The 1315 self-aligning ball bearing occupies an important position in mechanical transmission systems. With its unique design and excellent performance, it provides solid reliability for the stable operation of various equipment. It effectively handles alignment problems during installation and operation, automatically adjusting angular deviation to ensure stable and efficient equipment performance. Widely used in industrial production, agricultural machinery, and transportation industries.
Structural Design
Double-row Steel Balls and Spherical Raceways: Features two rows of high-precision steel balls with a common spherical raceway in the outer ring and continuous deep groove raceways in the inner ring. This design provides exceptional self-aligning capability, automatically adjusting to shaft deflection or installation errors to maintain smooth shaft operation.
Cage Construction: Available with steel plate stamping cages for high-load conditions or injection-molded nylon 6,6 snap-type cages (TN9 type). Steel cages offer high strength and wear resistance, while nylon cages provide excellent self-lubrication, reduced weight, and improved high-speed performance with quieter operation.

Performance Advantages
High-Speed Stability: Minimal contact points between balls and raceways result in low rolling resistance and negligible heat generation. Capable of stable operation at reference speeds up to 8000r/min with controlled temperature rise.
Light Load Performance: Maintains efficient transmission under light load conditions, preventing rolling element slippage and ensuring stable equipment operation.
Low Friction Operation: Unique design and quality materials minimize friction at contact points, reducing energy consumption and wear while extending bearing service life.
Self-Aligning Capability: Accommodates static and dynamic misalignment with angular deviation range of 1° to 2.5°, automatically adjusting to shaft deflection and installation errors.
Application Fields
Textile Machinery: Ensures stable operation of spindles and rollers, maintaining yarn uniformity and fabric quality while reducing downtime.
Agricultural Machinery: Withstands complex operating conditions in tractors and combine harvesters, adapting to shaft misalignment and impact loads.
Conveying Equipment: Automatically compensates for shaft misalignment in belt and chain conveyors, improving operational smoothness and reducing maintenance costs.
Small Motors: Handles vibration and misalignment in household appliances and office equipment, reducing noise and improving electrical efficiency.
