Genuine AirTAC hydraulic shock absorber, order code ACA2030-2F from the ACA20 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
Speed type 2 places the ACA2030-2F in the middle of the ACA20 speed ladder, accepting impacts up to 2 m/s where type 1 units (4 m/s) would run too soft and type 3 units (1 m/s) too firm. Across the 30 mm stroke it absorbs 70 J per cycle and up to 58,000 J per hour, with an effective-mass ceiling of 780 kg that rises to 1120 kg if you switch to the slow, heavy-load type 3.
The F suffix orders a steel cap on the rod end, the catalog's answer for heavier impacts: the blow lands on steel instead of the plastic cap fitted to the plain ACA2030-2. The one-piece M20x1.5 threaded body sheds heat well, the hardened stainless piston rod resists impact and corrosion, and the unit weighs 210 g and runs from -5 to +70 C.

Choose ACA2030-2F over ACA2030-2 when impacts are heavy enough to chew a plastic cap, and over the capless ACA2030-2N when the rod end should carry a defined striking element rather than bare steel. The 30 mm stroke suits loads within its 70 J per cycle rating; step down to ACA2025-2 (65 J) for compact machines or up to ACA2040-2 (80 J, 1280 kg at type 3) for heavier axes. A flange and a stop nut are available as accessories for setting the strike point.
Cushioning clamping arms and fixtures that land hard on steel parts, where the steel cap stands up to repeated heavy strikes the plastic cap is not meant for.
Fitting automated guided vehicles or lift tables that dock at medium pace, sized against the 2 m/s type 2 rating and the 780 kg effective-mass ceiling.
Stopping indexing pallet tables at their end position; the stop nut accessory turns the last millimetre of stroke into a defined stop 1 mm before bottom-out.
Stroke 30 mm, M20x1.5 body thread, speed type 2 for impacts up to 2 m/s, 70 J absorbed per cycle at up to 58,000 J per hour, effective mass up to 780 kg, weight 210 g, operation from -5 to +70 C, side load within 3 degrees. The F suffix adds the steel impact cap.
The cap is a selectable ordering option, so you can move between the plastic cap of ACA2030-2, the steel cap of ACA2030-2F and the capless ACA2030-2N in the same 30 mm body. A stop nut and a flange are offered as accessories, and the fully threaded M20x1.5 body lets you re-set the mounting depth at any time.
