Product Overview: The NN 3009 Double-Row Cylindrical Roller Bearing
The NN 3009 is a high-precision, double-row cylindrical roller bearing with dimensions of 45x75x23mm. As a key component in our NN 3000 Series, this bearing is engineered to provide exceptional radial stiffness and accommodate very high radial loads. Its design, featuring two rows of cylindrical rollers, makes it ideal for applications that demand high rigidity and rotational accuracy, such as machine tool spindles. The inner ring is separable from the outer ring and roller assembly, which simplifies the mounting and dismounting process.
As a specialist supplier of industrial components, we offer the NN 3009 as a reliable solution for demanding machinery. This bearing is part of our extensive range of Cylindrical Roller Bearings, all manufactured to stringent industry standards to ensure consistent performance and a long service life. Its robust construction and precision engineering make it a superior choice for high-speed and heavy-load environments.
