23124CA Spherical Roller Bearings High Load Double Row Spherical Bearing

23124CA Spherical Roller Bearing: 120mm Bore, 200mm OD, 62mm Width, High Load Capacity

The 23124CA spherical roller bearing is a double-row spherical roller bearing designed for heavy-duty applications. In the model designation, "231" represents the bearing series, "24" indicates a 120mm inner diameter (calculated as 24×5), and "CA" signifies the bearing features a brass solid cage with unique structural design and performance advantages.

• Self-aligning Design: The outer ring raceway is spherical with the bearing center as the center point, while the inner ring features two raceways inclined at a specific angle to the bearing axis, matched with two rows of barrel-shaped rollers. This structure provides excellent self-aligning capability, effectively compensating for shaft deflection during operation and installation misalignment. The typical allowable aligning angle is within 1°-2.5°, significantly reducing additional stress and wear caused by misalignment and ensuring stable bearing operation under complex working conditions.
• Cage Design: Features a brass solid cage (CA type) with high mechanical strength and excellent wear resistance. This design provides low-noise operation, creating a quieter environment for equipment operation, while effectively supporting rollers under conditions with multiple rolling elements and limited space. This ensures uniform distribution and smooth movement of rollers during operation, enhancing overall operational stability and reliability.
• Rolling Elements: Barrel-shaped rollers form linear contact with inner and outer ring raceways. This contact pattern significantly enhances the bearing's radial load capacity while also accommodating certain bidirectional axial loads, adapting to various complex stress conditions.

• High Load-bearing Capacity: Through scientific structural design and high-quality materials, the 23124CA spherical roller bearing can withstand substantial radial loads. When facing high-intensity pressure and impact forces in heavy-duty mechanical equipment, it demonstrates excellent stability and durability, meeting stringent high-load requirements in industries such as mining, metallurgy, and papermaking.
• Excellent Wear and Fatigue Resistance: Manufactured from premium bearing steel and subjected to rigorous heat treatment processes, the bearing surface achieves high hardness and good toughness. This enables stable long-term operation in harsh environments including high temperature, dusty conditions, and high humidity, effectively resisting wear and fatigue damage, significantly extending bearing service life, and reducing equipment maintenance costs.
• Stable Operation with Low Noise: The self-aligning function and well-designed cooperation between rollers and raceways effectively reduce vibration and noise generation during operation. This not only improves equipment operation stability and creates a more comfortable working environment but also enhances equipment operation accuracy, ensuring production process stability and product quality consistency.

• Mining Machinery: Widely used in equipment such as crushers, ball mills, and vibrating screens. The harsh mining environment subjects equipment to significant impact loads and vibrations. The 23124CA bearing's high load capacity and self-aligning function effectively ensure equipment stability, reduce failure frequency, and improve production efficiency.
• Metallurgical Equipment: Key components in rolling mill gearboxes and continuous casters frequently utilize this bearing type. Metallurgical production involves complex working conditions including high temperature, high load, and frequent start-stop cycles. The 23124CA spherical roller bearing provides reliable support for equipment operation, meeting the stringent requirements of the metallurgical industry for stability and reliability.
• Papermaking Machinery: Various transmission components in paper machines, including drying cylinders and press rolls, require substantial radial load capacity during operation. Due to equipment structural characteristics, shafts are prone to deflection and misalignment. The 23124CA bearing effectively adapts to these conditions, ensuring stable paper machine operation and maintaining paper production continuity and quality stability.
• Power Equipment: Rotating shafts in hydraulic generators, wind turbines, and large motors may experience deflection and vibration due to weight, electromagnetic forces, and other factors. The self-aligning function and high load capacity of the 23124CA spherical roller bearing effectively compensate for shaft deformation, ensuring stable motor operation and improving power generation efficiency and equipment reliability.
