Self Aligning Double Row Ball Bearings Low Friction 1309 Bearing For Textile Machinery

The 1309 self-aligning ball bearing is an indispensable key component in mechanical transmission systems. With its ingenious design and excellent performance, it provides a solid foundation for the reliable operation of various mechanical equipment.

This bearing features a unique self-aligning function that effectively addresses alignment problems occurring during shaft installation and operation. By automatically correcting angular deviations, it ensures stable and efficient equipment operation. Widely used in industrial manufacturing, agricultural production, and material transportation, it has become a powerful guarantee for smooth mechanical equipment operation.

• Cooperative Operation of Double-row Steel Balls and Spherical Raceways: The 1309 bearing is precisely equipped with two rows of high-quality steel balls. The outer ring features a precise common spherical raceway, while the inner ring has two continuous smooth deep groove raceways. This design provides strong self-aligning ability to handle shaft deflection from deformation or installation errors.
• Exquisite Craftsmanship of Cage: Typically uses steel plate stamping cages or injection-molded nylon 6,6 snap-type cages (TN9 type). Steel cages offer high strength and wear resistance for high-load conditions, while nylon cages provide excellent self-lubrication, reduced weight, and improved high-speed performance with lower noise.

Actual weight may vary due to manufacturing process and material differences.

• Good Stability at High-speed Operation: Minimal contact points between steel balls and raceways result in extremely low rolling resistance. Reference speed of 12000r/min with controlled temperature rise, making it ideal for high-speed motors and precision machine tool spindles.
• Excellent Performance Under Light Load Conditions: Low friction characteristics ensure efficient transmission even under small loads, preventing rolling element slippage. Ideal for textile machinery spinning machines and light conveyor belts.
• Low Friction Operation, Energy-saving and Durable: Unique structural design and quality materials reduce friction at contact points, lowering energy consumption and extending bearing life.
• Strong Self-aligning Ability: Withstands static and dynamic misalignment with angular deviation range of 1° to 2.5°. Automatically adjusts to shaft deflection or installation deviations, reducing equipment failure risk.

• Textile Machinery: Ensures stable operation of spindles and rollers, maintaining uniform yarn spinning and high-quality fabric production while reducing downtime.
• Agricultural Machinery: Adapts to shaft misalignment in complex conditions for tractor transmission systems and combine harvester conveying devices, withstanding impact loads in harsh environments.
• Conveying Equipment: Automatically compensates for shaft misalignment in belt and chain conveyors, reducing belt deviation and chain jamming while improving material conveying efficiency.
• Small Motors: Addresses vibration and misalignment in small drive motors for household appliances and office equipment, reducing noise and improving electrical conversion efficiency.
