<p>The invention relates to movable bearing devices, in particular to ball bearings which are usable in the form of machine and machine-tool bearing elements. The promising sector for using the inventive ball bearing is the furniture production. Said invention is characterized in that the use of the ellipsoid-shaped bearing surface of the cavity of the ball bearing body and the embodiment of said ball bearing and a layer of small balls of a resilient elastic material totally prevent the sealing and consequently blocking in the small ball layer and contribute to the reliable operation of the ball bearing.</p>
