Description
The NU 317 ECP is a high-performance single row cylindrical roller bearing designed to withstand heavy radial loads while maintaining reliable operation at high speeds. Its NU design, with two integral flanges on the outer ring and none on the inner ring, enables axial displacement of the shaft in both directions, making it particularly effective in applications where thermal expansion or shaft movement must be managed.
The separable construction simplifies installation, dismounting, and interchangeability of components, helping to reduce downtime and streamline maintenance. Featuring a reinforced non-metallic cage, the bearing ensures stability, low friction, and extended service life even under demanding operating conditions. As part of the SKF Explorer performance class, the NU 317 ECP offers superior reliability, optimized efficiency, and consistent durability in motors, gearboxes, pumps, compressors, and other heavy-duty machinery.
