Product Overview: The NU 2217 Cylindrical Roller Bearing
The NU 2217 bearing is a precision-engineered component belonging to our comprehensive NU 2200 Series Cylindrical Roller Bearings. With key dimensions of 85mm bore diameter, 150mm outer diameter, and 36mm thickness, this bearing is designed for superior performance in demanding industrial environments. The "NU" designation signifies that the bearing features two integral flanges on its outer ring and a smooth inner ring, which allows for axial displacement between the shaft and the housing. This characteristic makes the NU 2217 ideal for applications where the shaft expands or contracts due to temperature variations, or where precise axial location is not required.
As a vital component in power transmission and heavy machinery, the NU 2217 cylindrical roller bearing excels in handling high radial loads and moderate speeds. Its robust construction ensures long service life and reliable operation, contributing to the efficiency and longevity of your equipment. Explore our full range of cylindrical roller bearings for various industrial needs, including the versatile NU 2216 and NU 2218, which share similar design principles.
