Industrial Double Row Self Aligning Roller Bearing 23228 Customizable

Product Specification

I. Highlights of Structural Design

II. Accurate Dimensional Parameters

1. Inner diameter: 140mm, which precisely fits many industrial shaft diameter specifications, ensuring a tight fit with the shafts of various equipment and realizing efficient power transmission.
2. Outer diameter: 250mm, the outer diameter size is carefully calculated and optimally designed to provide sufficient structural strength for the bearing while ensuring good compatibility with external equipment components.
3. Width: 88mm, the reasonable width design ensures the load-carrying capacity of the bearing while taking into account the compactness of the entire equipment, meeting the installation requirements under different space constraints.

III. Excellent Performance Parameters

1. Rated dynamic load: The rated dynamic load of 23228 self-aligning double row roller bearings from different brands varies slightly. For example, the rated dynamic load of NSK's 23228CE4 bearing can reach 835,000N, while some high-quality bearings can exceed 1,000,000N, such as some products reaching 1,040,000N. This means they can stably maintain normal working conditions under the working conditions of high-speed operation of equipment and frequent impact and vibration.
2. Rated static load: It is usually at a high level of around 1,300,000N, enabling the bearing to effectively support the static weight of the equipment during the static or start-up phase of the equipment, preventing permanent deformation caused by overload, and prolonging the overall service life of the bearing and the equipment.
3. Limiting speed: The limiting speed varies under different lubrication conditions. When lubricated with grease, it can generally reach 1100rpm, meeting the equipment operation requirements under most conventional working conditions; when lubricated with oil, the limiting speed can be increased to 1500rpm or even higher. For example, when using oil bath lubrication, in accordance with the ISO 15312 standard, the thermal speed rating can reach 1800min⁻¹. Under a well-designed and strictly controlled forced circulation oil lubrication system, the speed can soar to 2600min⁻¹, adapting to the harsh requirements of high-speed operation equipment.

IV. High-Quality Manufacturing Materials

1. Bearing rings: High-quality bearing steel such as 52100 chromium steel is mostly used. It has high strength and hardness, can effectively resist various stresses borne by the bearing during operation, and has good wear resistance, which greatly prolongs the service life of the bearing rings and ensures the long-term stability of the overall performance of the bearing.
2. Rollers: High-performance materials such as 52100 chromium steel are also used, which are matched with the bearing ring materials to ensure excellent contact and rolling performance between the rollers and the bearing rings, reduce friction and wear during operation, and improve the operating efficiency and reliability of the bearing.
3. Cages: Common materials include steel and brass. The cage plays an important role in the bearing by evenly separating the rollers, guiding the movement of the rollers, and maintaining the stability of the rollers. Cages of different materials are suitable for different working environments and load conditions. For example, under high-speed and light-load working conditions, brass cages are more suitable due to their good wear resistance and self-lubricating performance; while in working scenarios with heavy loads and strong impact, steel cages have more advantages due to their higher strength and rigidity.

V. Diverse Application Fields

1. Metallurgical industry: In the process of steel production, many key equipment such as large rolling mills and continuous casting equipment generate huge vibration and impact during operation and are often in high-temperature environments. The high load-carrying capacity and self-aligning characteristics of the 23228 self-aligning double row roller bearing enable it to operate stably under these harsh working conditions, ensuring the continuity and efficiency of the production process and providing a solid guarantee for the stable production of the metallurgical industry.
2. Mining machinery: Mining equipment such as crushers, ball mills, and belt conveyors face complex working conditions such as heavy loads and severe dust pollution for a long time. The 23228 bearing, with its excellent load-carrying performance, can bear the huge weight and impact force of ores. At the same time, its self-aligning function can effectively deal with the shaft misalignment problem caused by the equipment operating in complex terrain, significantly reducing equipment failure rates and improving mining efficiency.
3. Power industry: Whether it is large steam turbines and generators in thermal power generation or fan main shafts in wind power generation, they have extremely high requirements for the reliability and stability of bearings. The 23228 self-aligning double row roller bearing can provide stable support for power equipment under high-speed and high-load conditions, ensuring the accurate operation of the equipment and guaranteeing the continuous and stable power supply.
4. Engineering machinery: Engineering machinery such as excavators, loaders, and cranes frequently experience drastic changes in load and direction conversion during operation. The 23228 bearing, with its strong load-carrying capacity and good adaptability, can maintain excellent performance under complex and changing working conditions, providing reliable guarantees for the efficient operation of engineering machinery and helping various engineering construction projects proceed smoothly.
