Product Overview: The NU 309 Cylindrical Roller Bearing
The NU 309 bearing is a high-performance component from our NU Series of Cylindrical Roller Bearings. Engineered for exceptional radial load capacity, this bearing features two integral flanges on the outer ring and a flangeless inner ring. This design allows for axial displacement between the shaft and the housing within the bearing itself, making it ideal for applications where thermal expansion or contraction of the shaft is anticipated and must be accommodated without stressing other machine parts. With precise dimensions of 45mm bore, 100mm outer diameter, and 25mm thickness, the NU 309 is built to deliver reliable operation and extended service life in demanding industrial environments.
As a trusted supplier of industrial bearings and mechanical parts, we ensure our NU 309 bearings meet stringent industry standards, providing robust and efficient solutions for a wide range of machinery. Its ability to handle high speeds and heavy radial loads makes it a cornerstone in many critical industrial applications.
