Abstract: A sliding block with adjustable track positioning comprising a prismatic body, in one face of which there is a longitudinal recess arranged to receive a rail by way of rolling elements positionable in respective tracks, the body being essentially of C-shaped cross-section consisting of a central part from which two flanges extend, wherein in at least one of the two flanges of the C-shaped cross-section there is provided a second longitudinal recess which divides it into separate portions connected together at the central part, the second recess containing elements for adjusting the distance between the two separate portions.

Abstract: Linear sliding guides with rolling elements for translating couplings or the like, which include by a pair of contoured elements suitable for being fitted one with the other wherein rolling elements are interposed between the contoured elements, and wherein both of the contoured elements are provided with seats for at least partially housing the rolling elements. The rolling elements are retained by an intermediate cage element. Inside the seats the contoured elements have at least one mutually opposite face treated by high-thickness hard anodizing. The rolling elements are made of a plastic material and the contoured elements are manufactured from an extruded light alloy material.

Abstract: A sliding unit adjustable within wide limits for operating machines comprising at least one hollow guide made from an extruded structural shape installed inside supporting elements equipped with revolving elements, which cooperate with sliding surfaces of the hollow guide, with the support elements being positioned on portions of a base plate which can be adjusted both in height, and in the transversal direction relatively to said hollow guide.

Abstract: In a sliding unit for machine tools and/or portions of them, essentially comprising guides and supports, the ones being sliding relatively to the others and vice-versa, the guides are extruded hollow section bars with octagonal cross section, made of light alloy, and the supports bear rolling means, which cooperate with opposed surfaces of said guides.
