Product Overview: The NN 3015 Double Row Cylindrical Roller Bearing
The NN 3015 bearing is a high-precision, double-row cylindrical roller bearing, renowned for its exceptional radial load capacity and high rigidity. With a bore diameter of 75 mm, an outer diameter of 115 mm, and a thickness of 34 mm, this bearing is engineered to provide superior performance in applications requiring robust support and precise rotational accuracy.
Part of our specialized NN 3000 Series NN Series, the NN 3015 features two rows of rollers, significantly enhancing its ability to handle heavy radial loads and maintain shaft stability. Its design allows for the accommodation of axial displacement between the shaft and the housing, making it ideal for non-locating bearing positions. As a trusted supplier of industrial bearings, we ensure our NN 3015 bearings meet stringent industry standards for durability and reliability, offering prolonged service life and consistent operation in demanding industrial environments.
