High-Performance Design for Precision Micro-Mechanics
The flanged miniature ball bearing is precision-engineered to deliver outstanding rigidity, rotational accuracy, and long-term reliability in ultra-compact mechanical systems. Despite its miniature size, this bearing ensures stable performance under light to moderate loads and variable speeds—making it a critical component in high-precision micro-applications such as micro-motors, optical encoders, and miniaturized robotic mechanisms.
✅ Flanged Structure for Enhanced Mounting Precision
The integrated flange on the outer ring provides reliable axial positioning and prevents lateral shifting during operation. This feature ensures consistent alignment and reduces play in tight-tolerance assemblies, making the bearings ideal for compact linear stages, micro-rotary tables, and fine-adjustment optics where even micron-level deviations can compromise system accuracy.
✅ Engineered for Low-Vibration High-Speed Use
Featuring precision-ground raceways and optimized internal geometry, the bearings delivers minimal friction and smooth rotational dynamics. Its design significantly reduces vibration and noise at elevated speeds, enabling silent, efficient operation in demanding applications such as miniature drone motors, small sensor modules, high-speed micro-spindles, and portable scanning devices.
✅ Robust Material with Corrosion Resistanece
Crafted from high-grade hardened chrome steel and enhanced with a protective zinc coating, this bearing offers excellent wear resistance and improved protection against humidity, occasional moisture, and mild environmental exposure. Suitable for use in laboratory instruments, indoor industrial equipment, and consumer electronics where durability and cleanliness are essential.
✅ Sealed and Pre-Lubricated for Maintenance-Free Operation
Double-shielded with rigid metal seals (ZZ type) and factory-lubricated with high-stability grease, the bearings retains lubrication effectively while blocking dust, particles, and other contaminants. This sealed-for-life design eliminates the need for re-lubrication, making it perfect for enclosed systems such as micro DC motors, miniature gear trains, medical diagnostic devices, and battery-powered precision tools.
With ultra-miniature bearings dimensions is engineered for seamless integration into space-critical designs. It is the preferred solution for engineers developing advanced micro-mechatronic systems, wearable technology, handheld optical devices, and desktop automation platforms—where precision, reliability, and compactness are non-negotiable.
Choose the bearings for flawless motion control in the smallest spaces—delivering consistent performance, easy installation, and extended service life in the most demanding miniature applications.
