1207 ETN9 Bearing Product Overview & Core Advantages
The 1207 ETN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at handling combined loads, simultaneously supporting substantial radial forces and bidirectional axial loads. Its compact bearing dimensions (35 mm bore, 72 mm OD, 17 mm width) enable space-saving designs. Featuring an open design with a Nylon cage (ETN9) and pre-lubrication, it is engineered for high-speed operation and offers excellent performance within a wide temperature range.
1207 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Standard bore diameter code (35 mm) and dimension series. |
| E | Optimized internal design for enhanced load capacity. |
| TN9 | Cage type designation, indicating a glass fiber reinforced Nylon 66 cage. This contributes to lower friction, quieter operation, and suitability for high speeds. |
1207 ETN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides a rigid support system, significantly increasing the bearing's ability to withstand combined loads (radial and bidirectional axial loads) compared to single row designs.
- Superior High-Speed Performance: The lightweight Nylon TN9 cage reduces centrifugal forces and ensures stable operation at the limiting speed of 13,000 rpm. The pre-lubrication further facilitates smooth high-speed rotation.
- Durable Material Construction: Manufactured from Chrome Steel for both rings and balls, ensuring high durability, wear resistance, and a long operational lifespan under demanding conditions.
- Precision Engineering: Manufactured with tight dimensional tolerances, ensuring precise fit and reliable performance in high-precision applications.
1207 ETN9 Bearing Typical Application Areas
The 1207 ETN9 is ideally suited for a wide range of industrial machinery and precision equipment, including:
- Electric Motors and Small Gearboxes
- Pumps and Compressors
- Material Handling Equipment
- Precision Spindles in various industrial tools
- Agricultural and Automotive auxiliary machinery
