NU 238 ECML/C3

The NU 238 ECML/C3 Single Row Cylindrical Roller Bearing is a high-performance solution engineered for applications requiring exceptional radial load capacity and the accommodation of axial shaft displacement. This specific bearing features an "NU" design, meaning it has two integral flanges on the outer ring and a smooth inner ring, allowing the shaft to move axially relative to the housing. With a substantial 190mm bore diameter, 340mm outer diameter, and a 55mm width, it is built to withstand heavy-duty industrial conditions.

The "E" suffix denotes an enhanced load-carrying capacity, achieved through optimized internal geometry or a larger number of rollers, while the "CM" or "CML" typically indicates a pressed steel cage, providing durability and reliable performance. The "C3" radial internal clearance is greater than standard, making it suitable for applications where thermal expansion might occur between the shaft and housing, or where heavy loads are present. This combination of features results in a bearing capable of high speeds, high rigidity, and prolonged service life. Commonly found in critical machinery such as industrial gearboxes, large electric motors, pumps, steel mills, paper machines, and other heavy industrial equipment, the NU 238 ECML/C3 ensures smooth operation and maximized uptime by effectively handling significant radial forces while allowing essential axial movement.
