Industrial Super Low Friction Bearings High Precision Self Aligning Ball Bearing 1307

1307 Self-Aligning Ball Bearing: High Performance, Low Friction For Industry​

I. Basic Overview​

The 1307 self-aligning ball bearing, as a key component in the field of mechanical transmission, plays an indispensable role in numerous industrial equipment. Its design aims to solve the alignment problems that may occur during the installation and operation of the shafting. With its unique structure, it achieves efficient operation and significantly improves the stability and reliability of the equipment.​

II. Structural Design​

1. Cooperation of Double-row Balls and Spherical Raceways: The bearing has two rows of steel balls. The outer ring is provided with a common precision spherical raceway, and the inner ring is equipped with two continuous deep groove raceways. This exquisite design endows the bearing with excellent self-aligning ability, which can effectively cope with the angular misalignment of the shaft relative to the bearing housing caused by the shaft's own deflection during operation or equipment installation errors. Even in complex working conditions, the bearing can ensure the stable operation of the shafting, reduce additional stress and wear caused by misalignment, and prolong the overall service life of the equipment.​

2. Cage Design: It usually adopts an injection-molded nylon 6,6 snap-type cage (TN9 type), which is guided by rolling elements. Nylon material has good wear resistance, self-lubrication and low weight. While ensuring the stable operation of all internal components of the bearing, it can also reduce energy loss and improve the performance of the bearing at high speeds. In addition, the cage can accurately guide the movement of the steel balls, ensuring that the steel balls are evenly distributed in the raceway, effectively avoiding collisions and jams between the steel balls, and further improving the running accuracy and stability of the bearing.​

IV. Performance Advantages​

1. Excellent High-speed Performance: Due to the small number of contact points between the steel balls and the inner and outer ring raceways, the rolling resistance is small, and the heat generated during high-speed operation is extremely low. For example, when the reference speed can reach 16000r/min, the bearing can still maintain stable operation, and the temperature rise is controlled within a reasonable range, which greatly reduces problems such as material performance degradation and lubrication failure caused by high temperature. It is suitable for equipment with high speed requirements, such as transmission systems of high-speed motors and precision machine tool spindles.​

2. Excellent Light Load Performance: For light load conditions, the 1307 self-aligning ball bearing can achieve efficient transmission with its low friction characteristics. Even when bearing a small load, the steel balls can roll smoothly in the raceway, effectively avoiding the slipping of rolling elements caused by too light load, ensuring stable and accurate operation of the equipment. It performs well in light-load equipment such as spinning machines of textile machinery and light conveyor belts in automated production lines.​

3. Low Friction Operation: The unique structure and high-quality materials make the friction at the contact points significantly reduced when the steel balls roll in the raceway. Low friction not only helps reduce equipment energy consumption and improve energy utilization efficiency, but also reduces wear and prolongs the service life of the bearing. Tests show that compared with some similar bearings, the friction coefficient of the 1307 self-aligning ball bearing can be reduced by [X]% under the same working conditions, effectively reducing energy loss during equipment operation.​

4. Good Self-aligning Ability: It can withstand static and dynamic misalignment, allowing a certain angular deviation of the shaft relative to the bearing housing. Generally, the allowable angular misalignment range is [specific angle range]. In practical applications, when the shaft is deflected or slightly deviated due to installation, the bearing can automatically adjust to ensure the normal operation of the shafting, reduce the risk of equipment failure caused by misalignment, and improve 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, fatigue caused by long-term operation and other factors. The 1307 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 the uniform spinning of yarn and high-quality production of fabrics, effectively reduce downtime caused by equipment failures, and improve 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 1307 self-aligning ball bearing is applied to components such as the transmission system of tractors and the conveying device of combine harvesters, it can adapt to the misalignment of the shafting under complex working conditions, bear a certain impact load, ensure the stable operation of agricultural machinery in harsh environments, and help agricultural production proceed smoothly.​

3. Conveying Equipment: Such as belt conveyors, chain conveyors, etc. During long-distance material conveying, the transmission shaft is prone to deviation due to installation errors, equipment deformation and uneven material distribution. The 1307 self-aligning ball bearing can automatically compensate for the misalignment of the shaft, making the conveying equipment run more smoothly, reducing problems such as conveyor belt deviation and chain jamming, improving material conveying efficiency, and reducing equipment maintenance costs.​

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 its advantages of excellent high-speed performance and low friction, it can reduce motor operation noise, improve the electric energy conversion efficiency of the motor, and prolong the service life of the motor. It is widely used in small drive motors in household appliances (such as fans, washing machines) and office equipment (such as printers, copiers).
