Genuine AirTAC hydraulic shock absorber, order code ACA2030-1F from the ACA20 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
ACA2030-1F is the steel-cap (F) build of the 30 mm, speed type 1 member of the AirTAC ACA20 series. The F option replaces the plastic cap with a steel cap for heavier impacts on the strike face, useful where bumpers or machine strikers press hard against the absorber.
Type 1 tuning suits fast, light loads up to 4 m/s with a maximum moving mass of 280 kg, and the 30 mm stroke absorbs up to 70 J per cycle at 58000 J per hour. The M20x1.5 threaded body mounts and adjusts easily and dissipates heat well; the piston rod is hardened stainless steel, and the working range is -5 to +70 C with side loads kept within 3 degrees.

Within the 30 mm family the choice is mostly about the cap and the speed type: choose ACA2030-1 for the plastic cap or ACA2030-1N for a capless body where your machine supplies its own striker. If the load is slower or heavier, type 2 (ACA2030-2, up to 2 m/s) or type 3 (ACA2030-3, up to 1 m/s) hold more mass; a shorter ACA2025 or a longer ACA2040 shifts the energy budget from 65 to 80 J per cycle.
The steel cap stands up to repeated hard contact from metal strikers on slides and carriages, within the type 1 limit of 4 m/s and 280 kg.
End-of-travel damping for light shuttle carts and small vertical lifts that arrive quickly and land on a steel-faced stop.
Absorbs the snap of fast pneumatic pushers up to 70 J per cycle, with the steel cap tolerating metallic contact faces.
30 mm stroke on an M20x1.5 threaded body, speed type 1 for impact speeds up to 4 m/s, maximum moving mass 280 kg, absorption of 70 J per cycle and 58000 J per hour, unit weight 210 g, temperature -5 to +70 C.
It adds a steel cap for heavier impacts in place of the plastic cap; the hardened stainless steel piston rod and the 3 degree side-load limit are unchanged. Confirm cap dimensions from the datasheet.
