1311 Self Aligning Ball Bearing Low Friction Mining Machinery Bearings Double Row

As a key component in the field of mechanical transmission, the 1311 self-aligning ball bearing provides reliable guarantee for the stable operation of various mechanical equipment with its unique design and excellent performance. This bearing can effectively deal with the alignment problems occurring during the installation and operation of the shafting. By automatically adjusting the angular deviation, it ensures the smooth and efficient operation of the equipment, and is widely used in industrial production, agricultural machinery, transportation and other industries.

1. Exquisite Cooperation of Double-row Steel Balls and Spherical Raceways: The 1311 self-aligning ball bearing is equipped with two rows of high-precision steel balls inside. The outer ring is provided with a precise common spherical raceway, and the inner ring is equipped with two continuous and smooth deep groove raceways. This carefully designed structure endows the bearing with excellent self-aligning ability. In actual working conditions, when the shaft is deflected due to its own deformation or there is an error in equipment installation, resulting in angular misalignment between the shaft and the bearing housing, the bearing can quickly and automatically adjust to keep the shafting running smoothly. For example, in some large motors, due to the large weight of the motor rotor, the shaft is prone to slight deflection during operation. The 1311 self-aligning ball bearing can easily cope with this situation, 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 uses a steel plate stamping cage or an injection-molded nylon 6,6 snap-type cage (TN9 type). If a steel plate stamping cage is adopted, it has high strength and good wear resistance, and can stably guide the movement of steel balls under high-load working conditions, ensuring that the steel balls are evenly distributed in the raceway, avoiding collisions and jams between steel balls, and maintaining 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 excellent self-lubrication, good wear resistance and low weight. While ensuring the stable operation of all internal components of the bearing, it can effectively reduce energy loss, especially at high speeds, which can significantly improve the performance of the bearing and make the equipment run more smoothly and quietly.

1. Strong Stability at High Speeds: The 1311 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. During high-speed operation, the heat generated by the bearing is negligible. Taking the reference speed of 9500r/min as an example, at this speed, the bearing can still maintain a stable operation state, 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 high 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 1311 self-aligning ball bearing achieves efficient transmission with its inherent low friction characteristics. Even when bearing a small load, the steel balls can still roll smoothly in the raceway, effectively avoiding the slipping of rolling elements caused by too light a load, and ensuring that the equipment runs stably and accurately. 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, thereby 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 1311 self-aligning ball bearing can be reduced by [X]%, which effectively reduces the 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 actual application scenarios, 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, effectively improving the stability and reliability of equipment operation, and ensuring the continuous and stable operation of the equipment.

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 1311 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, improve production efficiency, and help textile enterprises improve product quality and production efficiency.
2. Agricultural Machinery: The agricultural operation environment is complex and changeable, and equipment often faces bumpy, vibration and uneven forces caused by different soils. When the 1311 self-aligning ball bearing is applied to components such as the transmission system of tractors and the conveying device of combine harvesters, 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, providing solid support for the smooth progress of agricultural production, and contributing to agricultural harvest.
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 1311 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, 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 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), improving the performance and reliability of these equipment.
