4200 ATN9 Bearing Product Overview & Core Advantages
The 4200 ATN9 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance. This metric bearing features an open design without seals, making it suitable for systems where external lubrication is provided. Its double row construction enables it to support significant combined loads (radial and axial loads simultaneously) while maintaining operational stability. Manufactured with chrome steel rings and balls and a nylon cage, it offers a balanced combination of strength, durability, and smooth operation at moderate to high speeds.
4200 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 4200 | Basic bearing series designation, indicating the size and internal geometry. |
| A | Signifies a 30° contact angle, optimized for carrying higher axial loads. |
| TN9 | Indicates the use of a glass fiber reinforced nylon cage (PA66-GF25). This cage design contributes to lower friction, reduced weight, and allows for higher limiting speeds. |
4200 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides superior rigidity compared to single row bearings, enabling stable support for combined radial and axial loads from both directions.
- High-Speed Capability: The lightweight and robust TN9 nylon cage minimizes centrifugal forces and ensures smooth operation, contributing to the bearing's high limiting speed of 40,000 rpm.
- Precision & Reliability: Manufactured to ABEC-1 tolerance class with a standard C0 radial internal clearance, this bearing ensures consistent performance and interchangeability in precision assemblies.
- Material Quality: Components made from high-grade chrome steel provide excellent wear resistance and fatigue life, while the cage material is suitable for a wide temperature range from -30°C to 110°C.
4200 ATN9 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for a variety of industrial applications where compact design, high rigidity, and the ability to handle complex loads are critical. Key sectors include:
- Electric Motors and Small Spindles
- Precision Gearboxes and Power Transmission Systems
- Pumps, Compressors, and Fans
- Material Handling Equipment
