1307KTN Bearing Product Overview & Core Advantages
The 1307KTN is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing features a tapered bore for secure shaft mounting and is pre-lubricated for immediate use. Its core advantage lies in its ability to support significant combined loads (radial and axial) simultaneously, offering a compact, high-rigidity solution. The use of a nylon cage contributes to its suitability for high-speed operation, making it an ideal choice for applications requiring high reliability and precision.
1307KTN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1307 | Standard bearing designation indicating bearing dimensions: 35mm bore, 80mm OD, 21mm width. |
| K | Tapered bore with a conicity of 1:12. |
| TN | Molded nylon cage, glass fiber reinforced, providing excellent high-speed performance and reduced friction. |
1307KTN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide high radial and axial stiffness, enabling the bearing to handle substantial combined loads effectively.
- High-Speed Performance: The lightweight nylon (TN) cage minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 11,000 rpm, making it a true high-speed bearing.
- Precision Tapered Bore: The K-designation tapered bore (1:12) ensures a precise and secure interference fit on a tapered shaft adapter, eliminating inner ring creep and enhancing rotational accuracy.
- Ready-to-Use: The bearing is factory lubricated, simplifying installation and ensuring immediate, reliable operation.
- Standard Internal Clearance: Supplied with a CN group radial internal clearance, suitable for a wide range of common operating conditions.
