Engineered for mechanical setups requiring dependable radial support within tightly confined axial envelopes, the 16002-ZZ is a high-grade narrow-profile deep groove ball bearing. Fitted with two low-drag pressed-steel shields (ZZ), it blocks harmful dust and particulate matter while ensuring the factory-installed lubricating grease remains sealed within the rolling elements. Because these metal shields operate without touching the inner ring, the 16002-ZZ exhibits minimal starting torque and negligible friction-induced heat. It stands as the ideal selection for 15mm shaft assemblies, such as medical diagnostic equipment, lightweight power tools, and automated testing devices.
