For application with two parallel guide systems, one side must be designed as floating bearing. There is a suitable fixed-/floating-bearing solution for every installation location, whether it be horizontal, vertical or lateral. This installation method prevents a sluggishness and/or a jamming of the guide with parallelism deviations between the guides. The floating bearing can be implemented by a controlled extension of the clearance in the direction of the estimated parallelism error. Thus an additional degree of freedom arises on one side.
During installation, take care that the floating bearing has the same clearance on both sides. You can see the version of the fixed/floating bearing system recommended by us in the designs given in the individual sections of the systems. The mounting surfaces of the rails and carriages should possess a good evenness (e.g. machined surface) to prevent twisting in the system. Smaller unevennesses in the mounting surfaces can be compensated up to a certain measurement by the floating bearing.
