The 6706-ZZ is a specialized, ultra-thin single-row deep groove ball bearing engineered for high-performance applications where every millimeter of space is vital. Featuring dual non-contact metal shields (ZZ), this bearing provides a reliable defense against larger particles and debris while maintaining factory-grade lubrication for extended service intervals. With a 30mm bore, 37mm outer diameter, and a remarkably slim 4mm width, it is the premier selection for lightweight drone motors, optical sensors, and micro-automation systems requiring low-torque rotation and high-speed stability.
