1213KTN Bearing Product Overview & Core Advantages
The 1213KTN is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and precise operation. Featuring a 1:12 tapered bore and open design, this bearing is optimized for secure shaft mounting and efficient performance. Its double row construction provides superior rigidity and stability, making it an ideal solution for machinery demanding high reliability and dimensional accuracy under significant radial loads.
1213KTN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| K | Indicates a tapered bore with a 1:12 ratio, enabling precise interference fit on the shaft for enhanced stability. |
| TN | Signifies a Nylon cage, which contributes to lower friction, quieter operation, and is suitable for higher speeds. |
1213KTN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides excellent resistance to deflection, supporting high radial dynamic load ratings of 7898 lbf. This makes it capable of handling substantial combination loads in demanding applications.
- Precision Tapered Bore: The 1:12 taper allows for a tight, secure fit on a matching tapered shaft adapter, eliminating internal clearance and ensuring maximum power transmission and positional accuracy.
- Optimized High-Speed Performance: The lightweight Nylon (TN) cage reduces centrifugal forces, enabling a limiting speed of 7000 rpm. The standard CN radial internal clearance is well-suited for a wide range of operating conditions.
- Durable Material Construction: Manufactured from Chrome Steel for both rings and balls, ensuring high durability, wear resistance, and a long operational lifespan.
- Pre-Lubricated & Ready for Use: The bearing comes lubricated from the factory, facilitating immediate installation and initial operation.
1213KTN Bearing Typical Application Areas
This bearing is commonly specified in industries and equipment where high radial load capacity and precise shaft location are critical. Key applications include:
- Agricultural Machinery (e.g., gearboxes, conveyor systems)
- Material Handling Equipment
- Industrial Fans and Blowers
- Pump Systems
- Various machinery utilizing tapered shaft adapters for mounting.
