Abstract

PURPOSE: To perform the elevating operation of a ram rod smoothly and accurately by arraying specific concave grooves on the outside circumferenial surface of the ram rod the inside circumferential surface of a bushing, and and rolling balls in a linear contact state along with these.
CONSTITUTION: Concave grooves 5, 6 of an arc shape in section are arrayed on the outside circumferentail surface of a ram rod 1 of a dining press and the inside circumferentail surface of a bushing 2 of a bearing guiding the rod 1 in the vertical direction, longitudinally parallel in the positions fitting to the respective balls 4. The radii of curvature R1, R2 of the grooves 5, 6 are made slightly larger than the radius R of the balls 4, for example, about 5W8% larger. As a result, the contact between the balls and the ram rod and bushing is no longer point contact, and the abrupt expanion of the gaps between these is prevented despite long-time use.
