Product Overview: The NN 3056 Double-Row Cylindrical Roller Bearing
The NN 3056 is a high-precision double-row cylindrical roller bearing, engineered to handle extremely high radial loads and operate at high speeds. With its principal dimensions of 280x420x106mm, this bearing is a vital component within our NN 3000 Series. As part of the wider Cylindrical Roller Bearings category, the NN 3056 features two rows of cylindrical rollers, providing exceptional rigidity and stability, making it the preferred choice for applications demanding superior rotational accuracy, such as machine tool spindles.
As a leading supplier of industrial components, we ensure our NN 3056 bearings meet stringent industry standards. The inner ring is separable, which simplifies the mounting and dismounting process. This design allows the bearing to accommodate thermal expansion of the shaft, ensuring consistent performance in demanding operational environments.
