Product Overview: The NN 3064 Double-Row Cylindrical Roller Bearing
The NN 3064 is a high-precision, double-row cylindrical roller bearing engineered for applications demanding exceptional rigidity and high radial load-carrying capacity. With principal dimensions of 320x480x121mm, this bearing is a key component in heavy industrial machinery. As part of our NN 3000 Series, it belongs to a family of non-locating bearings designed to accommodate axial displacement of the shaft relative to the housing. The NN design features two rows of rollers and is typically used where the shaft must be located axially by other means.
Manufactured to exacting standards, the NN 3064 bearing provides superior performance in high-speed, high-load environments. Its design ensures low friction and long service life, making it a reliable choice for machine tool spindles, rolling mills, and large gearboxes.
