The straight sliding bearing and a straight sliding table according to the present invention are formed so as to m the frictional resistance occurring when a slide block (1) is moved slidingly on a track base (2), by pressing the side surfaces of rollers (4a) by a braking plate (5) which is adapted to be moved in accordance with the pressure of a fluid, and suppressing the rolling of the rollers (4), (4a) by utilising the frictional force generated by this roller pressing operation. Since a predetermined level of rigidity can be obtained in the axial direction as well of the track base by arbitrarily increasing and decreasing the sliding resistance, the sliding bearing and sliding table enable a high precision machined product to be obtained when these sliding devices are used in a mechanical apparatus, such as a machine tool. |
