Product Overview: The NU 2218 Cylindrical Roller Bearing
The NU 2218 bearing is a high-performance single row Cylindrical Roller Bearing, part of our robust NU 2200 Series. Specifically designed with a bore diameter of 90 mm, an outer diameter of 165 mm, and a thickness of 43 mm, this bearing is engineered to accommodate very heavy radial loads and high speeds. Its 'NU' designation signifies that it has two integral flanges on the outer ring and a smooth inner ring, allowing for axial displacement between the shaft and the housing within the bearing itself. This feature makes it ideal for applications where thermal expansion or contraction might occur, preventing unwanted axial stresses.
As a trusted supplier of industrial bearings and mechanical parts, we ensure our NU 2218 bearings meet stringent industry standards, offering exceptional durability and reliable performance in challenging operational environments. The precise manufacturing and robust design of the NU 2218 make it a cornerstone component in various heavy-duty machinery across diverse industries.
