127 TN9 Bearing Product Overview & Core Advantages
The 127 TN9 is a metric double row angular contact ball bearing engineered for applications demanding high precision and reliability. Its double row ball construction provides superior rigidity and the ability to support combined loads (radial and axial) simultaneously. Featuring an open design with a Nylon cage (TN9), this bearing is optimized for high-speed operation, offering smooth rotation and low noise. Its compact dimensions and high performance make it an ideal solution for space-constrained, high-performance mechanisms.
127 TN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 127 | Standard bore diameter code, indicating a 7 mm bore. |
| TN9 | Designates a glass-fiber reinforced Nylon cage. This cage material is lightweight, promotes lower friction, and is excellent for high-speed applications. |
127 TN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design significantly increases radial stiffness and enables the bearing to handle substantial combined loads and moment loads, providing stable and precise shaft support.
High-Speed Performance: The lightweight TN9 Nylon cage reduces centrifugal forces, minimizes friction, and allows for a high limiting speed of 40,000 rpm, making it a true high-speed bearing.
Precision & Reliability: Manufactured from Chrome Steel for both rings and balls, this bearing ensures high durability and long service life. The precision bearing dimensions and tight tolerances guarantee consistent performance in demanding applications.
127 TN9 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for a wide range of high-precision and high-speed machinery, including:
- High-speed spindles in machine tools
- Precision gearboxes and transmissions
- Electric motors and fans
- Medical and dental handpieces
- Office automation equipment
