75 15 Configuration of the Base Structure 15.4 Configuration of the Base Structure 15.4.4 Parallelism Tolerance of the Reference Surfaces for MINIRAIL and MINISCALE PLUS Guide rails which are not aligned in parallel cause unplanned loads in the guide system over its stroke length, subsequently subjecting the tracks to additional stress. This decreases running accuracy of the guideways and can shorten the service life. The parallelism tolerances Δ below must therefore be adhered to.
