1202 ETN9/C2 Bearing Product Overview & Core Advantages
The 1202 ETN9/C2 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design and is pre-lubricated for immediate use. Its double row construction provides superior rigidity and enables it to accommodate combined loads (radial and axial loads) simultaneously. With a C2 radial internal clearance and a nylon cage, it is optimized for smooth operation and is suitable for high-speed applications.
1202 ETN9/C2 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| E | Optimized internal design for enhanced load capacity. |
| TN9 | Nylon cage, injection molded, suitable for high speeds and offering low friction and quiet operation. |
| C2 | Radial internal clearance group smaller than normal (CN), suitable for applications requiring precise shaft positioning and where thermal expansion is a consideration. |
1202 ETN9/C2 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides a rigid support system, effectively handling significant radial loads and moderate axial loads in both directions.
- High-Speed Performance: The lightweight nylon cage (TN9) reduces centrifugal forces, minimizes friction, and contributes to a high limiting speed of 28,000 rpm.
- Precision & Longevity: Manufactured from chrome steel for both rings and balls, ensuring high durability and wear resistance. The C2 clearance allows for precise shaft alignment and accommodates operational thermal effects.
- Ready-to-Use: The bearing comes pre-lubricated, simplifying installation and providing immediate, reliable performance.
1202 ETN9/C2 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for a wide range of industrial machinery and precision equipment, including:
- Electric Motors and Small Spindles
- Precision Gearboxes
- Pumps and Compressors
- Office Automation Equipment
- Medical and Dental Handpieces
