1306K Bearing Product Overview & Core Advantages
The 1306K metric double row angular contact ball bearing represents a precision-engineered solution for applications requiring high rigidity and reliable performance under combined loading conditions. Featuring a tapered bore (1:12) for secure shaft mounting, this bearing is designed to accommodate significant radial loads while maintaining operational stability. Its double row ball construction with a nylon cage ensures smooth operation at limiting speeds up to 13,000 rpm, making it an ideal choice for high-speed precision equipment. Manufactured from chrome steel and pre-lubricated for immediate use, it offers excellent durability in demanding industrial environments.

| K | Tapered bore with 1:12 ratio for precise mounting and higher rigidity |
1306K Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row angular contact configuration provides superior stiffness compared to single row bearings, minimizing deflection under heavy radial loads and moment loads.
Enhanced Load Capacity: With a dynamic load rating of 5062 lbf and static load rating of 1530 lbf, this bearing handles combined radial and axial loads effectively in both directions.
Optimized High-Speed Performance: The nylon cage reduces friction and enables smooth operation at limiting speeds of 13,000 rpm, while the CN radial clearance ensures optimal performance across various operating conditions.
Precision Manufacturing: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.01mm to 0, OD: -0.013mm to 0) for consistent precision bearing performance and extended service life.
