The present invention relates to an error-compensating bearing screw conveying device including: a screw shaft having a screw mounted along the outer circumferential surface thereof; a nut body adapted to fittedly insert the screw shaft thereinto along the inner circumferential surface thereof and having a plurality of mounting holes formed along the outer circumferential surface thereof in such a manner as to conform to a spiral passageway formed on the screw of the screw shaft; and a plurality of radial bearings mounted in the mounting holes of the nut body and adapted to be rotated at the fixed positions thereof in such a manner as to come into contact with the outer circumferential surface of the screw of the screw shaft along the outer races thereof when the screw shaft or the nut body is rotated; and position-adjusting means mounted on the top sides of the radial bearings so as to adjust the positions of the radial bearings in such a manner as to be oriented toward the center of the screw shaft. |
