626-2Z/VT304 Bearing Product Overview & Core Advantages
The 626-2Z/VT304 is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and smooth operation. Featuring shielded construction (2Z), this bearing offers excellent contamination protection while maintaining low friction. Manufactured to ABEC 1 | ISO P0 tolerance standards with CN radial clearance, it delivers consistent precision and durability across a wide temperature range (-30° to 120°C). Its compact design (6×19×6 mm) makes it ideal for space-constrained applications demanding high rotational speeds up to 32,000 rpm.

626-2Z/VT304 Bearing Structural Features & Performance Benefits
Optimized Deep Groove Design: The single row construction with precision-machined raceways ensures excellent radial load capacity (447 lbf dynamic, 161 lbf static) while accommodating moderate axial loads in both directions.
Shielded Protection: Double-sided steel shields (2Z) provide effective sealing against dust and particulate contamination without significantly increasing friction, making them ideal for high-speed applications up to 32,000 rpm.
Premium Material Construction: Manufactured entirely from chrome steel (rings, balls, and cage), ensuring consistent hardness, wear resistance, and dimensional stability across the operating temperature range.
Precision Engineering: Built to ABEC 1 | ISO P0 tolerance class with CN radial internal clearance, delivering reliable performance in various industrial applications.
