4301 ATN9 Bearing Product Overview & Core Advantages
The 4301 ATN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliable performance. This metric bearing features an open design without seals, making it ideal for controlled environments where maximum speed capability is essential. Its double row construction provides superior rigidity and enables it to handle combined loads (both radial and axial) simultaneously. With its ABEC-1 precision class and optimized internal geometry, it delivers consistent performance in demanding applications.
4301 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 4301 | Basic bearing designation indicating size series and bore diameter |
| A | Contact angle of 30°, optimized for combined load capacity |
| TN9 | Nylon cage (polyamide) for reduced weight and enhanced high-speed performance |
4301 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row ball bearing configuration provides exceptional stiffness, minimizing deflection under load and maintaining precision alignment in critical applications.
Superior Load Capacity: Engineered to handle significant radial dynamic loads (2925 lbf) and axial loads simultaneously, making it suitable for complex loading conditions.
High-Speed Capability: The TN9 nylon cage reduces rotational mass and friction, enabling limiting speeds up to 34,000 rpm while maintaining stability.
Precision Performance: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (C0: 0.003mm to 0.018mm) for consistent operation and minimal vibration.
Material Excellence: Constructed from chrome steel for both rings and balls, ensuring durability and long service life in demanding environments.
