ABSTRACT:
There is a holding device of a rolling bearing for rectilinear motion in which a plurality of rolling members such as balls or rollers are rectilinearly arranged at regular intervals in track grooves or track surfaces. This holding device has a rectangular plate-like shape made of a plastic material. Many windows are formed at regular intervals in the longitudinal direction of the holding device. Each window is formed so as to have the relation of S<L<D<E (where, S and L are outside diameters on both sides of the window and E is an inside diameter thereof and D is a diameter of each ball). The outside diameter of the adjacent windows in the same side surface of the holding device differ. This holding device is manufactured by injecting and molding a plastic material into the rectangular molding die at high pressure and high temperature. In this case, many barrel-shaped window pins are disposed in the cavity of the die at regular intervals in its longitudinal direction. Thereafter, the window pins are alternately pulled out one or two at a time in the opposite directions. With this method, an economical holding device having small slide friction and resistance can be easily manufactured. Also, the balls or rollers are difficult to drop out of the holding device.
