Description
The NU 310 ECJ is a high-performance single row cylindrical roller bearing designed for applications demanding high radial load capacity and efficient high-speed operation. Its NU design, featuring two integral flanges on the outer ring and none on the inner ring, permits axial displacement of the shaft in both directions, making it well-suited for conditions involving thermal expansion or shaft movement.
The separable design facilitates easy installation, removal, and interchangeability of components, reducing downtime and simplifying maintenance. Equipped with a durable sheet metal cage, the bearing ensures stability, low friction, and consistent long service life. As part of the SKF Explorer performance class, the NU 310 ECJ delivers optimized load distribution, improved reliability, and dependable efficiency in motors, pumps, gearboxes, compressors, and heavy-duty industrial machinery.
