    • The present invention concerns a slider of a rectilinear guide unit for guiding a movable body such as a work table of a machine tool, an industrial robot or the like by moving along a track rail arranged on a stationary section such as a bed or a column while bearing a load. Such type of slider is manufactured by injection-molding a synthetic resin over a metallic block main body having ball load rolling surfaces. Further, the block main body is provided on the outer side surfaces thereof with synthetic resin side surface molded portions with ball return holes formed by padding and on the front and rear end surfaces thereof with end surface molded portions with change direction paths for balls formed by padding. Further, simultaneously with the padding of the side surface molded portions and the end surface molded portions, there is formed by padding an upper surface molded portion on the upper surface of the block main body so as to connect the end surface molded portions formed on both end surfaces of the block main body, respectively.

    • A linear guide device which comprises a track bed having a substantially rectangular section opened at one side and is provided at its inner surfaces with rolling surfaces for rolling members; and a bearing block which has load rolling surfaces cooperating with the rolling surfaces to hold the rolling members therebetween and moves in a hollow portion of the track bed in accordance with rotation of a feed screw shaft engaging the bearing block. The bearing block is formed of a block body, rolling aperture forming plates and covers which are jointed together to entirely form ball circulation paths through which no-load balls circulate. Therefore, a long bearing block can be facilely manufactured, and thus a number of the rolling members can be increased for achieving the linear guide device having a large maximum allowable load and a compact configuration.
