High-Performance Design for Precision Micro-Mechanics
These flanged miniature ball bearings are engineered to deliver superior rigidity, running accuracy, and long-term reliability under dynamic operating conditions. They provide stable rotational performance across varying loads and speeds—making them an essential component for advanced micro-systems, from optical positioning stages to miniature robotic joints.
✅ Flanged Structure for Enhanced Mounting Precision
The integrated flange offers secure positioning and effectively resists axial displacement, improving system stability and alignment. This is especially important for compact linear modules, micro-rotary platforms, and fine-adjustment mechanisms where even minimal play can affect overall accuracy.
✅ Engineered for Low-Vibration High-Speed Use
Precision-ground raceways and optimized internal geometry reduce rotational resistance and minimize vibration at elevated speeds. This enables smooth, quiet operation in demanding applications such as drone camera gimbals, high-speed spindle drives, and miniature scanning systems.
✅ Robust Material with Corrosion Resistance
Made from hardened chrome steel with special surface treatment to enhance wear resistance and protect against light corrosion. This ensures reliable performance in environments exposed to humidity, occasional splashes, or cleaning agents—suitable for laboratory devices, food-grade equipment, and indoor industrial units.
✅ Sealed and Pre-Lubricated for Maintenance-Free Operation
Factory-filled with a high-stability grease and sealed on both sides to retain lubrication and exclude contaminants. This design eliminates the need for re-greasing, making the bearings ideal for sealed assemblies such as small DC motors, encoder systems, and medical micro-drives.
Perfect for integration into precision automation equipment, desktop CNC systems, and high-end optical devices, these bearings contribute to smooth, reliable, and repeatable motion in compact designs. They are the go-to choice for engineers who require consistent performance, easy installation, and long service life in space-constrained, high-precision applications.
