4214 ATN9 Bearing Product Overview & Core Advantages
The 4214 ATN9 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance. This precision bearing excels at handling combined loads, simultaneously supporting significant radial loads and axial loads in both directions. Its compact double-row design offers a space-saving solution, making it ideal for high-precision machinery and equipment where stability and accuracy are paramount. Manufactured with chrome steel rings and balls, it ensures durability and consistent operation.
4214 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 4214 | Standard bore diameter (70 mm), outside diameter (125 mm), and width (31 mm) designation. |
| A | Contact angle of 30°, optimized for supporting combined loads. |
| TN9 | Nylon (polyamide) cage, which contributes to lower friction, quieter operation, and is suitable for higher speeds. |
4214 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to handle substantial combined loads (radial and bidirectional axial loads) effectively, ensuring stable shaft support.
- High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces, allowing for a high limiting speed of 8,000 rpm. The open design facilitates efficient lubrication management.
- Precision & Accuracy: Manufactured to ABEC-1 tolerance class with a C0 radial internal clearance (0.01mm to 0.03mm), this bearing delivers consistent and precise rotational performance.
- Durability & Material Quality: Components made from chrome steel offer excellent wear resistance and fatigue life, ensuring long-term reliability in demanding applications.
