The 6209-ZZ is a precision-engineered radial bearing featuring two non-contact metal shields to protect the internal rolling elements from larger debris while maintaining high-speed efficiency. With dimensions of 45 mm (bore), 85 mm (outer diameter), and 19 mm (width), this 62-series bearing is designed for applications where low friction torque is essential. Unlike rubber-sealed variants, the metallic shields (ZZ or 2Z) do not contact the inner ring, allowing the bearing to operate at significantly higher velocities with minimal heat generation.
