4310 ATN9 Bearing Product Overview & Core Advantages
The 4310 ATN9 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance. This precision bearing excels at supporting combined loads, simultaneously managing significant radial forces and axial loads in both directions. Its compact bearing dimensions (50mm bore, 110mm OD, 40mm width) and robust double-row construction make it an ideal choice for high-precision machinery where space constraints and operational reliability are critical. Manufactured to ABEC-1 tolerance standards, it ensures consistent performance and long service life.
4310 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Designates a specific internal design and contact angle optimized for combined load carrying capacity. |
| TN9 | Indicates a Nylon (Polyamide) cage. This lightweight cage contributes to lower friction, lower operating temperatures, and is ideal for high-speed operation. |
4310 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity: The double row design provides superior radial and axial stiffness, minimizing deflection under load and ensuring precise shaft positioning.
- Load Capacity: Engineered to handle substantial combined loads (radial and bidirectional axial), with a dynamic load rating of 18428 lbf and a static load rating of 15638 lbf.
- High-Speed Performance: The lightweight TN9 nylon cage allows for a limiting speed of 10,000 rpm, reducing centrifugal forces and enabling smooth operation at high velocities.
- Precision & Reliability: Manufactured from Chrome Steel with ABEC-1 precision tolerances and a standard C0 radial internal clearance, ensuring consistent performance and interchangeability.
