

    5. Maintenance and Longevity
    Inspection Intervals: Vary by load intensity:

    Every 3 months for heavy-load mills.

    6–12 months for moderate- or light-duty mills .

    Replacement Protocols: Defective seals must be replaced immediately to avoid contamination-induced wear .

    6. Emerging Trends
    Customization: Suppliers like FV Bearing provide tailored solutions, including optimized roller designs and material choices .

    Advanced Sealing: Innovations in sealing technology to handle mixed lubrication-cooling systems in cold rolling .
