Product Specification

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

I. Basic Information

The 23124CA spherical roller bearing belongs to the type of double-row spherical roller bearings. In the model, "231" represents a specific bearing series, "24" indicates that the inner diameter is 120mm (calculated by 24×5), and "CA" means that the bearing adopts a brass solid cage, with unique structural design and performance advantages.

III. Structural Features

1. Self-aligning Design: The outer ring raceway is spherical with the center of the bearing as the center, and the inner ring is equipped with two raceways inclined at a certain angle to the bearing axis, matched with two rows of barrel-shaped rollers. This structure endows the bearing with excellent self-aligning ability, which can effectively deal with the deflection deformation of the shaft during operation and the misalignment during installation. Generally, the allowable aligning angle is within 1° - 2.5°, which greatly reduces the additional stress and wear caused by misalignment and ensures the stable operation of the bearing under complex working conditions.

2. Cage: A brass solid cage (CA type) is adopted, which has high mechanical strength and good wear resistance. It not only has the characteristic of low noise, creating a relatively quiet environment for equipment operation, but also can stably and efficiently carry the rollers under the working conditions of multiple rolling elements and limited space, ensuring the uniform distribution and smooth movement of the rollers during operation, thereby improving the overall operational stability and reliability of the bearing.

3. Rolling Elements: The barrel-shaped rollers form linear contact with the inner and outer ring raceways. This contact mode greatly improves the bearing's capacity to bear radial loads. At the same time, the bearing can also bear a certain degree of bidirectional axial loads, adapting to various complex stress conditions.

IV. Performance Advantages

1. High Load-bearing Capacity: Relying on scientific and reasonable structural design and high-quality materials, the 23124CA spherical roller bearing can bear large radial loads. When facing high-intensity pressure and impact forces generated during the operation of heavy-duty mechanical equipment, it shows excellent stability and durability, and can meet the strict requirements for high-load bearing in industries such as mining, metallurgy and papermaking.

2. Good Wear Resistance and Fatigue Resistance: It is made of high-quality bearing steel and undergoes strict heat treatment processes, so that the bearing surface has high hardness and good toughness. This characteristic enables it to operate stably for a long time in harsh working environments such as high temperature, dusty and high humidity, effectively resisting wear and fatigue damage, significantly prolonging the service life of the bearing and reducing equipment maintenance costs.

3. Stable Operation with Low Noise: The self-aligning function and the well-designed cooperation between rollers and raceways enable the bearing to effectively reduce the generation of vibration and noise during operation. This not only improves the stability of equipment operation, creates a more comfortable working environment for operators, but also helps to improve the operation accuracy of the equipment, ensuring the stability of the production process and product quality.

V. Application Fields

1. Mining Machinery: It is widely used in equipment such as crushers, ball mills and vibrating screens. The mining operation environment is harsh, and the equipment bears huge impact loads and vibrations during operation. The high load-bearing capacity and self-aligning function of the 23124CA bearing can effectively ensure the stable operation of the equipment, reduce the frequency of failures and improve production efficiency.

2. Metallurgical Equipment: Key components such as gearboxes of rolling mills and continuous casters often adopt this type of bearing. During metallurgical production, equipment faces complex working conditions such as high temperature, high load and frequent start-stop. The 23124CA spherical roller bearing, with its excellent performance, can reliably support the operation of the equipment and meet the strict requirements of the metallurgical industry for equipment stability and reliability.

3. Papermaking Machinery: Various transmission components of paper machines, such as drying cylinders and press rolls, need to bear large radial loads during operation. Moreover, due to the structural characteristics of the equipment, the shaft is prone to deflection and misalignment. The 23124CA bearing can well adapt to these working conditions, ensure the stable operation of the paper machine, and guarantee the continuity and quality stability of paper production.

4. Power Equipment: The rotating shafts of power equipment such as hydraulic generators, wind turbines and large motors may produce deflection and vibration due to their own weight, electromagnetic force and other factors during operation. The self-aligning function and high load-bearing capacity of the 23124CA spherical roller bearing can effectively compensate for the deformation of the shaft, ensure the stable operation of the motor, and improve power generation efficiency and equipment reliability.
