The 6801-ZZ is a high-performance, extra-thin section ball bearing designed for precision assemblies where minimizing friction and weight is paramount. Equipped with dual-sided metal shields (ZZ), this bearing excels in high-speed environments by retaining factory-grade lubricant while offering lower rotational torque compared to rubber-sealed alternatives. With a 12mm bore and a compact 21mm outer diameter, the 6801-ZZ is the ideal solution for high-frequency spindles, lightweight drone motors, and sensitive medical instrumentation requiring consistent, low-vibration rotation.
