4201 ATN9 Bearing Product Overview & Core Advantages
The 4201 ATN9 is a metric double row angular contact ball bearing engineered for applications requiring high precision and reliable performance. Its double row construction provides superior rigidity and the capacity to support combined radial and axial loads from both directions simultaneously. Designed with an open configuration and a high-performance Nylon cage (TN9), this bearing is optimized for high-speed operation, making it an ideal component for demanding industrial environments where space is limited and performance is critical.
4201 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 4201 | Standard bearing series designation, indicating bearing dimensions (12mm bore, 32mm OD, 14mm width). |
| A | Signifies a 30° contact angle, optimized for handling significant axial loads. |
| TN9 | Indicates a glass fiber reinforced Nylon cage, which contributes to low friction, quiet operation, and high-speed capability. |
4201 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides a robust support structure, significantly increasing stiffness and enabling the bearing to handle substantial combined radial and axial loads.
- Optimized High-Speed Performance: The lightweight and durable TN9 Nylon cage minimizes centrifugal forces and friction, allowing for a high limiting speed of 36,000 rpm.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with a C0 radial internal clearance, ensuring consistent and precise operation suitable for a wide range of industrial applications.
- Durable Material Construction: Rings and balls made from Chrome Steel provide excellent wear resistance and longevity under demanding conditions.
