3208 ATN9 Bearing Product Overview & Core Advantages
The 3208 ATN9 is a double row angular contact ball bearing engineered for applications demanding high precision and robust performance. This precision bearing is designed to accommodate combined loads—simultaneously handling significant radial loads and axial loads in both directions. Its compact design, featuring optimized bearing dimensions (40mm bore, 80mm OD, 30.2mm width), provides a high-stiffness solution in a confined space. Manufactured to a P6 (ABEC-3) tolerance class, it ensures reliable operation and positional accuracy in high-performance machinery.
3208 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Prefix/Suffix | Technical Meaning |
|---|---|
| 3208 | Standard designation for the bearing series and size. |
| A | Signifies a 30° contact angle, optimized for supporting higher axial loads. |
| TN9 | Indicates the cage is made of Nylon (Polyamide 66), contributing to lower friction, quieter operation, and suitability for high-speed applications. |
3208 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and angular contact design provide superior radial and axial stiffness, enabling the bearing to handle substantial combined loads with minimal deflection.
- High-Speed Performance: The lightweight Nylon TN9 cage reduces centrifugal forces and ensures stable operation at the limiting speed of 8,000 rpm. The open design allows for efficient lubrication management.
- Precision & Reliability: Manufactured from Chrome Steel and held to P6 tolerance, this bearing guarantees consistent performance, long service life, and minimal rotational runout.
- Operational Versatility: Pre-lubricated and capable of operating within a temperature range of -30°C to 110°C, it is ready for installation in a wide array of industrial environments.
