4217 ATN9 Bearing Product Overview & Core Advantages
The 4217 ATN9 is a double row angular contact ball bearing engineered for demanding applications requiring robust radial load capacity and compact design. This precision bearing features an open construction, allowing for optimized lubrication management. Manufactured to ABEC-1 tolerance class, it delivers reliable performance and high operational consistency, making it an ideal component for industrial machinery where space constraints and high rigidity are critical factors.
4217 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 4217 | Standard bearing series designation, indicating the basic dimensions: 85mm bore, 150mm OD, 36mm width. |
| A | Signifies a 30-degree contact angle, optimized for handling significant combined loads. |
| TN9 | Indicates a glass fiber reinforced nylon cage (Polyamide 66). This design is lightweight, promotes lower friction, and is excellent for high-speed operation. |
4217 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial stiffness and enables the bearing to support substantial radial dynamic loads up to 21,060 lbf. The 30-degree contact angle further enhances its ability to manage combined loads effectively.
- Optimized High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces, contributing to a high limiting speed of 7,000 rpm. This makes the bearing suitable for applications requiring rapid rotation.
- Precision Engineering: Manufactured from chrome steel for both rings and balls, and adhering to ABEC-1 precision standards with a C0 radial internal clearance (0.012mm to 0.036mm), this bearing ensures smooth operation and long service life.
- Operational Versatility: With a wide operating temperature range from -30°C to 110°C, this bearing is suitable for various industrial environments.
4217 ATN9 Bearing Typical Application Areas
This bearing is commonly specified in:
- Industrial Gearboxes and Transmissions
- Material Handling Conveyor Systems
- Agricultural Machinery
- Medium-Duty Pump and Compressor Systems
