China Suppliers Factory 22324 Self-Aligning Roller Bearing JITO 120*260*86 GCr15 for Heavy Load Applications

Structural Features of 22324 Bearings

Double-Row Roller Structure: The 22324 bearings feature a double-row design with drum-shaped rollers, making them capable of withstanding significant radial loads and some axial loads. This innovative structure allows for load distribution, enhancing the bearing's load capacity and stability, which is essential for high-performance applications. As a leading China supplier of quality bearings, our factory ensures these products meet rigorous standards.

Self-Aligning Function: With a spherical outer ring raceway, the 22324 bearings offer a unique self-aligning function. The inner ring and rollers can tilt at a specific angle, allowing automatic adjustment to misalignment between the shaft and bearing seat or any flexural deformation of the shaft. This feature is critical in preventing bearing overload, ensuring reliable operation in various settings, and establishing our reputation as a trusted supplier from China.

Cage Design: Our 22324 bearings utilize durable metal cages, including steel plate stamping or solid brass options. The cage serves to separate the rollers and guide their movement, ensuring they maintain the correct position within the raceway. This design significantly enhances the running accuracy and overall stability of the bearings, showcasing the exceptional quality from our factory.

    Application Areas

    Mining machinery: such as impact crushers, jaw crushers, vibrating screens, etc. These equipment will generate large impact loads and vibrations during operation. The high load capacity and self-aligning performance of 22324 spherical roller bearings can adapt well to these working conditions.

    Metallurgical industry: used in rolling mills, conveyor rollers and other equipment. When rolling steel, the rolling mill needs to withstand huge rolling forces and alternating loads. 22324 bearings can ensure the stable operation of the equipment.

    Fan field: When centrifugal fans and centrifugal blowers are running, the shaft may bend and misaligned to a certain extent. The self-aligning function of 22324 bearings can ensure the reliable operation of the fan.

    Papermaking machinery: For example, the roller support of the papermaking machine needs to withstand large radial loads and adapt to the slight deformation of the equipment during operation. 22324 bearings can meet these requirements.

    Installation and Maintenance

    Installation: During installation, the matching accuracy of the bearing, shaft and bearing seat should be ensured, and appropriate installation tools should be used to avoid damage to the bearing. For 22324K bearings with tapered holes, it is necessary to use a tightening sleeve or a withdrawal sleeve for installation to ensure the accuracy and reliability of the installation.

    Lubrication: Reasonably select the lubrication method and lubricant. Generally, grease lubrication or oil lubrication can be used. Regularly check and replenish lubricants to ensure good lubrication of the bearings and extend the service life of the bearings.

    Sealing: To prevent dust, moisture and other impurities from entering the bearings and affecting the performance and life of the bearings, appropriate sealing devices such as sealing rings and gaskets are required.

    Frequently Asked Questions

    What are the primary dimensions and specifications of the 22324 bearing?
    The 22324 spherical roller bearing features an inner diameter of 120 mm, an outer diameter of 260 mm, a width of 86 mm, and a weight of approximately 23.8 kg. It provides a dynamic load rating of 1019 kN and a static load rating of 1120 kN.
    What is the difference between a cylindrical bore and a tapered bore (K suffix)?
    Bearings with a cylindrical bore mount directly onto a straight shaft, whereas tapered bore bearings (designated with a 'K', e.g., 22324K) feature a 1:12 taper and are mounted using adapter sleeves or withdrawal sleeves for adjustable radial clearance.
    What operating conditions are self-aligning spherical roller bearings suitable for?
    They are specifically engineered for heavy radial and axial loads, severe impact vibrations, and applications prone to shaft deflection or mounting misalignment, such as crushers, rolling mills, vibratory screens, and industrial blowers.
    What clearance options are available for these bearings?
    Standard radial clearances include C0 (Normal), C2, C3, C4, and C5. The ideal clearance depends on working temperature differentials, press-fit tolerances, and operating speeds.
    Do you provide custom OEM services and packaging?
    Yes, comprehensive OEM services are available, including custom laser marking, tailored packaging options (individual boxes, pallets, or wooden cases), specific internal clearances, and precision tolerance grades (P0 to P4).
    What is the standard warranty coverage?
    Our bearings are covered by a 12-month warranty against defects in materials and manufacturing starting from the date of shipment, provided the bearings are installed and lubricated properly according to standard procedures.
