Product Overview and Core Advantages
The 1309KTN is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This precision bearing features a tapered bore (1:12) and is pre-lubricated for immediate use. Its double row design enables it to support substantial combined loads, including significant radial loads and moderate axial loads in both directions. With its compact dimensions and high load capacity, it is engineered for high-reliability applications where space constraints and performance are critical.

| 1309 | Standard bore diameter code (45 mm) and dimension series |
| K | Tapered bore with a 1:12 ratio |
| TN | Nylon (polyamide) cage, enhancing high-speed capability and reducing friction |
Structural Features and Performance Benefits
- High Rigidity: The double row ball complement and robust construction provide exceptional stiffness, minimizing deflection under load for stable operation.
- Superior Load Capacity: Engineered to handle high radial dynamic load ratings (8775 lbf) and moderate bidirectional axial loads, making it suitable for combined load scenarios.
- High-Speed Performance: The lightweight Nylon (TN) cage reduces centrifugal forces, contributing to a high limiting speed of 8,500 rpm.
- Precision and Reliability: Manufactured from chrome steel with a standard CN radial internal clearance, ensuring consistent performance and long service life in demanding conditions.
- Easy Mounting: The tapered bore (K) allows for precise axial positioning and secure interference fit on adapter sleeves or tapered shafts.
1309KTN Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
