626-2Z/VT901 Bearing Product Overview & Core Advantages
The 626-2Z/VT901 is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and smooth operation. Featuring shielded construction (2Z) and manufactured to ABEC 1 | ISO P0 tolerance standards, this precision bearing delivers consistent performance with minimal maintenance. Its compact design with 6mm bore diameter and 19mm outside diameter makes it ideal for space-constrained assemblies while maintaining robust load handling capabilities.
626-2Z/VT901 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Effective contamination protection while maintaining high-speed capability |
| VT901 | No lubrication (dry) | Suitable for applications where lubricant migration is unacceptable |
626-2Z/VT901 Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The deep groove raceway geometry enables excellent radial load capacity (447 lbf dynamic, 161 lbf static) while accommodating moderate axial loads in both directions.
High-Speed Performance: With a limiting speed of 32,000 rpm, the bearing maintains stable operation at high rotational speeds thanks to precision-ground chrome steel components and optimized internal clearance (CN).
Contamination Protection: The shielded design provides effective protection against dust and particulate contamination while minimizing friction losses compared to contact seals.
Material Excellence: Manufactured from high-grade chrome steel for rings, balls, and cage, ensuring dimensional stability and long service life across the operating temperature range (-30°C to 120°C).
626-2Z/VT901 Bearing Typical Application Areas
- Small Electric Motors: Ideal for miniature DC motors, stepper motors, and fan motors requiring reliable high-speed operation
- Precision Instruments: Suitable for medical devices, optical equipment, and measuring instruments where compact bearing dimensions and accuracy are critical
- Office Automation Equipment: Commonly used in printers, scanners, and copiers for shaft support in paper handling mechanisms
- Robotics & Automation: Applied in small robotic joints, linear actuators, and positioning systems requiring precision bearings with consistent performance
