Product Overview: The NU 209 Cylindrical Roller Bearing
The NU 209 bearing is a high-performance single-row Cylindrical Roller Bearing, part of our robust NU 200 Series. Specifically designed with dimensions of 45mm bore diameter, 85mm outer diameter, and 23mm thickness, this bearing is characterized by its integral flanges on the outer ring and a plain, separable inner ring. This design allows for axial displacement of the shaft relative to the housing, making it ideal for applications where thermal expansion or contraction might occur, and where high radial load capacity is paramount.
As a crucial component in heavy-duty machinery, the NU 209 bearing offers exceptional rigidity, precision, and the ability to operate at high speeds. Its separable components simplify mounting and dismounting, contributing to easier maintenance and assembly processes. We supply these high-quality industrial bearings engineered to meet stringent industry standards, ensuring reliable and long-lasting performance in the most demanding environments.
