The MR83-ZZ is an ultra-compact, single-row deep groove ball bearing equipped with dual-sided metal shields. Engineered for environments that demand extreme precision within heavily restricted spaces, this miniature bearing delivers reliable protection against microscopic debris while ensuring near-zero rotational friction. Featuring a 3 mm bore, an 8 mm outer diameter, and a 3 mm width, the MR83-ZZ is a critical component for micro-motors, precision instruments, and advanced robotics where smooth, high-velocity operation is required.
