NJ 324 ECM

The NJ 324 ECM is a high-capacity, single-row cylindrical roller bearing engineered to handle heavy radial loads in demanding industrial environments. With a bore diameter of 120mm, an outside diameter of 260mm, and a width of 55mm, this bearing features the "NJ" configuration, which includes two integral flanges on the inner ring and one on the outer ring. This specific design allows the bearing to provide axial displacement in one direction, making it an essential component for shafts that experience thermal expansion. The "ECM" suffix denotes an optimized internal geometry for increased load ratings and a robust, roller-centered machined brass cage, which ensures exceptional stability and performance during high-speed operations.

Beyond its structural specifications, the NJ 324 ECM is built for longevity and reduced maintenance in applications like large electric motors, heavy-duty gearboxes, and industrial pumps. The precision-ground rollers and advanced surface finishes significantly lower friction, which in turn minimizes heat generation and energy consumption. By maintaining tight tolerances even under significant thermal stress, this bearing helps eliminate excessive vibration, protecting the surrounding machinery and extending the overall service life of the equipment. Its combination of high-grade steel and a reinforced brass cage makes it a reliable choice for engineers who prioritize machine uptime and operational efficiency.
