NU 330 ECM

The NU 330 ECM is a high-performance single row cylindrical roller bearing engineered to handle heavy radial loads and high-speed operations. Featuring a robust machined brass cage (M) that is surface-centered, this bearing offers superior stability and reduced friction even under demanding thermal conditions. The "NU" design incorporates two integral flanges on the outer ring and a smooth, flangeless inner ring, allowing for non-locating axial displacement within the bearing itself. This makes it an ideal solution for accommodating shaft expansion or contraction caused by temperature fluctuations in heavy-duty machinery.

Built to exacting precision standards, the NU 330 ECM excels in applications ranging from industrial gearboxes and electric motors to large-scale pumps. The optimized internal geometry (E) enhances the load-carrying capacity and promotes the formation of a consistent lubricant film, significantly extending the service life of the component. With its high-grade steel construction and refined raceway finishes, this bearing minimizes noise and vibration, ensuring operational reliability in the most rigorous industrial environments.
