ABSTRACT:
A sliding roller bearing with a height adjustor for supporting a column section in vertical type machines such as electro-spark erosion machines and a slide section in industrial machines. The roller bearing comprises a number of balls received between a bearing body and a retainer, and a track shaft received in the bearing. The bearing body is formed in its upper flat surface with a tapered groove in which a tapered gib having a flat upper surface and a lower surface conforming to the bottom of the tapered groove is received for sliding movement. The tapered gib has a threaded hole extending centrally and longitudinally therethrough. An adjusting bolt is threadedly engaged with the threaded hole and is formed at its one end portion with a male screw having a pitch larger than that of the threaded hole. The male screw is threadedly engaged with a flange of the bearing body so that the rotation of the screw in either direction causes the lateral movement of the rib which in turn results in the change in the bearing height.
