Clients customized high precision cantilever Shaft Accord with IATF16949 quality system for assembly line

In the application of machine tool spindles, the cantilever pin external thread mounting and external thread type, double row precision cylindrical roller bearings are also used, usually in combination with precision angular contact ball bearings or thrust bearings. These bearings can withstand large radial loads and allow for higher rotational speeds. The two rows of rollers in the bearing are arranged in an intersecting manner. The wave frequency is greatly increased compared with the single row bearing, and the amplitude is reduced by 60%-70%. These bearings usually come in two forms: NN30, NN30K two series bearing inner ring with ribs, outer ring can be separated;

NNU49, NNU49K two series bearing outer ring with ribs, 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. The inner ring is axially moved to make the inner ring expand. The cantilever pin is embedded in the external thread to install the external thread type, so that the bearing clearance can be Reduce or even pre-tighten the bearing (negative clearance state).
