Product Overview: The NU 313 Cylindrical Roller Bearing
The NU 313 bearing is a high-performance component within our NU Series of Cylindrical Roller Bearings, specifically part of the NU 300 Series. Designed to handle significant radial loads and accommodate high rotational speeds, this bearing is characterized by its separable design, where the inner ring, outer ring, and roller assembly can be mounted independently. The NU type features two integral flanges on the outer ring and no flanges on the inner ring, allowing for axial displacement of the shaft relative to the housing. This design is particularly beneficial in applications where thermal expansion or contraction of the shaft must be compensated without inducing axial stress on the bearing.
Our NU 313 bearings, with precise dimensions of 65mm bore diameter, 140mm outer diameter, and 33mm thickness, are manufactured to exacting industry standards. They are a cornerstone for robust industrial machinery, providing reliable and efficient operation in demanding environments. As a trusted supplier of industrial bearings and mechanical parts, we ensure our products meet the highest quality benchmarks, offering longevity and optimal performance. Explore our full range of cylindrical roller bearings to find the ideal solution for your specific industrial requirements.
