About the Airtac ACA Standard Automatic Compensation Hydraulic Shock Absorber ACA2030-1
The ACA2030-1 combines a 30 mm stroke with speed type 1 and the standard plastic cap in the AirTAC ACA20 family. Its fully threaded M20x1.5 body screws straight into the frame and sheds impact heat well, while self-compensation lets the resistance adjust itself to each impact without external setting.
Speed type 1 covers fast, light loads at up to 4 m/s with a maximum moving mass of 280 kg. Per cycle it absorbs up to 70 J and 58000 J per hour, and the unit weighs just 210 g. The hardened stainless steel piston rod resists impact and corrosion, and operation is rated from -5 to +70 C.

How to choose
Pick -1 over ACA2030-2 (medium speed, up to 2 m/s) and ACA2030-3 (low speed, heavy loads, up to 1 m/s) whenever your load arrives fast but light; if it rebounds at the start of the stroke you may need a faster type, and if it rebounds at the end a slower one. On stroke, 30 mm sits between ACA2025 (65 J per cycle) and ACA2040 (80 J per cycle), and AirTAC recommends running between 20% and 80% of the maximum energy. For the same 30 mm type 1 unit with a different strike face, order ACA2030-1N (no cap) or ACA2030-1F (steel cap).
Applications
Pick-and-place gantries
Fast, light end-of-travel damping on axis carriages moving at up to 4 m/s, with the plastic cap cushioning contact against lightweight strikers.
Conveyor divert and stop positions
Decelerates lightweight carriers and pushers on accumulation lines within the 280 kg type 1 mass window, keeping cycle rates high.
Fast sliding guards
Takes the kinetic energy of quick-moving machine doors and guards, absorbing up to 70 J per cycle and 58000 J per hour.
FAQ
What are the key figures for the ACA2030-1?
30 mm stroke, M20x1.5 body thread, speed type 1 rated to 4 m/s, maximum moving mass 280 kg, 70 J per cycle and 58000 J per hour, 210 g weight, -5 to +70 C, side load 3 degrees or less.
Can the end of the stroke work as a hard stop?
Yes. A stop nut, available as an accessory, lets the stroke end act as a positive stop, and AirTAC recommends stopping the load 1 mm before the rod bottoms out to maximize service life. A flange is also available for mounting.
