NJ 318 ECM

The NJ 318 ECM is a high-performance single row cylindrical roller bearing engineered to handle heavy radial loads at high speeds. This specific design features two integral flanges on the outer ring and one on the inner ring, allowing it to accommodate axial displacement in one direction. The "ECM" suffix denotes an optimized internal design paired with a machined brass cage, which is glass-fiber reinforced and roller-centered. This construction ensures superior stability, reduced friction, and excellent lubricant distribution, making it an ideal choice for demanding industrial gearboxes and electric motors.

Built for durability and precision, the NJ 318 ECM offers a 90mm bore diameter and a 190mm outside diameter, conforming to standard metric dimensions for easy integration into existing systems. The optimized surface finish on the raceways promotes the formation of a stable hydrodynamic oil film, significantly extending service life even in harsh operating environments. Whether you are dealing with high-frequency vibrations or extreme radial forces, this bearing provides the structural integrity and rotational accuracy required to minimize downtime and maintain peak mechanical efficiency.
