Abstract
In a slide actuator, a central guide rail having V-shaped grooves defined therein and opened at 90 degree angles, is mounted on a cylinder body. A slide table is brought into engagement with the guide rail. Guide members having V-shaped grooves defined therein are provided inside the slide table so that they are opposed to the grooves defined in the guide rail. Cylindrical roller bearings are alternately fitted at inclinations of 90.degree. in their corresponding channels defined by the opposed grooves. Thus, when the roller bearings are rolled, the slide table is displaced with higher accuracy and a load supported by the slide table is transmitted to the guide rail from the roller bearings.
