A journal for a bearing of a precision slide system comprising a support having a blind bore with connecting means in the form of a screw or bolt adapted to secure the support in the journal having a head of complementary shape to a rebate of the journal, and means to bind the journal and screw or bolt together. The blind bore has a rebate therein and the screw or bolt is adapted to be accommodated in the rebate and adapted to connect the bearing and support whereby there is a substantially flush surface across the support and connecting means. The bore has a female thread and the rebate has a frusto-conical shape, and is carried by a ball race of the journal, which ball race is mounted on a second one (FIG. 1), which in turn rests on a nut, the support passing through the nut to be secured to a base or machine plate (FIG. 5). The bearing is formed of two vertically (as shown) mounted wheels which form a 70 DEG V-groove for receiving the edge of a slide of the system.
