22324 Self-Aligning Roller Bearing JITO 120*260*86 - Chrome Steel GCr15 from China Suppliers and Factory for Heavy Loads

Structural Features of 22324 Bearings

Double-Row Roller Design: The 22324 bearings feature a robust double-row roller structure, consisting of drum-shaped rollers that provide exceptional capacity to handle significant radial loads as well as some axial loads. This innovative design allows the bearing to efficiently distribute the load, enhancing both load capacity and operational stability.

Self-Aligning Capability: The design includes a spherical outer ring raceway, enabling the inner ring and the rollers to tilt at specific angles. This self-aligning feature allows the bearing to adapt automatically to any misalignment between the shaft and bearing seat, as well as any bending or flexural deformation of the shaft, thus preventing potential overload scenarios.

Cage Composition: Typically, high-quality metal cages are employed, such as steel plate stamping cages or solid brass cages. These cages serve critical roles in maintaining roller separation, guiding roller movement, ensuring proper roller positioning within the raceway, and ultimately improving the overall accuracy and stability of the bearing.

As a leading manufacturer in China, our factory specializes in producing high-performance 22324 bearings, ensuring that our products meet the rigorous demands of various industries. We pride ourselves on being a trusted supplier, delivering quality bearings that enhance machinery durability and efficiency.

    Metallurgical Industry

    Widely used in rolling mills and conveyor rollers. Ensures stable, uninterrupted continuous operation under huge rolling forces and alternating loads.

    Industrial Fans & Blowers

    Compensates for shaft bending and angular misalignment in centrifugal fans and blowers, ensuring smooth and safe running performance.

    Papermaking Machinery

    Supports paper mill roller assemblies with high radial load capacity, accommodating micro-deformations during high-speed production.

    Installation and Maintenance

    1. Installation

    Ensure high matching accuracy of the bearing, shaft, and bearing housing. Use appropriate fitting tools to prevent surface damage. For 22324K tapered bore models, utilize adapter sleeves or withdrawal sleeves for precise mounting.

    2. Lubrication

    Select suitable grease or oil lubrication based on running speeds and working temperatures. Regularly inspect and replenish lubricants to minimize friction and extend overall bearing service life.

    3. Sealing

    Incorporate efficient sealing devices such as oil seals and gaskets to prevent dust, moisture, and harsh particulate contaminants from entering the raceways.

    Frequently Asked Questions (FAQ)

    What are the main technical characteristics of 22324 spherical roller bearings?

    The 22324 bearing features two rows of symmetrical barrel-shaped rollers, an inner diameter of 120 mm, outer diameter of 260 mm, and a width of 86 mm. It is engineered with high dynamic (1019 kN) and static (1120 kN) load ratings, offering excellent self-alignment under heavy radial and shock loads.

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

    The standard 22324 has a cylindrical bore for direct shaft mounting. The 22324K model has a tapered bore (1:12 taper ratio), allowing it to be securely mounted onto plain or stepped shafts using adapter sleeves (H2324) or withdrawal sleeves (AH2324), facilitating easier mounting and dismounting.

    What cage design options are available for the 22324 series (e.g., CA, CC, MB)?

    Different cage structures are supplied depending on working conditions: CA features a one-piece precision-machined brass cage with retaining flanges; CC utilizes two stamped window-type steel cages with a floating guide ring for lower friction; and MB features a solid two-piece machined brass cage guided on the inner ring, ideal for heavy-vibration applications.

    How do you choose between grease and oil lubrication for 22324 bearings?

    Grease lubrication is suitable for low-to-medium speed operations (reference speed ~2000 r/min) and simpler housing designs. Oil lubrication is recommended for higher operational speeds (up to 2600 r/min), higher ambient temperatures, or applications where efficient heat dissipation and particulate flushing are required.

    What internal clearance (C0, C3, C4) should be selected for heavy equipment?

    Standard C0 clearance is suitable for normal operating conditions with tight fitting tolerances. For high-temperature, heavy-load, or vibrating equipment (such as vibrating screens and crushers in mining), C3 or C4 clearance is recommended to prevent internal preloading caused by thermal expansion of the shaft and inner ring.

    Can JITO provide custom branding and OEM packaging for wholesale orders?

    Yes, JITO offers comprehensive OEM and ODM manufacturing services, including custom laser marking, client-specified packaging boxes, protective wraps, barcoding, and complete container shipping arrangements.
