Key Performance Advantages:
Precision C2 Clearance: The C2 internal clearance is tighter than standard, reducing radial play for applications requiring high running accuracy and minimal vibration.
High-Speed Performance: Metal shields (ZZ) are non-contact, meaning they do not generate friction, allowing the bearing to reach significantly higher RPMs compared to sealed versions.
Space-Saving Design: Part of the 619 (6900) series, this bearing offers a low profile, making it perfect for compact robotic arms, dental equipment, and precision instruments.
