1308KTN Bearing Product Overview & Core Advantages
The 1308KTN is a double row angular contact ball bearing engineered for high performance in demanding applications. This precision bearing is designed with a 1:12 tapered bore for secure shaft mounting, ensuring exceptional rigidity and alignment. Its double row construction enables it to accommodate significant combined loads, including radial and bidirectional axial loads, making it an ideal choice for applications requiring high reliability and compact design. Pre-lubricated and featuring a nylon cage, it offers smooth operation and is ready for immediate installation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1308 | Standard bearing series designation, indicating the bearing dimensions (40mm bore, 90mm OD). |
| K | Indicates a tapered bore with a 1:12 ratio. |
| TN | Specifies the cage material; TN denotes a molded nylon cage, which is lightweight and contributes to high-speed performance and quiet operation. |
1308KTN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide superior rigidity, enabling the bearing to handle high radial dynamic load ratings of 7605 lbf and significant combined loads.
- Precision Tapered Bore: The 1:12 tapered bore ensures a precise and secure interference fit on the shaft, minimizing inner ring creep and enhancing overall system stability.
- Optimized High-Speed Performance: The lightweight nylon cage (TN) reduces centrifugal forces, lowers friction, and allows for a high limiting speed of 9,500 rpm.
- Ready-to-Use Lubrication: The bearing comes pre-lubricated, facilitating easy installation and providing immediate protection, suitable for a wide temperature range from -30°C to 110°C.
