Product Overview: The NJ 307 Cylindrical Roller Bearing
The NJ 307 is a high-performance single-row cylindrical roller bearing, meticulously engineered for applications demanding high radial load capacity and axial shaft location in one direction. With dimensions of 35x80x21mm, this bearing is a key component in our Cylindrical Roller Bearings range and a part of the versatile NJ 300 Series. Its design features two integral flanges on the inner ring and a single flange on the outer ring, allowing it to guide the shaft axially in a single direction while accommodating high radial forces. This makes it an excellent choice for a wide variety of industrial machinery where precision and reliability are paramount.
The separable nature of the NJ 307, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation and maintenance procedures. Manufactured from premium-grade bearing steel, it ensures durability and a long service life even in the most demanding operational environments.
