1305 ETN9 Bearing Product Overview & Core Advantages
The 1305 ETN9 is a double row angular contact ball bearing designed for applications demanding high rigidity and the ability to handle combined loads. Its compact bearing dimensions (25mm bore, 62mm OD, 17mm width) and metric design make it an ideal precision bearing for space-constrained, high-performance machinery. The bearing is pre-lubricated and features a nylon cage (TN9), contributing to its suitability for high-speed operation up to 15,000 rpm, while maintaining reliable performance across a wide temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1305 | Standard bearing series designation, indicating the basic size (25mm bore, 62mm OD). |
| E | Optimized internal design for enhanced load capacity and performance. |
| TN9 | Indicates a cage made of Nylon (Polyamide 66), which is lightweight and promotes smooth operation at high speeds with reduced friction. |
1305 ETN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to support significant radial loads (4275 lbf dynamic, 1215 lbf static) and moderate axial loads in both directions.
- High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces and ensures stable operation, allowing the bearing to achieve a high limiting speed of 15,000 rpm.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and consistent performance. The tight dimensional tolerances ensure precise fit and alignment in demanding applications.
- Ready-to-Use: The bearing comes pre-lubricated, facilitating easy installation and immediate operation without the need for initial re-lubrication.
1305 ETN9 Bearing Typical Application Areas
The 1305 ETN9 is engineered for high-performance applications across various industries, including:
- Electric Motor Spindles
- Precision Gearboxes
- Industrial Pumps and Compressors
