Because air cylinders produce fast, repeatable motion, achieve high cycling rates, and don’t generate substantial heat, they are well suited to factory automation systems. However, air is compressible—which is an advantage in many applications, but complicates closed-loop motion control. A solution often overlooked is to incorporate a closed hydraulic circuit to regulate speed and provide load holding for the otherwise all-pneumatic system. Air-over-oil systems offer a cost-effective alternative for many closed-loop speed control applications by combining the convenience of readily available compressed air for power with hydraulics to control motion. These unconventional systems are well suited to low-power systems where smooth speed control, rigidity, or synchronized motion are needed. Most components needed for air/oil systems are standard hydraulic and pneumatic products—but no hydraulic pump is needed. When greater force is needed, a pneumat...
