NU 322 ECM/C3

The NU 322 ECM/C3 is a high-performance single-row cylindrical roller bearing engineered for demanding industrial applications. As an NU-design bearing, it features two integral flanges on the outer ring and a flangeless inner ring, making the assembly separable for easier mounting and maintenance. This configuration is essential for accommodating axial displacement of the shaft relative to the housing, acting as an effective "floating" bearing. With a generous internal clearance designated as C3 (greater than normal), this bearing is well-suited for applications involving temperature variations or where slight misalignment may occur. Its robust construction and high-quality materials, including a durable machined brass cage (M), ensure stability and a long service life under heavy radial loads.

This specific bearing is optimized for both high radial load capacity and high-speed operation, making it a reliable choice for critical machinery across various sectors, including gearboxes, pumps, compressors, and rolling mills. The internal dimensions are a bore diameter (d) of 110 mm, an outside diameter (D) of 240 mm, and a width (B) of 50 mm. The "EC" suffix indicates an optimized internal geometry with a modified roller/end flange contact, further enhancing its load-carrying capability and extending operational life. By offering low friction and high rigidity, the NU 322 ECM/C3 provides smooth, efficient rotation, minimizing noise and vibration even in dynamic environments. Always refer to the manufacturer's technical data sheet for specific dynamic and static load ratings for your design requirements.
