Abstract: In a slide gage, a slide (16) is guided displaceably by means of four sliding elements (30, 32, 34, 36) arranged in pairs on both sides of a guide rail (10). The two sliding elements (32, 36) located diagonally opposite one another and absorbing the torque transmitted to the slide (16) by a measuring leg (18) during a measuring operation are supported rigidly on the slide, while the remaining two sliding elements (30, 34) are supported resiliently on the slide. This guarantees both a high measuring accuracy and easy movability of the slide (16) on the guide rail (10).
