1201 ETN9 Bearing Product Overview & Core Advantages
The 1201 ETN9 is a double row angular contact ball bearing designed for high-precision applications requiring robust performance. This metric bearing excels in handling combined radial and axial loads simultaneously, making it ideal for compact spaces demanding high rigidity and reliable operation. Its optimized internal geometry and nylon cage (TN9) contribute to smooth operation and extended service life in demanding industrial environments.
1201 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1201 | Standard bearing designation indicating a 12 mm bore diameter, 32 mm outside diameter, and 10 mm width. |
| E | Optimized internal design for enhanced load capacity and performance. |
| TN9 | Polyamide (Nylon) cage, glass fiber reinforced. Enables high-speed operation, low friction, and quiet running. |
1201 ETN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to support significant combined radial and axial loads from both directions, ensuring stable performance under complex loading conditions.
- High-Speed Performance: The lightweight and robust TN9 nylon cage minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 32,000 rpm, making it suitable for demanding high-speed applications.
- Precision & Reliability: Manufactured from high-grade chrome steel with tight dimensional tolerances, this bearing ensures high running accuracy and consistent performance in precision machinery.
- Pre-Lubricated: Comes with factory-applied lubrication, ready for immediate installation and initial operation, reducing maintenance requirements.
1201 ETN9 Bearing Typical Application Areas
The 1201 ETN9 is engineered for high-performance use in:
- Electric Motors and Small Spindles
- Precision Gearboxes and Power Tools
- Pumps and Compressors
- Office Automation Equipment and Medical Devices
- Any application requiring a compact double row bearing with excellent speed capability and load handling.
