Double Row Self Aligning Spherical Roller Bearing 23022 High Load For Mining Machinery

As an important member of spherical roller bearings, the 23022 bearing plays a crucial role in mechanical transmission systems, widely serving multiple fields such as industry, agriculture, and energy, and helping various equipment operate efficiently and stably.

The 23022 bearing adopts a unique double - row spherical roller structure. The outer ring is equipped with a smooth common spherical raceway, and the inner ring is provided with two raceways that are inclined at a certain angle relative to the bearing axis. This exquisite design endows the bearing with excellent self - aligning ability. When facing the angular alignment error between the shaft and the bearing housing or the shaft bending, it can automatically adjust the contact position between the rollers and the raceways, ensuring uniform load - bearing of the rollers, reducing local stress concentration, and minimizing wear. Thus, it significantly prolongs the service life of the bearing and ensures the stable operation of the equipment. For example, in the shafting of large motors, due to thermal expansion and contraction during motor operation or slight deviations during installation, the shaft may bend to a certain extent. The self - aligning characteristic of the 23022 bearing can effectively compensate for these errors, allowing the motor to run smoothly and avoiding vibration and abnormal wear caused by shaft misalignment.

1. Dimension Specifications: The bearing has an inner diameter of 110mm, an outer diameter of 170mm, and a width of 45mm. Such standardized and moderate dimensions enable it to perfectly fit the shafting and installation space of many mechanical equipment. Whether it is compact small - sized equipment or large industrial equipment, it can be easily installed and used, with extremely strong versatility.
2. Load - bearing Capacity: It performs excellently in terms of load - bearing performance. The basic rated dynamic load can generally reach 293kN, and some high - quality models can even reach 326kN, with a basic rated static load of 465kN. This means it can bear large bidirectional axial and radial loads, which is sufficient to meet the heavy - duty requirements under various complex working conditions. Take the mine crusher as an example. During the ore crushing process, the equipment will bear huge impact loads. The 23022 bearing, relying on its strong load - bearing capacity, can stably support the rotor of the crusher, ensuring the efficient and reliable operation of the equipment and greatly reducing the risk of shutdown failures caused by insufficient bearing load - bearing capacity.
3. Speed Performance: Its limiting speed (with grease lubrication) can reach 1500 - 2200r/min, and (with oil lubrication) can reach 2400 - 3000r/min. Different lubrication methods can be flexibly selected according to the actual working environment and working condition requirements. In scenarios with high - speed operation and high heat dissipation requirements, such as the spindle transmission system of some precision machine tools, oil lubrication can effectively take away heat, reduce friction, ensure the stable operation of the 23022 bearing at high speeds, and maintain the high - precision machining performance of the machine tool. While in equipment with higher requirements for the convenience of lubrication maintenance and relatively low speed, grease lubrication can exert its advantages of good sealing performance and simple maintenance.

The 23022 bearing is usually made of high - quality bearing steel, such as high - carbon chromium bearing steel GCr15. This type of steel has high hardness, high strength, good wear resistance, and fatigue resistance, which can meet the usage requirements of the bearing under long - term heavy - duty and high - speed operation conditions. In the manufacturing process, strict adherence to high - precision processing technology standards is followed. Every link from forging, turning, and grinding of raw materials to heat treatment and assembly is carefully controlled. Advanced grinding technology ensures high precision and low roughness of the raceway and roller surfaces, making the bearing run more smoothly, reducing vibration and noise. Precise heat treatment technology further improves the comprehensive mechanical properties of the steel, enhances the hardness and toughness of the bearing, and prolongs its service life.

1. Industrial Field: In steel mill metallurgical equipment, such as continuous casters and rolling mills, the 23022 bearing needs to bear huge rolling forces and alternating loads. Its high load - bearing capacity and self - aligning performance ensure the continuous and stable operation of the equipment and improve production efficiency. In glass manufacturing industry, equipment such as glass melting furnaces and annealing furnaces work in high - temperature environments, and the shafting is prone to deformation. The 23022 bearing can adapt to such harsh working conditions, ensure the normal operation of the equipment, and ensure the stable quality of glass products. In addition, it is also widely used in industrial machinery such as blast furnace equipment and painting equipment.
2. Mining Machinery: Mining conveyors, transmission devices, and other equipment work in harsh environments for a long time. When conveying materials, they will cause large impact and wear on the bearings. The 23022 bearing, with its strong and durable characteristics, can effectively resist these adverse factors and ensure the smooth transportation of mine materials. At the same time, in key equipment such as crushers and screening machines, the 23022 bearing also plays an important role, providing reliable power support for mining and ore processing.
3. Power Equipment: In power equipment such as boiler fans, vacuum equipment, and motors, the 23022 bearing needs to run stably under different speed and load conditions. Its good speed performance and load - bearing capacity ensure that the fan can efficiently transport gas, the vacuum equipment can maintain a stable vacuum degree, and the motor can achieve reliable power output. In the field of wind power equipment, the 23022 bearing is applied to key parts such as the main shaft, yaw, and pitch systems of wind turbines. In complex outdoor environments, it bears huge loads and frequent variable loads. Its reliable performance provides a solid guarantee for the efficient and stable operation of wind power generation, contributing to the continuous production of clean energy.
4. Machine Tool Equipment: Machine tools have extremely high requirements for precision and stability. The high - precision manufacturing process and good self - aligning performance of the 23022 bearing enable it to meet the operation requirements of key components such as machine tool spindles. During processing, it ensures the precise relative movement between the tool and the workpiece, thereby ensuring processing accuracy and improving product quality. It is widely used in various machine tools such as lathes, milling machines, and grinders.
5. Engineering Machinery and Agricultural Machinery: In terms of engineering machinery, such as excavators and loaders, various components of the equipment will bear strong impact and vibration during operation. The high reliability and strong load - bearing capacity of the 23022 bearing enable it to adapt to such harsh working conditions and ensure the efficient operation of engineering machinery. In the field of agricultural machinery, equipment such as seeders and harvesters work in complex and changeable field environments. The 23022 bearing can reliably support the operating components of the equipment, ensure the smooth progress of agricultural production, and provide strong support for agricultural modernization.
