Precision Miniature Deep Groove Ball Bearings for High-Speed Applications

Ultra-smooth 11x5x12.5mm stainless steel construction with hardened chrome steel balls ensures exceptional durability and low friction rotation. Advanced cage design minimizes vibration for whisper-quiet operation in high-RPM scenarios.

Factory-lubricated with high-temperature grease for maintenance-free performance in printers, drones, RC cars, and medical equipment. Tighter-than-industry-standard tolerances (±0.001mm) guarantee consistent performance under radial/axial loads.

Ideal for replacing OEM components in miniature motors, optical devices, and precision instruments. Electro-polished raceways prevent particulate contamination in cleanroom environments. Bulk packaging available for industrial buyers.

100% tested for rotational accuracy (ABEC-1 standards) with corrosion-resistant shields protecting internal components. Direct manufacturer pricing allows 40-60% savings versus retail channels.
