4213 ATN9 Bearing Product Overview & Core Advantages
The 4213 ATN9 is a double row angular contact ball bearing engineered for applications requiring high radial load capacity and exceptional operational stability. As a metric precision bearing with an open design, it delivers high rigidity and reliable performance in demanding environments. Its double row construction provides robust support, making it ideal for machinery where space constraints and load-bearing requirements are critical. Manufactured to ABEC-1 tolerance standards, this bearing ensures consistent accuracy and is capable of operating within a wide temperature range.
4213 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 4213 | Standard bearing series designation, indicating the bearing dimensions (65mm bore, 120mm OD, 31mm width). |
| A | Signifies a specific contact angle optimized for combined radial and axial loads. |
| TN9 | Indicates a glass fiber reinforced nylon cage, which contributes to high-speed performance, low friction, and reduced weight. |
4213 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design significantly increases radial stiffness and enables the bearing to support substantial radial dynamic loads up to 15,210 lbf, providing stable and precise shaft support.
- Optimized for High Speeds: The lightweight and robust TN9 nylon cage ensures smooth operation and minimizes centrifugal forces, allowing for a limiting speed of 8,500 rpm.
- Precision Engineering: Manufactured from chrome steel for both rings and balls, and built to ABEC-1 precision class, this bearing guarantees consistent performance and long service life.
- Standard Internal Clearance: Features a C0 radial internal clearance (0.008mm to 0.028mm), making it suitable for a wide range of standard applications and operating conditions.
4213 ATN9 Bearing Typical Application Areas
This bearing is ideally suited for a variety of industrial machinery and equipment, including:
- Industrial Gearboxes and Transmission Systems
- Electric Motors and Generators
- Material Handling Equipment such as conveyor pulleys
- General Industrial Machinery requiring robust radial support
