Product Overview: The NJ 204 Cylindrical Roller Bearing
The NJ 204 is a single-row cylindrical roller bearing engineered to handle high radial loads and accommodate axial displacement in one direction. With principal dimensions of 20mm bore diameter, 47mm outer diameter, and 14mm thickness, this bearing is a compact and robust solution for various industrial applications. As part of the NJ 200 Series, it features two integral flanges on the outer ring and one on the inner ring, allowing it to provide axial location for a shaft in a single direction. This design makes it suitable for use as a locating bearing.
Our NJ 204 bearings are manufactured to the highest industry standards, ensuring reliable performance and a long service life. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies both installation and maintenance procedures.
