For a linear guide (10), two shafts (20) are braced against one another, with line contact, on a support (12) by means of screws (24), at an angle ( alpha ) relative to one another. As supporting bodies (30) use is made of aluminium parts with an integral supporting profile (14), the flute (26) of which is made into a filleted step (28) by a ridge (16). A screw hole (42) is inclined at an acute angle to a counter-hole or a pair (44) of holes, the said counter-hole or pair of holes being arranged in mirror symmetry. Abutting shaft ends can be braced on individual bodies (30) against a continuous shaft, fixed at the central hole (32), by screw fastening at the pair (44) of counter-holes. A continuous rail body with spaced groups (40, 41) of screw holes can form part of a hollow box section (64). In a three-chamber system (70), hollow sections (64) with an inner rail body (30) adjoin a central cavity (71) externally. At least one drive moves a carriage (49) which rests by four linear rows (54) of balls or four rollers (55) on the shaft outer surfaces (21) and can carry a slide for zip-fastener-type sealing lips (61) which are self-closing and are situated on an open side of the hollow section (64). …<IMAGE>… |
