Although pneumatic is widely used in automation systems, it is observed that the use of electromechanical driven systems has become widespread today. There are many different types of electromechanical systems. Generally, the motion transfer is provided by controlling the servo motor, the rotational motion is converted into linear motion with the system elements used as screw ball, toothed belt driven etc. In addition to the advantages such as being easy to control, high positioning accuracy, and long-term maintenance, the biggest disadvantage in the preference of this type of system by the user seems to be the high initial investment costs. However, while the initial investment cost comes to the fore in product selection, the necessity of evaluating parameters such as energy consumption and maintenance generally remains in the background. In this study, the evaluation of a long-stroke rodless-cylinder pneumatic system and a toothed belt-driven electromechanical system in terms of initial investment, maintenance and predicted energy consumption cost during its lifetime were examined with different operating scenarios and comparatively evaluated. Experimental and theoretical calculations were made and evaluated considering the equivalent load, stroke, and annual operating and usage time in both systems moving in the horizontal direction. It has been seen that the initial investment cost of the servo motor, the supply pressure, the number of cycles, the standby time are important and should be considered in the costing of the systems.
