Product Overview: The NJ 2218 Cylindrical Roller Bearing
The NJ 2218 bearing is a high-performance single row cylindrical roller bearing, essential for applications demanding high radial load capacity and precision. Part of our comprehensive NJ 2200 Series within the larger NJ Series of Cylindrical Roller Bearings, this bearing features a bore diameter of 90mm, an outer diameter of 165mm, and a thickness of 41mm. Its design includes two integral flanges on the outer ring and one integral flange on the inner ring, allowing it to accommodate axial displacement in one direction only. This makes the NJ 2218 ideal for critical industrial machinery where precise shaft location and significant radial loads are present.
As a leading supplier of industrial bearings and mechanical parts, we ensure our NJ 2218 bearings are manufactured to the highest industry standards. These bearings provide excellent stiffness, low friction, and reliable operation, contributing to the longevity and efficiency of your equipment. They are particularly well-suited for heavy-duty applications, offering robust performance and simplified mounting due to their separable components.
