1201 ETN9/C2 Bearing Product Overview & Core Advantages
The 1201 ETN9/C2 is a double row angular contact ball bearing designed for applications requiring high precision and reliable performance. This metric bearing features an open design and is pre-lubricated for immediate operation. Its double row construction enables it to support significant radial loads while offering high rigidity. The optimized internal geometry and C2 radial internal clearance make it suitable for precision arrangements where minimal play is required. With a compact design (12mm bore, 32mm OD, 10mm width), it provides an excellent solution for space-constrained applications demanding high rotational accuracy and long service life.
Model Code Detailed Explanation
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 1201 | Basic designation: 12mm bore, 32mm OD, 10mm width | Standard metric dimensions for easy integration |
| E | Optimized internal design | Enhanced load capacity and performance |
| TN9 | Nylon cage, glass fiber reinforced | Excellent high-speed capability, reduced friction |
| C2 | Radial internal clearance smaller than normal | Precision fit for applications requiring minimal play |
1201 ETN9/C2 Bearing Structural Features & Performance Benefits
Double Row Design: The two rows of balls provide high rigidity and stable operation under radial loads, making it ideal for applications where shaft deflection must be minimized.
Nylon Cage (TN9): The glass fiber reinforced nylon cage offers excellent high-speed performance, contributing to the bearing's limiting speed of 32,000 rpm. This material provides good strength-to-weight ratio and operates smoothly with minimal friction.
Precision Engineering: Manufactured from chrome steel for both rings and balls, ensuring high durability and wear resistance. The C2 clearance provides tighter internal tolerances for precision applications.
Pre-lubricated Design: Factory-lubricated for immediate operation, reducing installation time and ensuring proper lubrication from the first rotation.
