The NTN NU2212 C3 cylindrical roller bearing is a precision-engineered industrial roller bearing manufactured for heavy radial load applications and high-speed rotational performance. Designed with an NU-type configuration, the bearing features two integral flanges on the outer ring and no flanges on the inner ring, allowing axial displacement of the shaft relative to the housing. The C3 internal clearance provides additional radial clearance for applications involving thermal expansion, higher operating temperatures, or heavy operating loads. Manufactured using high-grade bearing steel and precision-ground raceways, the bearing delivers low friction, high rigidity, excellent durability, and long operational life. It is widely used in electric motors, gearboxes, pumps, compressors, conveyors, machine tools, industrial fans, and heavy industrial machinery.
