About the Airtac ACED Double-acting Compact Cylinder ACED125X75S
A heavy-duty double acting compact cylinder built to ISO 21287, the ACED125X75S pushes a 125 mm bore through a 75 mm stroke with a piston rod leaving BOTH covers. Because each side of the piston sees the rod-side area, output is identical in either direction: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal push and pull. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag or a second tool. The S code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches mount directly in the body slots.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 125 mm bore has to fit inside a press frame or a guarded gantry. The hard-anodized aluminium body carries a roller-burnished bore, the 25 mm S45C rod is hard-chrome plated, and a fixed TPU bumper at each end absorbs end-of-stroke energy. For sizing: at 0.5 MPa the usable work force is roughly 3534 N, and the vertical-lift equivalent is about 600 kg, or roughly 300 kg with a 2:1 margin. Speed range 30-500 mm/s; operating pressure 0.15-1.0 MPa (22-145 psi).

Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø125mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 5890 N |
| 0.7 MPa | 8247 N |
| Max (@1.0 MPa) | 1201 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACED Double-acting Compact Cylinder ACED125X75S Is Used
Heavy press and forming fixtures
With 5890.5 N in both directions at 0.5 MPa, the double rod clamps or ejects in a stamping or forming die where the return stroke needs the same force as the advance, and the 75 mm stroke fits a shallow die set.
Pallet stacker lift assist
The vertical-lift equivalent of about 600 kg at 0.5 MPa (roughly 300 kg at a 2:1 margin) suits lifting heavy pallets or dies; the through-rod keeps the load plate from rotating, and a rod lock holds position on air loss.
Foundry ladle positioning
In a foundry line, the symmetric double-rod mount and rear sensor rod let the -S magnet and DMSE switches flag both end positions, while the hard-anodized body and hard-chrome rod stand up to dusty, hot surroundings.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X75S the Right Cylinder?
At 125 mm this is the top of the ACED range: 5890.5 N at 0.5 MPa both ways, against 3769.9 N for the 100 mm bore. If your load needs less than about 3534 N of real work force at 0.5 MPa, the 100 mm bore saves space and air; if you need the full 1201.3 kgf class at 1.0 MPa, stay at 125. The 75 mm stroke sits well inside the 300 mm max standard stroke for this bore, so it is a catalogue item, not a made-to-order build. Remember that a plain double-rod cylinder drifts when air is lost - for a held vertical load add a rod lock or pilot check valve. Mounting brackets (FA/FB flange, LB foot, FTC) and I/Y rod knuckles bolt straight to the ISO 21287 face; the female M16x2.0 rod thread takes standard rod accessories. PT port thread, 1/4" ports.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACED Double-acting Compact Cylinder ACED125X75S FAQ
Yes - this is a double-rod cylinder, so a rod exits both covers and both strokes use the rod-side area. Force is equal both ways: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, with a maximum of 1201.3 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 1/4" ports take PT thread. The 75 mm stroke is within the 300 mm max standard stroke for the 125 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 125 mm bore fits where a full-length cylinder cannot. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches click into the body slots for end-position sensing. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles bolt to the standard ISO 21287 mounting face. The rod end thread is female M16x2.0.
