126TN Bearing Product Overview & Core Advantages
The 126TN 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, enabling it to handle significant combined loads, including radial loads and bidirectional axial loads. Its compact dimensions (6mm bore, 19mm OD, 6mm width) and robust construction make it an ideal solution for space-constrained assemblies demanding high rigidity and stable operation.
126TN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 126 | Standard bearing series designation, indicating specific internal geometry and size. |
| T | Indicates a Nylon cage (also known as a polymer or synthetic resin cage). |
| N | Suffix denoting an outer ring snap ring groove (not a snap ring itself). |
126TN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized contact angle provide superior stiffness and enable the bearing to support substantial radial loads and moderate axial loads from both directions.
- High-Speed Capability: The lightweight Nylon cage (TN) ensures smooth operation, reduces centrifugal forces, and contributes to a high limiting speed of 45,000 rpm.
- Precision & Reliability: Manufactured from Chrome Steel with tight dimensional tolerances (bore: -0.008mm to 0) and standard CN radial internal clearance, ensuring consistent performance in precision applications.
- Ready-to-Use: The bearing is pre-lubricated, simplifying installation and providing immediate operation within a wide temperature range of -30°C to 110°C.
126TN Bearing Typical Application Areas
This versatile double row ball bearing is engineered for demanding environments, including:
- Small electric motors and spindles
- Precision instruments and optical devices
- Office automation equipment (e.g., printers, scanners)
- Medical devices and dental handpieces
- Robotic arms and small gearboxes
