China 22320CCW33 Self-Aligning Roller Bearings Factory - Double Row, High Load Capacity, Low Friction, Durable Suppliers

Structure

Introducing our high-quality double-row spherical roller bearing, expertly engineered to support substantial radial loads and accommodate specific axial loads. This robust bearing design features two rows of rollers, where the outer ring is crafted with a common spherical raceway, while the inner ring presents two raceways that are inclined relative to the bearing axis. This innovative structure provides exceptional self-aligning capabilities, making it resistant to errors caused by shaft or bearing housing misalignment and bending.

In addition to effectively handling radial loads, our spherical roller bearings are capable of withstanding bi-directional axial loads, making them ideal for various industrial applications.

Main Applications: These bearings find extensive use in paper-making machinery, reducers, railway vehicle axles, rolling mill gearbox bearing seats, rolling mill rollers, crushers, vibrating screens, printing machinery, woodworking machinery, and a variety of industrial reducers. As a leading China supplier and factory of high-performance bearings, we ensure that our products meet the stringent demands of modern engineering.

    The 22320CCW33 is a double-row self-aligning spherical roller bearing. Its primary dimensions are an inner diameter (bore) of 100 mm, an outer diameter of 215 mm, a width of 73 mm, and a total weight of approximately 13.1 kg.
    2. What are the dynamic and static load ratings of the 22320CCW33 bearing?
    The basic rated dynamic load (Cr) of the 22320CCW33 is 860,000 N, and the basic rated static load (Cor) is 930,000 N, making it exceptionally suited for high radial and heavy two-way axial loads.
    3. What does the "CCW33" design feature represent?
    "CC" refers to a stamped steel cage and flangeless inner ring design optimized for higher load ratings and lower friction. "W33" indicates a lubrication groove and three lubrication holes located on the outer ring for efficient relubrication.
    4. What are the limiting operational speeds for grease and oil lubrication?
    For the 22320CCW33 bearing, the maximum recommended operating speed is 1400 r/min when using grease lubrication and 1800 r/min when using oil lubrication.
    5. In which industrial applications are these bearings most effective?
    These bearings excel in harsh, high-vibration, and high-load environments including metallurgical blast furnaces, steel rolling mills, mining equipment, industrial fans, gearboxes, vibrating screens, and heavy machine tools.
    6. What warranty and customization options are provided?
    We offer comprehensive OEM services (custom clearances from C0 to C5, precision grades P0 to P4, custom branding, and export packaging) backed by a 12-month standard warranty from the date of shipment.
