Single Row Cylindrical Roller Bearing – NU 326 ECJ/C3
The NU 326 ECJ/C3 is a single row cylindrical roller bearing in the NU design, capable of carrying very high radial loads at high speeds. With two integral flanges on the outer ring and none on the inner ring, it accommodates axial displacement in both directions. Its separable design simplifies mounting and interchangeability of components, while the C3 clearance ensures optimized performance under demanding conditions.

Description
The NU 326 ECJ/C3 cylindrical roller bearing is engineered for heavy-duty applications where both high radial load capacity and high-speed capability are critical. Its NU configuration—with two flanges on the outer ring and no flanges on the inner ring—enables axial displacement of the shaft in both directions, making it suitable for systems where thermal expansion or contraction occurs.
A key advantage of this bearing is its separable design, which allows the rings and roller-cage assembly to be mounted independently. This simplifies installation, inspection, and maintenance, while also allowing component interchangeability to minimize downtime.
The NU 326 ECJ/C3 is manufactured to SKF Explorer performance standards, ensuring low friction, extended service life, and reliability even under challenging conditions. With its robust sheet metal cage and C3 radial internal clearance, it is ideal for applications requiring durability, efficiency, and consistent performance.
