4211 ATN9 Bearing Product Overview & Core Advantages
The 4211 ATN9 is a double row angular contact ball bearing engineered for demanding applications requiring high rigidity and reliable performance under combined loads. This precision bearing is designed to accommodate significant radial loads and axial loads in both directions simultaneously. Its compact double-row design provides a high load density in a limited space, making it an ideal high rigidity solution for machinery where shaft deflection must be minimized. Manufactured to ABEC-1 tolerance standards, it ensures consistent operation and is suitable for a wide operating temperature range.
4211 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 4211 | Standard bore diameter code (55 mm) and series designation. |
| A | 30° contact angle, optimized for carrying combined loads. |
| TN9 | Indicates a Nylon (Polyamide) cage, which contributes to lower friction, quieter operation, and is suitable for higher speeds. |
4211 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction significantly increases the bearing's moment stiffness and its ability to handle combined loads (radial and axial). This design provides superior support and stability for shafts, reducing system deflection.
High-Speed Performance: The lightweight TN9 nylon cage ensures excellent guidance of the balls with minimal centrifugal force, allowing for a high limiting speed of 10,000 rpm. The open design facilitates efficient lubrication management.
Precision & Reliability: Manufactured from Chrome Steel and held to ABEC-1 tolerances, this bearing delivers consistent dimensional accuracy and smooth running characteristics. The standard C0 radial internal clearance makes it suitable for a wide range of common industrial applications.
4211 ATN9 Bearing Typical Application Areas
