Product Overview: The NU 2213 Cylindrical Roller Bearing
The NU 2213 bearing is a robust and highly efficient component within our comprehensive NU 2200 Series of Cylindrical Roller Bearings. This specific bearing, with its precise dimensions of 65mm bore, 120mm outer diameter, and 43mm thickness, is engineered to handle substantial radial loads with high rigidity and accuracy. Its distinguishing feature, the 'NU' designation, indicates that it has two integral flanges on the outer ring and a smooth inner ring, making the inner ring axially displaceable relative to the outer ring. This design is crucial in applications where axial displacement of the shaft relative to the housing is expected, as it allows for thermal expansion without imposing undue stress on the bearing or adjacent components.
As a trusted supplier of industrial bearings and mechanical parts, we ensure that our NU 2213 cylindrical roller bearings are manufactured to rigorous industry standards. Their design facilitates ease of mounting and dismounting, as the outer ring and roller assembly can be separated from the inner ring. This separability simplifies maintenance and replacement procedures, reducing downtime and operational costs. The NU 2213 is an ideal choice for machinery demanding high load capacity, high speed capabilities, and excellent operational stability.
