4206 ATN9 Bearing Product Overview & Core Advantages
The 4206 ATN9 is a metric double row angular contact ball bearing engineered for applications requiring high precision and robust performance. This bearing excels at handling combined loads, simultaneously supporting significant radial forces and moderate axial loads in both directions. Its double row design provides enhanced rigidity and load-carrying capacity within a compact cross-section, making it an ideal choice for high-reliability machinery. Manufactured to ABEC-1 precision tolerances, it ensures consistent performance and long service life in demanding operational environments.
4206 ATN9 Bearing Model Code Explained, Specifications & Naming Convention

4206 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing construction, combined with a 30° contact angle, provides exceptional stiffness. This design allows it to handle combined radial and axial loads effectively, making it suitable for applications with complex loading conditions.
High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces and ensures stable operation at the specified limiting speed of 17,000 rpm. This makes the bearing an excellent choice for high-speed spindles and rotating assemblies.
Precision & Reliability: Manufactured from chrome steel and held to ABEC-1 precision standards, the bearing offers dimensional stability and consistent performance. The standard C0 radial internal clearance provides reliable operation under normal load and temperature conditions.
4206 ATN9 Bearing Typical Application Areas
The 4206 ATN9 is ideally suited for a wide range of industrial machinery where precision and reliability are paramount. Key application areas include:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Electric Motors
- Material Handling Equipment
