Telescoping slide made of an extruded bar of aluminium.

摘要: The rail comprises extruded aluminium profiled sections overlapping to form at least two ball guide tracks. A closed hollow inner section (4) fits into the outer (1). and/or have longitudinally aligned open function channels (3,5,8). can a concave curvature which be compensated by balls (2) guided in tracks (6,7). running track series with insertion of spacers formed plastics rods whose diameters are smaller than those balls.
