JESENTECH customization of precision cantilever Shaft by One-end external thread buckle ring grooved for

Application of cantilever Pin in Industrial Automation parts:

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).

Cylindrical bore bearings are usually hot-fitted, with an interference fit to reduce bearing clearance or to pre-tension the bearing. For the NNU49 series bearings that can be separated from the inner ring, the main shaft is usually mounted on the main shaft and then the raceway is finished to improve the spindle rotation accuracy.
