Product Overview: The NU 217 Cylindrical Roller Bearing
The NU 217 bearing is a precision-engineered component from our comprehensive NU 200 Series of Cylindrical Roller Bearings, featuring dimensions of 85mm bore diameter, 150mm outer diameter, and 28mm thickness. This single-row cylindrical roller bearing is specifically designed with no flanges on the outer ring, which allows for axial displacement of the shaft relative to the housing. This design is crucial for applications where thermal expansion or contraction might occur, preventing unwanted axial loads and ensuring smooth, unhindered operation.
Known for their high radial load capacity and suitability for high-speed applications, NU type cylindrical roller bearings are indispensable in heavy-duty industrial machinery. Our NU 217 bearings are manufactured to rigorous industry standards, providing exceptional durability and reliable performance in demanding environments. They offer excellent stiffness and are ideal for situations requiring precise radial guidance and the accommodation of axial movement. Explore our full range of cylindrical roller bearings to find the optimal solution for your industrial needs.
