1307 EKTN9 Bearing Product Overview & Core Advantages
The 1307 EKTN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at simultaneously handling combined loads (radial and axial loads in both directions) due to its optimized contact angle and double row design. Its compact bearing dimensions (35mm bore, 80mm OD, 21mm width) and high rigidity make it ideal for space-constrained, high-performance applications. The bearing comes pre-lubricated and features a nylon cage for superior high-speed performance.
1307 EKTN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 1307 | Standard bearing series designation | Defines basic bearing dimensions and capacity |
| EK | Optimized internal design | Enhanced load capacity and high rigidity |
| TN9 | Nylon cage, glass fiber reinforced | Excellent high-speed performance and reduced friction |
1307 EKTN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness and can handle significant combined loads including radial loads and bidirectional axial loads simultaneously. With a dynamic load rating of 5962 lbf and static load rating of 1912 lbf, this bearing delivers reliable performance under demanding conditions.
High-Speed Performance: The TN9 nylon cage ensures optimal performance at high rotational speeds, supporting limiting speeds up to 11,000 rpm. The cage's lightweight construction and excellent sliding properties contribute to reduced friction and heat generation.
Precision Engineering: Manufactured from chrome steel for both rings and balls, this precision bearing maintains dimensional stability and long service life. The open design allows for efficient lubrication management while maintaining tight dimensional tolerances for precise applications.
