PURPOSE:To simplify the control for the height and pre-pressure of a slide table by acting the pressing force directed from the fixing portion side to the horizontal portion side upon the upper portion of the slide table from the moving member side in case of fixing the slide table to the moving member. CONSTITUTION:A roller bearing comprises a slide table 1, a roller guide 4, a raceway tube 5, and rollers 6 circulating in a roller endless raceway. The slide rable 1 is fixed to a moving member 20 by a fixing bolt 7, and an adjust bolt 26 fastened from the moving member 20 side is pressed from the fixing portion 2c side to the horizontal portion 2a side. Thus, the height of the upper surface of the horizontal portion of the slide table and the pre-pressure thereof can be simply adjusted according to its use. |
