1205 ETN9/C3 Bearing Product Overview & Core Advantages
The 1205 ETN9/C3 is a metric double row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined radial and axial loads. Its compact design, featuring a 25 mm bore and 15 mm width, provides a space-saving solution without compromising load capacity. The bearing is pre-lubricated and features a nylon cage (ETN9) optimized for high-speed operation up to 18,000 rpm, making it an ideal choice for demanding industrial environments where high rigidity and operational efficiency are critical.
1205 ETN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1205 | Standard bearing designation: 05 series with 25 mm bore diameter. |
| E | Optimized internal design for enhanced load capacity. |
| TN9 | Nylon (polyamide) cage, glass fiber reinforced. Designed for high-speed performance and reduced friction. |
| C3 | Greater than normal radial internal clearance. Suitable for applications with thermal expansion or where interference fits are used. |
1205 ETN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness and enables the bearing to support significant combined radial and axial loads simultaneously from both directions.
- Optimized High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces, reduces friction, and contributes to the bearing's high limiting speed of 18,000 rpm.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, ensuring high durability and consistent performance. The C3 clearance offers operational flexibility in applications prone to thermal expansion.
- Ready-to-Install: The bearing comes pre-lubricated, facilitating easy installation and immediate operation.
1205 ETN9/C3 Bearing Typical Application Areas
This double row angular contact ball bearing is widely used in:
- Electric Motors and Small Spindles
- Precision Gearboxes and Power Transmission Systems
- Pumps and Compressors
- Material Handling Equipment
- Various industrial machinery requiring high-speed and high-rigidity support.
