Ultra-Thin Design & High-Speed Performance
Precision-engineered thin-wall miniature bearings (691-699Z series) reduce weight and space requirements while maintaining exceptional rotational accuracy. Ideal for compact applications like drones, RC models, and small machinery.
Premium Material & Durability
Hardened chrome steel construction with deep groove raceways ensures extended lifespan under high-speed loads. Corrosion-resistant shields (Z-type) protect against dust and debris.
Precision Engineering for Demanding Use
Tight tolerances (±0.001mm) and polished surfaces minimize friction, delivering silent operation at 20,000+ RPM. Perfect for medical devices, robotics, and high-end instrumentation.
Bulk Pricing Advantage
Direct factory sourcing guarantees the lowest global wholesale rates. Custom bulk packaging available for industrial buyers.
Versatile Cross-Industry Application
Optimized for aerospace prototypes, automotive sensors, and miniature gearboxes. Compatible with 1-3mm shaft diameters (check model specs).
Ready-to-Ship Global Stock
ISO-certified with 72-hour dispatch from multiple warehouses. MOQ flexible for resellers and OEMs. *Note: Specify "Z" suffix for shielded variants in order.*
