High Precision Low Noise NN3019 NN3020K Double Row Cylindrical Roller Bearing
Description,
In the application of machine tool spindles, double-row precision cylindrical roller bearings
are also used, usually combined with precision angular contact ball bearings or thrust bearings.
These bearings can withstand large radial loads and allow higher speeds. The two rows of rollers
in a metal-machined online bearing are arranged in a crossed manner, and the frequency of fluctuation
during rotation is significantly higher than that of a single row bearing, and the amplitude is reduced by
60% -70%. This type of bearing usually has two forms: NN30, NN30K two series of bearings with flanges
on the inner ring, the outer ring can be separated; NNU49, NNU49K two series of bearings with flanges
on the outer ring, the inner ring can be separated, of which NN30K and NNU49K series The inner ring is
a tapered hole (taper 1:12), which cooperates with the tapered journal of the main shaft. Moving the inner
ring axially can expand the inner ring, so that the bearing clearance can be reduced or even the bearing can
be pre-tensioned (negative clearance). status). Cylindrical bore bearings usually use hot-fitting, using
interference fit to reduce bearing clearance, or pre-tensioning the bearing. For NNU49 series bearings
with separable inner ring, the raceway is usually finished after the main shaft is mounted on the inner
ring to improve the rotation accuracy of the main shaft.
