Gluing individual modules creates multiple units, such as 2-fold, 3-fold, 4-fold or even 5-fold units. The profiles are either mounted on a common base plate and partially glued or only glued to each other in a fixture. Our Mechanical Linear Units HSB-beta® form the basis for most special solutions in this field. Multiple units with toothed belt drive or spindle drive are possible, also in combination with guide units. In the area of spindle units, units have already been realized in which up to 10 independently driven slides are used. Linear units with double spindle drive are also used here
