Extruded rail (R2) made of aluminium alloy used to support a shaft (A) intended for a linear guidance system, of the type formed of a body of vertical appearance including, on its upper face, a longitudinal cut (2) for receiving the said shaft (A) along two generatrices, and at its base (1) a pair of symmetrical longitudinal flanges (3') for resting on a fixed supporting structure, characterised in that the said flanges (3') are shaped so that they bear on the supporting structure (B) only via the smallest possible surfaces (E2). <IMAGE> |
