1309 ETN9 Bearing Product Overview & Core Advantages
The 1309 ETN9 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing excels at handling significant combined loads, supporting both radial forces and bidirectional axial loads simultaneously. Its compact bearing dimensions (45 mm bore, 100 mm OD, 25 mm width) and robust construction deliver high rigidity and operational stability, making it an ideal choice for high-reliability machinery requiring precise shaft guidance and long service life.
1309 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| E | Optimized internal design for enhanced load capacity and reduced noise/vibration levels. |
| TN9 | Indicates a Nylon (Polyamide) cage, which contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
1309 ETN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to withstand substantial combined loads and moment loads effectively.
- High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces and ensures stable operation at the high limiting speed of 8,500 rpm. The open design facilitates efficient lubrication management.
- Material & Durability: Manufactured from high-grade Chrome Steel for both rings and balls, ensuring excellent wear resistance and long-term dimensional stability under load.
- Precision & Reliability: Features tight dimensional tolerances for bore, outside diameter, and width, guaranteeing precise fit and consistent performance in precision assemblies.
1309 ETN9 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring robust performance and high reliability, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
