NJ 2224 ECM

The NJ 2224 ECM stands out as a robust single row cylindrical roller bearing, specifically engineered for heavy-duty industrial applications that demand high radial load capacity. Featuring a 120mm bore, 215mm outside diameter, and 58mm width, this NJ-design bearing is equipped with two integral flanges on the outer ring and one on the inner ring. This specific configuration allows it to accommodate axial displacement in one direction, providing essential stability for rotating shafts. The "ECM" suffix signifies an optimized internal design paired with a machined brass cage, which is roller-centered to minimize friction and heat generation, ensuring the unit maintains peak performance even during high-speed operations reaching up to 3,600 r/min.

Beyond its impressive load ratings-with a basic dynamic load capacity of 520 kN-the NJ 2224 ECM is highly valued for its separable design. This feature simplifies mounting and dismounting, allowing for easier maintenance and the ability to interchange components if necessary. Built to the SKF Explorer performance class (or equivalent high-tier standards), this bearing is a reliable choice for demanding environments like gearboxes, large electric motors, and heavy machinery. Its precision-ground rollers and advanced metallurgy contribute to a longer service life and reduced vibration, making it a cost-effective solution for operators looking to minimize downtime and maximize energy efficiency in their mechanical systems.
