Abstract: The present invention relates to a bearing device particularly intended to be used in the type of poker vibrator whose rotor shaft (2) exhibits an eccentric arranged between two needle roller bearings (3,4). Besides being carried in these bearings, the rotor shaft (2) is also carried in a deep-groove ball bearing (5) intended to take up any axial forces acting on the rotor shaft. In order to relieve it from radial forces, the deep-groove bearings (5) is mounted in accordance with this invention with a positive clearance in both the radial and axial directions. The radial clearance can thereby be provided either between the deep-groove ball bearing's outer race (6) and the bearing sleeve (7) or between its inner race (8) and the rotor shaft (2). The purpose of the axial clearance is to permit the radial movement of the deep-groove ball bearing (5) that is the purpose of the radial clearance.
