Claims

[Claims for Utility Model Registration] 1. Consisting of one slide block through which a rotating shaft having a smooth surface passes through the axis, and at least one bearing built into the slide block, the bearing is located on the inner circumferential surface. It has a protrusion in the center that can come into contact with the rotating shaft, and the bearing is slightly rotated around a vertical axis perpendicular to the rotating shaft,
The bearing itself has an inclination angle corresponding to the lead angle of a screw for horizontally moving the slide block in synchronization with the rotational direction of the rotating shaft, and the outer circumferential surface of the outer ring of the direct acting bearing is formed from a spherical surface. A linear drive bearing unit characterized by: 2. A practical application characterized in that a set of at least two of the plurality of direct-acting bearings built into the slide block are arranged axially symmetrically in the direction of contact with the rotating shaft. A linear drive bearing unit according to claim 1 of the patent registration claim.
