Product Overview: The NJ 2209 Cylindrical Roller Bearing
The NJ 2209 is a high-capacity single-row cylindrical roller bearing with principal dimensions of 45x85x23mm. As a key component in our Cylindrical Roller Bearings category, it belongs to the versatile NJ 2200 Series. Its distinctive NJ design features two integral flanges on the inner ring and a single flange on the outer ring. This configuration allows the bearing to accommodate not only heavy radial loads but also light axial loads in one direction, making it excellent for locating a shaft axially. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation and maintenance procedures.
Manufactured to exacting standards from premium-grade bearing steel, the NJ 2209 is engineered for reliability and long service life in demanding industrial environments. Its low-friction characteristics make it suitable for applications requiring high rotational speeds. As a trusted supplier, we provide components that deliver consistent performance and durability for a wide range of machinery.
