626-2Z/WT Bearing Product Overview & Core Advantages
The 626-2Z/WT is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and operational stability. Featuring shielded construction (2Z), this bearing offers effective contamination protection while maintaining low friction characteristics. Manufactured to ABEC 1 | ISO P0 tolerance standards with optimized radial internal clearance (CN), it delivers consistent precision and smooth operation across diverse industrial environments. The compact design with 6mm bore diameter makes it ideal for space-constrained applications demanding high rotational accuracy and extended service life.

626-2Z/WT Bearing Structural Features & Performance Benefits
Optimized Single Row Design: The deep groove raceway geometry enables excellent radial load capacity while accommodating moderate axial loads in both directions. The precision-ground chrome steel components ensure dimensional stability and wear resistance.
Shielded Protection System: The double-sided steel shields (2Z) provide effective sealing against dust and particulate contaminants while generating minimal friction compared to contact seals. This configuration supports the limiting speed of 32,000 rpm while maintaining protection.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with CN clearance, the bearing delivers consistent running accuracy and vibration characteristics. The all-chrome steel construction (rings, balls, and cage) ensures material homogeneity and thermal stability across the operating temperature range of -30°C to 120°C.
Weight-Optimized Design: At only 8.12 grams, the bearing offers an excellent strength-to-weight ratio, making it suitable for applications where rotational mass reduction is critical.
