Description
The NU 317 ECJ is a high-capacity single row cylindrical roller bearing designed to deliver reliable performance in applications requiring high radial load support and efficient high-speed operation. Featuring two integral flanges on the outer ring and none on the inner ring, the NU design accommodates axial displacement of the shaft in both directions, making it ideal for systems exposed to thermal expansion or misalignment.
Its separable construction simplifies installation, dismounting, and interchangeability of components, reducing downtime and maintenance costs. The sheet metal cage ensures strength, durability, and excellent stability under heavy loads, while maintaining low-friction operation.
As part of the SKF Explorer performance class, the NU 317 ECJ benefits from optimized internal geometry, providing improved load distribution, higher reliability, extended service life, and enhanced efficiency. This makes it particularly suitable for demanding applications such as gearboxes, compressors, pumps, electric motors, and heavy industrial machinery where consistent performance is essential.
