626 ZZ Deep Groove Ball Bearing 6x19x6 mm | ISO 62 Series – Light | Double Shielded
Premium miniature precision bearing featuring the universal deep groove geometry. Engineered for high-speed performance up to 38,000 r/min (Oil). The 626-ZZ miniature ball bearing is capable of supporting significant radial loads and moderate axial loads, making it ideal for precision instrumentation, electric motors, and applications in less clean environments.

Ideally suited for a broad spectrum of precision and industrial equipment where environmental protection is valued:
Double non‑contact steel shields provide robust two‑side protection against dust and larger particulates in challenging environments. This configuration effectively seals in grease for extended service life while ensuring minimal rotational friction and low operating torque.
Built to the light series standard in a compact 6×19×6 mm envelope, this bearing offers increased radial load capacity. The universal deep‑groove design also reliably handles moderate axial loads from either direction, making it suitable for applications requiring both strength and compact dimensions.
Produced to consistent industrial tolerances with availability up to P5 precision grades. Its refined internal geometry minimizes friction and heat generation, supporting exceptional rotational accuracy, smoothness, and reliable performance even under high‑speed conditions.
