The 1208 ETN9 is a metric double row angular contact ball bearing engineered for high-performance applications demanding reliability and precision. This bearing is designed to accommodate significant combined radial and axial loads from both directions, making it an ideal solution for compact arrangements. Its open design, optimized internal geometry, and nylon cage contribute to superior high-speed capabilities and smooth operation, ensuring long service life in demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1208 | Standard bearing series designation, indicating a 40 mm bore, 80 mm OD, and 18 mm width. |
| E | Optimized internal design, typically providing enhanced load capacity and performance. |
| TN9 | Indicates a glass fiber reinforced nylon cage, which is lightweight and ideal for high-speed operation, reducing friction and heat generation. |
1208 ETN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing construction provides a rigid support system, effectively handling combined loads and moment loads. With a dynamic load rating of 4478 lbf and a static load rating of 1564 lbf, it offers robust performance under strenuous conditions.
Superior High-Speed Performance: The TN9 nylon cage is a key contributor to the bearing's high limiting speed of 11,000 rpm. Its lightweight nature minimizes centrifugal forces, ensuring stability and reduced wear at high rotational velocities.
Precision & Reliability: Manufactured from chrome steel for both rings and balls, this bearing ensures high durability and resistance to wear. The precise bearing dimensions and tight tolerances guarantee consistent performance and ease of integration into high-precision assemblies.
