3202 ATN9 Bearing Product Overview & Core Advantages
The 3202 ATN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at simultaneously handling combined loads, including significant radial and bidirectional axial loads. Its compact design, featuring a 15 mm bore and 35 mm outside diameter, provides a space-saving solution. Manufactured to a P6 (ABEC-3) tolerance class and equipped with a Nylon cage, it is engineered for smooth operation and is pre-lubricated for immediate use, making it ideal for demanding industrial environments.
Model Code Breakdown
| Suffix | Technical Meaning |
|---|---|
| A | Designates a specific internal design with a 30° contact angle, optimized for carrying high axial loads. |
| TN9 | Indicates the cage is made of Nylon (Polyamide 66), which contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
3202 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior rigidity and stability compared to single row bearings, enabling it to support substantial combined radial and axial loads from both directions. This makes it exceptionally robust for applications with complex loading conditions.
High-Speed Performance: The lightweight Nylon (TN9) cage reduces centrifugal forces, minimizes friction, and allows for a higher limiting speed of 18,000 rpm. This makes the 3202 ATN9 an excellent choice for high-speed spindles and rotating assemblies.
Precision & Reliability: Manufactured to P6 tolerance with chrome steel rings and balls, this bearing ensures consistent running accuracy and long service life. The open seal type allows for easy re-lubrication in service, while the standard pre-lubrication ensures immediate operational readiness.
3202 ATN9 Bearing Typical Application Areas
The 3202 ATN9 is ideally suited for a wide range of precision machinery and industrial equipment, including:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Industrial Fans and Blowers
- Medical and Laboratory Equipment
