Optimized for high-density mechanical designs where every millimeter counts, the MR72-ZZ is an ultra-small, single-row deep groove ball bearing. Featuring a 2mm bore and a compact 7mm outer diameter, this component is designed to facilitate smooth rotational motion within extremely confined footprints. Equipped with two non-contact pressed steel shields (ZZ), the MR72-ZZ maintains factory-grade lubrication while shielding the internal raceways from airborne contaminants. It provides a robust, low-maintenance rotary solution for engineers developing cutting-edge medical devices, micro-robotics, and high-performance portable electronics.
