The present invention relates to a smoothing shaft bearing screw conveying device to attach and join a smoothing shaft without a screw and a radial bearing joined to a nut to each other on a helical or spiral path in order to convert the rotary power of the smoothing shaft to the thrust power of the nut or a movable block joined to the nut. The smoothing shaft bearing screw conveying device comprises: the smoothing shaft having a circular cross section with a smooth outer circumference; the radial bearing of which the outer wheel is arranged on the surface of the smoothing shaft in a helical direction; and a bearing support to press and support the radial bearing in the direction of the smoothing shaft with power which is adjusted not to cause a slip between the surface of the outer wheel of the radial bearing and the surface of the smoothing shaft when the smoothing shaft rotates. |
