Product Overview: The NJ 2312 Cylindrical Roller Bearing
The NJ 2312 is a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial applications. As a key component in our NJ Series and the broader NJ 2300 Series, this bearing features dimensions of 60x130x46mm. The 'NJ' designation indicates a specific flange configuration with two integral flanges on the inner ring and one on the outer ring. This design allows the bearing to accommodate high radial loads and also locate the shaft axially in a single direction, making it ideal for applications requiring precise shaft guidance. The separable nature of the outer ring simplifies the mounting and dismounting process, providing greater flexibility during assembly and maintenance. Manufactured from premium-grade steel, the NJ 2312 ensures exceptional durability and a long service life under heavy loads and high speeds.
