1306 ETN9/C3 Bearing Product Overview & Core Advantages
The 1306 ETN9/C3 is a double row angular contact ball bearing designed for demanding applications requiring high precision and reliability. This precision bearing excels at simultaneously handling combined loads, including significant radial loads and bidirectional axial loads. Its compact design and robust construction deliver high rigidity, making it an ideal solution for high-performance machinery where space constraints and operational stability are critical.
1306 ETN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| ETN9 | Indicates a Nylon cage and likely a specific internal design optimized for high-speed operation. | Contributes to lower friction, lower noise, and excellent high-speed performance. |
| C3 | Specifies a greater radial internal clearance than the standard C0 group. | Accommodates thermal expansion in applications with high operating temperatures or heavy loads, preventing premature failure. |
1306 ETN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior high rigidity and stability compared to single row bearings. This design enables the bearing to effectively support substantial combined loads (radial and axial) from both directions.
- High-Speed Performance: The lightweight Nylon cage (ETN9) reduces centrifugal forces, allowing for a higher limiting speed of 13,000 rpm. This makes it a capable high-speed bearing for demanding rotational applications.
- Optimized Material & Lubrication: Manufactured from high-grade Chrome Steel for both rings and balls, ensuring durability and long service life. The bearing comes pre-lubricated for immediate operation.
- Precision Dimensions: Manufactured with tight tolerances on the bore diameter (30 mm), outside diameter (72 mm), and width (19 mm), ensuring precise fit and reliable performance in precision assemblies.
1306 ETN9/C3 Bearing Typical Application Areas
The 1306 ETN9/C3 is engineered for high-performance applications across various industries, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
