Description
The NU 313 ECJ is a high-performance single row cylindrical roller bearing designed to support heavy radial loads and dependable high-speed operation. Its NU design, with two flanges on the outer ring and none on the inner ring, allows axial displacement in both directions, effectively accommodating thermal expansion and shaft movement.
With a separable construction, the bearing simplifies mounting, dismounting, and component replacement, improving maintenance efficiency. The robust sheet metal cage ensures stability under heavy loads, while the SKF Explorer performance class optimizes load distribution, reduces friction, and extends service life.
Engineered for reliability and durability, the NU 313 ECJ is widely used in gearboxes, compressors, electric motors, and heavy industrial machinery where consistent, low-maintenance performance is critical.
