1200 ETN9 Bearing Product Overview & Core Advantages
The 1200 ETN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design without seals, optimized for high-speed operation and efficient lubrication distribution. Its compact double row construction provides superior rigidity and the capacity to handle significant combined loads, including radial and axial forces in both directions. The use of a Nylon cage (TN9) contributes to reduced friction and quieter operation at high rotational speeds, making it ideal for demanding industrial environments.
1200 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1200 | Basic bearing series designation, indicating a double row angular contact ball bearing with specific bearing dimensions (10mm bore, 30mm OD, 9mm width). |
| E | Optimized internal design for enhanced load capacity and performance. |
| TN9 | Nylon cage, glass fiber reinforced, suitable for high speeds and offering low weight and excellent sliding properties. |
1200 ETN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides increased contact angles, resulting in exceptional stiffness and the ability to support substantial combined radial and axial loads simultaneously.
- Superior High-Speed Performance: The lightweight TN9 Nylon cage minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 36,000 rpm. The open seal type facilitates efficient lubrication flow and heat dissipation.
- Precision Engineering: Manufactured from Chrome Steel for both rings and balls, ensuring high durability, wear resistance, and consistent performance under load. The tight dimensional tolerances guarantee precise shaft positioning.
- Pre-Lubricated & Ready-to-Use: Comes pre-lubricated for immediate installation and initial operation, suitable for the specified temperature range of -30°C to 110°C.
