4305 ATN9 Bearing Product Overview & Core Advantages
The 4305 ATN9 is a double row angular contact ball bearing engineered for applications demanding high rigidity and the ability to handle combined loads. Its compact double row design provides superior stability compared to single row bearings, making it ideal for precision machinery requiring reliable performance under significant radial and bidirectional axial forces. Manufactured to ABEC-1 precision standards, this bearing ensures consistent operation in high-performance industrial environments.
4305 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Designates a 30° contact angle, optimized for carrying substantial axial loads. |
| TN9 | Indicates a glass fiber reinforced nylon cage, which contributes to lower friction, quieter operation, and suitability for high-speed applications. |
4305 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides a significantly stiffer support structure than single row bearings, enabling it to withstand heavy combined loads (radial and axial) and moment loads effectively.
- Optimized for High Speeds: The lightweight TN9 nylon cage reduces centrifugal forces, minimizes friction, and allows for a high limiting speed of 18,000 rpm, making it an excellent high-speed bearing.
- Precision Engineering: Built to ABEC-1 tolerance class with a C0 radial internal clearance, this precision bearing ensures smooth, reliable, and vibration-free operation.
- Material Integrity: Components made from high-grade chrome steel offer excellent durability, wear resistance, and a long operational lifespan.
4305 ATN9 Bearing Typical Application Areas
The 4305 ATN9 is ideally suited for a wide range of demanding industrial applications, including:
- Machine Tool Spindles
- Gearboxes and Transmissions
- Industrial Pumps and Compressors
- Precision Agricultural Machinery
- Material Handling Equipment
