ABSTRACT:
In this rolling guide unit, a slide is placed on a track rail so that the slider can be moved slidingly in a linear direction, and a shaft portion is provided on the upper surface of and integrally with the casing of the slider, and has an annular raceway surface on the circumferential side thereof, lower and upper rotary bodies being fitted firmly and rotatably around the shaft portion. The casing constitutes a common part having a function of making a linear movement and a function of making a rotational movement, and this enables the height of the rolling guide unit to be reduced to as great an extent as possible, and an accumulated error due to an assembling operation to be minimized, whereby a highly accurate guide machine can be provided.
