Premium 618/1 Deep Groove Ball Bearing for Precision Instruments

Ultra-precision 1x3x1mm miniature bearing engineered for high-accuracy applications. Chrome steel construction with mirror-polished raceways ensures <0.001mm runout tolerance. Ideal for medical devices, optical encoders, and micro-motor assemblies.

Advanced cage-less design eliminates friction points, achieving 50,000 RPM at full load. Vacuum-grade lubrication prevents outgassing in sensitive environments.

Cost-optimized for bulk OEM procurement without sacrificing aerospace-grade quality. Compatible with Mitutoyo, Starrett, and Swiss measuring tools.

Direct-from-factory pricing with MOQ flexibility for industrial buyers. ISO 9001 certified production with 100% dimensional inspection.

Applications: Laboratory equipment, watch movements, drone gimbals, and dental handpieces. Stocked in bulk for immediate global shipping.

Note: 50% thinner than standard micro-bearings with identical load capacity.
