Adding linear motion to articulated robots extend both their flexibility and work envelope. The 7th axis tracks that enable this linear motion all provide the same functionality but differ in one significant design feature: the antifriction bearing system used to support and guide the tracks.
Track buyers can select systems incorporating one of two primary options: cam followers or profile guides. This white paper explores how these systems differ in regard to function, installation, mainteneance and lifecycle outlay.
