4208 ATN9 Bearing Product Overview & Core Advantages
The 4208 ATN9 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Its metric design and open construction facilitate effective lubrication management in various operational environments. This bearing excels in providing robust support, capable of handling significant radial loads while offering a compact cross-section. Manufactured to ABEC-1 precision tolerances, it is an ideal component for machinery where consistent performance and dimensional accuracy are critical.
4208 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Designates a specific internal design and contact angle optimized for general double row applications. |
| TN9 | Indicates a glass fiber reinforced nylon cage (Polyamide 6,6). This cage design contributes to lower friction, reduced weight, and is suitable for high-speed operation. |
4208 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior radial stiffness, enabling the bearing to withstand substantial radial loads and moderate axial loads in both directions, making it suitable for combined loading scenarios.
- High-Speed Performance: The lightweight and robust TN9 nylon cage ensures smooth operation and guides the balls effectively, contributing to a high limiting speed of 13,000 rpm.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, and adhering to ABEC-1 tolerance standards, this bearing guarantees consistent performance and long service life in demanding applications.
- Operational Flexibility: The open seal type allows for the application of various lubricants tailored to specific operational needs, while the standard C0 radial internal clearance ensures reliable performance under normal operating conditions and temperatures ranging from -30°C to 110°C.
4208 ATN9 Bearing Typical Application Areas
This bearing is commonly specified in a wide range of industrial machinery, including:
- Industrial Gearboxes and Transmissions
- Electric Motors and Generators
