2204 ATN9 Bearing Product Overview & Core Advantages
The 2204 ATN9 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Its metric design features a sealed construction with a nylon cage, enabling it to handle significant radial loads while offering excellent operational stability. Pre-lubricated and featuring optimized internal geometry, this precision bearing is engineered for compact installations where space is at a premium and high reliability is essential.
2204 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Designates a specific internal design and contact angle optimized for general combined loads. |
| TN9 | Indicates a glass fiber reinforced nylon cage, contributing to low friction, quiet operation, and suitability for high-speed applications. |
2204 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide superior stiffness, enabling the bearing to support substantial radial dynamic loads (2858 lbf) and static loads (765 lbf).
- Sealed & Lubricated for Long Life: The integral seals protect against contamination and retain the factory-applied lubricant, ensuring consistent performance and offering a maintenance-free solution within its specified temperature range (-30° to 110 °C).
- Optimized for Speed: The lightweight nylon cage (TN9) minimizes centrifugal forces, allowing for a high limiting speed of 10,000 rpm, making it an excellent choice for high-speed rotation.
- Precision Dimensions: Manufactured with tight tolerances on the bore diameter (20 mm), outside diameter (47 mm), and width (18 mm) for precise fit and reliable operation in demanding assemblies.
2204 ATN9 Bearing Typical Application Areas
This bearing is ideally suited for:
- Electric Motor Spindles
- Small Industrial Gearboxes
- Precision Power Tools
- Pumps and Compressors
- Material Handling Equipment
