1302 ETN9 Bearing Product Overview & Core Advantages
The 1302 ETN9 is a double row angular contact ball bearing engineered for applications requiring high precision and reliability. This metric bearing features an open design and is pre-lubricated, enabling it to handle significant radial loads efficiently. Its compact construction, with a 15 mm bore and 42 mm outside diameter, makes it ideal for space-constrained assemblies. The bearing is designed for high-speed operation, with a limiting speed of 24,000 rpm, and operates effectively within a temperature range of -30° to 110°C, making it a robust solution for demanding industrial environments.
1302 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| E | Optimized internal design for enhanced load capacity and performance. |
| TN9 | Polyamide (Nylon) cage, glass fiber reinforced. This cage material contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
1302 ETN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement provides superior high rigidity and enables the bearing to support substantial radial dynamic load ratings of 2430 lbf.
- High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces, which is critical for achieving the high limiting speed of 24,000 rpm.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, ensuring high durability and consistent performance. The tight dimensional tolerances on the bore diameter and outside diameter guarantee precise fit and operation.
- Ready-to-Use: The bearing comes pre-lubricated, facilitating easy installation and immediate operation.
