Abstract

A bearing unit comprises a first shaft carrying the bearing proper, a second shaft extending coaxially at least partly within the first shaft and cooperating with the load, and a shaft coupling device which engage the two shafts with each other in both the axial and the radial direction. The device can be disengaged if the second shaft is exposed to an undesirable load, such as impacts or vibrations, in order to protect the bearing proper.
