Product Overview: The NU 2308 Cylindrical Roller Bearing
The NU 2308 bearing is a high-performance component within our NU 2300 Series of Cylindrical Roller Bearings. This specific bearing features a bore diameter of 40 mm, an outer diameter of 90 mm, and a thickness of 33 mm. The 'NU' designation indicates that the bearing has two integral flanges on the outer ring and a smooth, separable inner ring. This design allows for axial displacement between the shaft and the housing within the bearing itself, making it highly versatile for applications where thermal expansion or contraction might occur, or where precise axial positioning is not critical.
As a leading supplier of industrial bearings and mechanical parts, we offer NU 2308 bearings engineered to meet demanding industrial requirements. These bearings are particularly suited for applications involving heavy radial loads and high-speed operation, delivering exceptional reliability and extended service life. Their robust construction and precision manufacturing ensure smooth and efficient mechanical performance across a wide range of industrial machinery.
