Product Overview: The NJ 408 Cylindrical Roller Bearing
The NJ 408 is a high-capacity single-row cylindrical roller bearing, engineered to handle substantial radial loads while accommodating axial displacement in one direction. With precise dimensions of 40x110x27mm, this bearing is a key component in our Cylindrical Roller Bearings collection and specifically part of the NJ 400 Series. Its design features two integral flanges on the inner ring and a single flange on the outer ring, allowing it to locate the shaft axially in a single direction. This configuration makes it ideal for applications requiring both heavy radial support and axial shaft guidance.
As a premier supplier of industrial components, we ensure our NJ 408 bearings meet rigorous industry standards for performance and durability. The separable design simplifies mounting and dismounting, as the inner and outer rings can be installed independently. This bearing is a reliable solution for a wide range of demanding industrial machinery.
