NU 2320 ECJ

The NU 2320 ECJ is a high-performance single row cylindrical roller bearing engineered to handle substantial radial loads in demanding industrial environments. With a precise 100mm bore, 215mm outside diameter, and a robust 73mm width, this bearing features a specialized NU design with two integral flanges on the outer ring and a flangeless inner ring. This configuration is particularly effective for managing axial displacement within the housing, making it a reliable choice for electric motors, gearboxes, and heavy-duty pumps where shaft expansion is a factor.

What sets the NU 2320 ECJ apart is its optimized internal geometry combined with a high-strength stamped steel cage (indicated by the J suffix). The "EC" designation signifies an enhanced internal design that increases the roller count and size, significantly boosting its dynamic load rating to approximately 670 kN. Because the inner ring is completely separable, maintenance and installation are far more straightforward compared to non-separable units. This bearing not only minimizes friction to support higher operating speeds but also ensures a longer service life under tough conditions like those found in traction motors and large-scale manufacturing machinery.
