Product Overview: NJ 330 Cylindrical Roller Bearing
The NJ 330 is a high-performance, single-row cylindrical roller bearing engineered to handle heavy radial loads and high speeds. With dimensions of 150x320x65mm, this bearing is a crucial component in demanding industrial machinery. As part of the NJ Series, its design features two integral flanges on the inner ring and one on the outer ring. This configuration allows the bearing to provide axial location for the shaft in a single direction, making it ideal for applications requiring precise shaft guidance under heavy load.
Our NJ 330 bearings are manufactured to the highest industry standards, ensuring reliability and a long service life. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies installation and maintenance procedures.
