3306 ATN9 Bearing Product Overview & Core Advantages
The 3306 ATN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. Engineered to simultaneously handle significant combined loads (radial and axial loads from both directions), its compact design offers a robust solution in a constrained space. Manufactured to a P6 (ABEC-3) tolerance class, this bearing delivers exceptional running accuracy and is pre-lubricated for immediate use, making it ideal for demanding industrial environments.
3306 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 3306 | Standard bore diameter (30 mm) & dimension series | Defines the core bearing dimensions. |
| A | 30° contact angle | Optimized for high axial load capacity. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced | Enables quieter operation, lower friction, and is ideal for high-speed performance. |
3306 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide superior high rigidity, enabling the bearing to withstand heavy combined loads without significant deflection.
High-Speed Performance: The lightweight TN9 cage reduces centrifugal forces, contributing to a high limiting speed of 9,000 rpm. This makes it a capable high-speed bearing.
Precision & Reliability: Manufactured from high-grade chrome steel and held to a P6 tolerance class, this precision bearing ensures smooth, accurate, and consistent operation.
Ready-to-Use: The bearing is pre-lubricated, simplifying installation and providing immediate protection upon startup.
