Product Overview: The NJ 215 Cylindrical Roller Bearing
The NJ 215 bearing is a single-row cylindrical roller bearing designed for high performance in demanding industrial applications. With principal dimensions of 75mm Bore Diameter, 130mm Outer Diameter, and 25mm Thickness, it is engineered to handle substantial radial loads at high speeds. As part of the versatile NJ 200 Series, this bearing features two integral flanges on the outer ring and a single flange on the inner ring. This specific configuration allows the bearing to locate a shaft axially in one direction, making it an excellent choice for applications requiring precise shaft guidance. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies installation and maintenance procedures. Our NJ 215 bearings are manufactured to the highest industry standards, ensuring reliability and longevity.
