Product Overview: The NJ 332 Cylindrical Roller Bearing
The NJ 332 is a high-capacity single-row cylindrical roller bearing, engineered to perform under demanding industrial conditions. With principal dimensions of 160mm Bore Diameter, 340mm Outer Diameter, and 68mm Thickness, this bearing is a crucial component in heavy machinery. As part of our extensive NJ 300 Series, the NJ 332 features a specific design with two integral flanges on the inner ring and a single flange on the outer ring. This configuration allows it to accommodate not only heavy radial loads but also light axial loads in one direction, providing effective shaft location.
The separable nature of the NJ 332, where the outer ring can be mounted independently from the inner ring and roller assembly, simplifies both installation and maintenance procedures. Manufactured from high-purity, hardened bearing steel, this component ensures durability and a long operational life.
