The utility model is mainly used for fixing a tapered hole bearing on a cylindrical journal of a stepped shaft. The unloading sleeve is pressed between the bearing inner ring and the shaft which is arranged on the shaft shoulder or a similar fixing device. Since the end of the thread can be based on the actual application of different sizes, because the shaft end of the thread can be based on the actual application of different sizes, so the lock nut or end plate is not supplied with the back off the sleeve. You can use the KM or HM lock nut with the appropriate locking device (lock nut), but must be ordered separately.
It is necessary to overcome the friction between the bearing and the unloading sleeve and the mating surface between the shaft and the unloading sleeve to press the unloading sleeve into the bore of the bearing. In order to facilitate the installation and removal of the bearing on the unloading sleeve, SKF recommends the use of hydraulic nut.
