3201 ATN9 Bearing Product Overview & Core Advantages
The 3201 ATN9 is a metric double row angular contact ball bearing engineered for applications requiring high precision and reliable performance. This bearing excels at simultaneously handling combined radial and axial loads from both directions, thanks to its optimized contact angle and double row design. Its compact cross-section and P6 (ABEC-3) tolerance class make it an ideal choice for high-precision machinery where space is limited and operational reliability is critical.
3201 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3201 | Basic bearing designation indicating a metric double row angular contact ball bearing with a 12 mm bore. |
| A | Specifies a 30° contact angle, optimized for supporting significant axial loads. |
| TN9 | Indicates a glass fiber reinforced nylon cage (Polyamide 66). This design contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
3201 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior radial and axial stiffness, enabling stable performance under combined loads. The specified 30° contact angle is particularly effective at managing bidirectional axial thrust.
- High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces, allowing for a high limiting speed of 22,000 rpm. The pre-lubrication ensures smooth operation from startup.
- Precision & Reliability: Manufactured to a P6 tolerance class with tight dimensional controls on the bearing bore and outside diameter, this component guarantees consistent, high-precision rotation.
- Material Integrity: Constructed from hardened chrome steel for rings and balls, ensuring long service life and durability under demanding conditions.
3201 ATN9 Bearing Typical Application Areas
This bearing is designed for high-performance applications, including:
- Machine Tool Spindles
- Precision Gearboxes
- High-Speed Motors and Pumps
- Industrial Automation Equipment
- Medical and Laboratory Instruments
