126 TN9/W64 Bearing Product Overview & Core Advantages
The 126 TN9/W64 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and precise operation. This precision bearing features an open design and is pre-lubricated, enabling it to handle significant combined loads—both radial and bidirectional axial forces—simultaneously. Its compact dimensions (6 mm bore, 19 mm OD, 6 mm width) make it ideal for space-constrained, high-reliability assemblies where consistent performance is critical.
126 TN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| 126 | Basic bearing series designation |
| TN9 | Nylon cage, offering reduced weight, excellent speed capability, and quiet operation |
| W64 | Specification for the pre-applied lubricant, ensuring optimal performance from initial operation |
126 TN9/W64 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior stiffness and enables it to support substantial radial dynamic load ratings of 556 lbf and static load ratings of 108 lbf, effectively managing complex combined loads.
- High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces, contributing to a high limiting speed of 45,000 rpm, making it a capable high-speed bearing.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, and featuring tight dimensional tolerances, this bearing ensures precise running accuracy and long-term durability.
- Ready-to-Install Convenience: The bearing is pre-lubricated (W64), facilitating immediate installation and initial operation without additional lubrication steps.
126 TN9/W64 Bearing Typical Application Areas
This versatile double row angular contact ball bearing is ideally suited for:
- Small electric motors and high-speed spindles
- Precision instruments and medical devices
- Office automation equipment (e.g., printers, scanners)
- Robotic drives and small gearboxes
