The 683-2Z RICH is a miniature deep groove ball bearing engineered for ultra-compact precision mechanisms. Designed by RICH and produced in China, it measures just 3 mm in bore, 7 mm in outer diameter, and 3 mm in width, with a feather-light weight of 0.001 kg.
This bearing is fitted with metal shields on both sides (2Z) that help retain lubrication and block out contaminants such as dust and debris. Its internal construction features a solid steel cage for stable rotation and typically includes standard radial clearance (CN) to promote smooth performance in high-precision, low-load applications. Its tiny footprint and efficient load-handling characteristics make it ideal for use in micro-electromechanical systems (MEMS), hobby devices, compact motors, and miniature robotics.
