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

Structural Features of 22324 Bearings

Double-Row Roller Structure: The 22324 bearings feature a robust double-row drum-shaped roller design that allows them to handle significant radial loads and some axial loads effectively. This innovative structure not only enhances load distribution but also boosts the bearing's overall capacity and stability, making it a reliable choice for various applications.

Self-Aligning Function: Designed with a spherical outer ring raceway, these bearings can adapt to angular misalignments between the shaft and bearing seat. This self-aligning capability ensures that the bearing can adjust automatically to any flexural deformation in the shaft, safeguarding against potential overloads and extending the lifespan of the bearing.

Cage Design: The 22324 bearings typically feature metal cages, such as steel plate stamping cages or solid brass cages. These cages serve a crucial role in separating and guiding the rollers, ensuring their proper positioning within the raceway. This design improves both the running accuracy and stability of the bearings, making them ideal for use in demanding environments.

As a leading supplier and factory in China, we are committed to providing high-quality 22324 bearings that meet international standards and customer requirements.

    Application Areas

    Mining Machinery

    Used in impact crushers, jaw crushers, vibrating screens, etc. These machines generate high impact loads and vibrations. The heavy-load rating and self-aligning features of 22324 spherical roller bearings ensure long-term stability.

    Metallurgical Industry

    Applied in rolling mills, conveyor rollers, and steel processing equipment. 22324 bearings withstand massive rolling forces and alternating heavy loads under harsh industrial conditions.

    Industrial Fans & Blowers

    Ideal for centrifugal fans and high-pressure blowers where shaft deflection or minor misalignment may occur during continuous high-speed operation.

    Papermaking Machinery

    Installed on papermaking roller supports to handle heavy radial loads while adapting to structural flexibility and slight thermal deformations.

    Installation and Maintenance

    1. Installation

    Ensure proper fit accuracy between the shaft, housing, and bearing. Use suitable mounting tools to prevent race damage. For 22324K tapered bore bearings, utilize adapter sleeves or withdrawal sleeves to ensure exact radial clearance.

    2. Lubrication

    Select proper grease or oil lubrication based on operating temperatures and speeds. Regularly inspect and replenish lubricants to maintain a reliable lubricating film and extend operational life.

    3. Sealing

    Equip effective sealing rings and gaskets to prevent dust, moisture, and abrasive debris from penetrating the bearing cavity, safeguarding bearing performance and longevity.

    Frequently Asked Questions (FAQ)

    What are the primary dimensions and specifications of the 22324 bearing?

    The 22324 spherical roller bearing features an inner diameter (bore) of 120 mm, an outer diameter of 260 mm, and a width of 86 mm. It weighs approximately 23.8 kg, with a dynamic load rating (Cr) of 1019 kN and a static load rating (Cor) of 1120 kN.

    What is the difference between cylindrical bore (22324) and tapered bore (22324K)?

    The standard 22324 bearing has a straight cylindrical bore for direct shaft mounting, while the 22324K bearing has a 1:12 tapered bore designed for mounting with adapter sleeves (such as H2324) or withdrawal sleeves (AH2324), allowing easier clearance adjustment on smooth shafts.

    What applications are best suited for 22324 spherical roller bearings?

    Due to their double-row self-aligning capability and high dynamic load capacity, 22324 bearings are widely used in heavy-duty machinery including mining crushers, vibrating screens, steel rolling mills, industrial fans, paper processing machines, and heavy gearboxes.

    What cage and clearance options are available for 22324 bearings?

    We offer multiple cage designs including CA (one-piece precision machined brass cage), CC (stamped steel cage), and MB (two-piece machined brass cage), with internal radial clearance classes ranging from C0 (normal) to C2, C3, C4, and C5 to match various speed and temperature requirements.

    Do you offer OEM and custom branding services?

    Yes, we provide full OEM and ODM services. Custom options include laser marking, customized brand packaging, specific clearance tolerances, specialty lubricants, and customized cage designs according to client technical drawings.

    What is the standard warranty period for your roller bearings?

    All bearings are backed by a 12-month quality guarantee from the date of shipment against manufacturing flaws and material defects under standard operating conditions and proper lubrication.
