4306 ATN9 Bearing Product Overview & Core Advantages
The 4306 ATN9 is a double row angular contact ball bearing engineered for applications demanding high rigidity and the ability to handle combined loads. Its metric design features a 30 mm bore and compact 27 mm width, making it an ideal solution for space-constrained, high-performance assemblies. This precision bearing is characterized by its open design, facilitating direct lubrication, and is built with a Nylon cage (TN9) that contributes to its high limiting speed of 16,000 rpm. It is designed to provide reliable operation and long service life in demanding industrial environments.
4306 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| A | Standard contact angle (typically 30°) | Optimized for handling significant combined radial and axial loads. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced | Enables quieter operation, lower friction, and contributes to the high limiting speed. |
4306 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior rigidity and stability compared to single row bearings, enabling it to support substantial radial dynamic load ratings (9225 lbf) and combined loads from multiple directions.
- Optimized for High-Speed Operation: The lightweight and robust Nylon TN9 cage minimizes centrifugal forces and friction, directly supporting the bearing's high limiting speed.
- Precision & Reliability: Manufactured to ABEC-1 tolerance class with a controlled C0 radial internal clearance, ensuring consistent performance and smooth rotation. The open seal type allows for customized lubrication schemes to match specific application needs.
- Durable Material Construction: Rings and balls made from Chrome Steel provide excellent wear resistance and durability for a long operational lifespan.
4306 ATN9 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery requiring robust performance, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
