High-Precision Micro Miniature Ball Bearings – Industrial-Grade Performance
Premium chrome steel construction ensures superior durability and smooth rotation under high-speed conditions. Double-shielded (ZZ) and rubber-sealed (2RS) options provide optimal dust and moisture resistance for extended lifespan. Ultra-compact design (5mm to 9mm bore sizes) ideal for precision instruments, drones, RC models, medical devices, and small machinery. Mirror-polished raceways minimize friction for silent operation. Massive bulk order discounts available – wholesale pricing unmatched globally. Strict quality control guarantees ISO-certified bearings with consistent dimensional accuracy (ABEC-1 standard). Wide size range (625/635/686/696/606/626/636/687/697/607/627/637/688/698/608/628/638/689/609/629/639) covers diverse industrial and hobbyist needs. Ships worldwide with fast logistics.
