NN..Super Precision bearings
Double row cylindrical roller bearings of the NN 30 K and NNU 49 K series have two rows of rollers guided in a massive brass cage. The large number of rollers and their mutual angular displacement in rows on both sides of the cage ensure high bearing capacity and proper bearing stiffness as well as high accuracy of shaft rotation.
For users of machining machines such as boring machines, milling spindles, we invite you to submit service requests regarding your own machine park. We are a manufacturer of bearings made in the highest precision class, and among our customers there are also machine services.
Bearings of the NNU 49 K series, with very low cross-sectional height, provide a higher degree of stiffness than the NN 30 K series bearings, but have a slightly lower load capacity. Bearings of the NN 49 K series are equipped with three integral rims on the outer ring and have no rims on the inner ring.
