The Festo DGST-20-30-PA is a double-acting slide unit actuator designed for short, guided linear movements in automation systems. With a 20 mm bore and a 30 mm stroke, it is commonly used where space is limited but precise, repeatable motion is required. It operates using compressed air and provides controlled forward and return movement. This actuator is typically installed in compact machinery where reliability and positioning accuracy matter more than speed or long travel distance.
The DGST slide unit features integrated guidance to help keep the load aligned during movement. This reduces side play and improves repeat accuracy compared to standard pneumatic cylinders without guidance.
This unit is commonly used in pick-and-place systems, small assembly stations, and light handling tasks. Its compact body allows it to fit into tight mechanical layouts without requiring a redesign of the entire system.
It is usually selected when a short, guided stroke is needed rather than long travel or high force.
