Sliding block with adjustable track positioning

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, said body being essentially of C-shaped cross-section comprising a central part from which two flanges extend, characterized in that in at least one of said flanges of said C-shaped cross-section there is provided a second longitudinal recess which divides it into separate portions connected together at said central part, said second recess containing adjustment elements for adjusting the distance between said two separate portions, said adjustment elements comprise screws arranged transversely to said two separate portions and acting to bring said two portions further apart or closer together, said screws pass through a seat provided in a first of said two portions and are screwed into a threaded second seat in the other of said two portions, a longitudinal eccentric shaft inserted within a relative profiled housing provided in facing surfaces of said two portions and interacting with said transversely arranged screws.
