The MR82-ZZ is an ultra-small, precision-engineered radial ball bearing designed for micro-mechanical assemblies where space is limited and high-speed efficiency is critical. Featuring a 2 mm bore, this miniature bearing is equipped with dual metal shields (ZZ) to provide a reliable barrier against dust while maintaining a low-friction environment. Manufactured from high-carbon chrome steel, the MR82-ZZ is the go-to component for developers of RC models, high-end optical instruments, and micro-motors requiring smooth, quiet rotation.

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.
