Precision Double Row Self Aligning Ball Bearing 1313 Customizable

1313 Self-Aligning Ball Bearing: Low Friction & High Performance

I. Product Overview​

The 1313 self-aligning ball bearing is a key component in the field of mechanical transmission. With its unique design and excellent performance, it provides a solid guarantee for the stable operation of various mechanical equipment. This bearing has an excellent self-aligning function, which can effectively deal with the alignment problems occurring during the installation and operation of the shafting. By automatically correcting angular deviations, it ensures the efficient and reliable operation of the equipment. It is widely used in many industries such as industrial manufacturing, agricultural machinery, and material transportation, and has become an important component to ensure the smooth operation of mechanical equipment.​

II. Structural Design​

1. Exquisite Cooperation of Double-row Steel Balls and Spherical Raceways: The 1313 self-aligning ball bearing is precisely assembled with two rows of high-quality steel balls inside. The outer ring is provided with an accurate common spherical raceway, and the inner ring is equipped with two continuous and smooth deep groove raceways. This sophisticated structure endows the bearing with strong self-aligning ability. In actual working conditions, when the shaft is deformed or there is an equipment installation error, resulting in angular misalignment between the shaft and the bearing housing, the bearing can quickly and automatically adjust to maintain the stable operation of the shafting. For example, in some large motor equipment, the motor rotor has a large mass, and the shaft is prone to slight deflection during operation. The 1313 self-aligning ball bearing can easily cope with this, greatly reducing the additional stress and wear caused by misalignment, and significantly prolonging the overall service life of the equipment.​

2. Elaborate Construction of Cage: The bearing usually adopts a steel plate stamping cage or an injection-molded nylon 6,6 snap-type cage (TN9 type). The steel plate stamping cage has high strength and good wear resistance. Under high-load working conditions, it can stably guide the movement of steel balls, ensure that the steel balls are evenly distributed in the raceway, avoid collisions and jams between steel balls, and ensure the stability and reliability of the bearing operation. The nylon 6,6 snap-type cage (TN9 type) is guided by rolling elements. Nylon material has good self-lubrication, wear resistance and low weight. While ensuring the coordinated and stable operation of all internal components of the bearing, it can effectively reduce energy loss, especially at high speeds, which can significantly improve the bearing performance and make the equipment run more smoothly and quietly.​

IV. Performance Advantages​

1. Excellent Stability at High-speed Operation: The 1313 self-aligning ball bearing has few contact points between the steel balls and the inner and outer ring raceways, resulting in extremely low rolling resistance and little heat generated during high-speed operation. Taking the reference speed of [X]r/min as an example, at this speed, the bearing can still maintain stable operation, and the temperature rise is strictly controlled within a reasonable range. This feature greatly reduces common problems such as material performance degradation and lubrication failure caused by high temperature, making it an ideal choice for transmission systems of equipment with strict speed requirements such as high-speed motors and precision machine tool spindles.​

2. Excellent Performance Under Light Load Conditions: In the face of light load conditions, the 1313 self-aligning ball bearing achieves efficient transmission with its own low friction characteristics. Even under small loads, the steel balls can roll smoothly in the raceway, effectively avoiding rolling element slipping caused by too light load, and ensuring stable and accurate operation of the equipment. In light-load equipment such as spinning machines of textile machinery and light conveyor belts in automated production lines, the advantages of this bearing are fully demonstrated, ensuring efficient and stable operation of the equipment.​

3. Low Friction Operation, Energy-saving and Durable: The unique structural design combined with high-quality materials greatly reduces the friction at the contact points when the steel balls roll in the raceway. The low friction characteristic not only helps to reduce equipment energy consumption and improve energy utilization efficiency, but also significantly reduces wear, effectively extending the service life of the bearing. Tests show that compared with some similar bearings, under the same working conditions, the friction coefficient of the 1313 self-aligning ball bearing can be reduced by [X]%, which effectively reduces energy loss during equipment operation and saves operating costs for enterprises.​

4. Strong Self-aligning Ability: The bearing can easily withstand static and dynamic misalignment, allowing a certain angular deviation of the shaft relative to the bearing housing. The general allowable angular misalignment range is between 1° and 2.5°. In practical applications, once the shaft is deflected or there is a slight deviation due to installation, the bearing can quickly and automatically adjust to ensure the normal operation of the shafting, greatly reducing the risk of equipment failure caused by misalignment, and effectively improving the stability and reliability of equipment operation.​

V. Application Fields​

1. Textile Machinery: In the textile production process, the shafting of various equipment is prone to misalignment due to mechanical vibration, long-term operation fatigue and other factors. The 1313 self-aligning ball bearing, with its excellent self-aligning ability and low friction characteristics, can ensure the stable operation of key components such as spindles and rollers of textile machinery, ensure uniform yarn spinning and high-quality fabric production, effectively reduce downtime caused by equipment failures, improve production efficiency, and help textile enterprises improve product quality and production efficiency.​

2. Agricultural Machinery: The agricultural operation environment is complex, and equipment often faces bumpy, vibration and uneven forces caused by different soils. When the 1313 self-aligning ball bearing is applied to components such as tractor transmission systems and combine harvester conveying devices, it can flexibly adapt to the misalignment of the shafting under complex working conditions, and at the same time bear a certain impact load, ensuring the stable operation of agricultural machinery in harsh environments and providing strong support for the smooth progress of agricultural production.​

3. Conveying Equipment: Such as belt conveyors, chain conveyors, etc. In long-distance material conveying, the transmission shaft is prone to deviation due to installation errors, equipment deformation and uneven material distribution. The 1313 self-aligning ball bearing can automatically compensate for shaft misalignment, making the conveying equipment run more smoothly, reducing problems such as conveyor belt deviation and chain jamming, improving material conveying efficiency, reducing equipment maintenance costs, and ensuring efficient and smooth logistics transportation.​

4. Small Motors: In various small motors, the bearing can effectively deal with vibration and misalignment caused by rotor imbalance, shafting installation deviation and other factors during motor operation. With the advantages of good high-speed performance and low friction, it can reduce motor operation noise, improve motor energy conversion efficiency, and extend motor service life. It is widely used in small drive motors of household appliances (such as fans, washing machines) and office equipment (such as printers, copiers), improving the performance and reliability of these equipment.
