Product Overview: The NU 2208 Cylindrical Roller Bearing
The NU 2208 bearing is a high-performance component within our extensive NU 2200 Series and broader NU Series of Cylindrical Roller Bearings. Featuring precise dimensions of 40mm bore diameter, 80mm outer diameter, and 23mm thickness, this bearing is specifically engineered to accommodate significant radial loads and operate efficiently at high rotational speeds. Its distinctive 'NU' configuration features two integral flanges on the outer ring and a smooth, flangeless inner ring. This design allows for axial displacement of the shaft relative to the housing, which is crucial for managing thermal expansion and simplifying assembly processes, ensuring optimal performance and longevity in demanding industrial applications.
As a trusted supplier of industrial bearings, we ensure that our NU 2208 cylindrical roller bearings meet industry-standard specifications, providing reliable and consistent operation. Their robust construction and optimized design make them an essential component for machinery requiring durable and efficient rotational support, even under challenging operating conditions.
