Airtac ACED Double-acting Compact Cylinder ACED125X225S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X225S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 225mm stroke, 1/4" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACED Double-acting Compact Cylinder ACED125X225S
A double acting compact cylinder built to ISO 21287, the ACED125X225S pushes a 125 mm piston through a 225 mm stroke with a 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. That through-rod also resists piston rotation and side load, and the rear rod makes a handy mounting point for a sensor flag or a second tooling plate.
The hard-anodized aluminium body with an S45C hard-chrome plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 125 mm bore fits presses and gantries that cannot spare the length. Fixed TPU bumpers sit at both ends, and the fitted -S magnet lets CMSE / DMSE switches report position. At 0.5 MPa the thrust equals roughly 600 kg, so planning around 300 kg of vertical lift keeps a comfortable 2:1 margin.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. 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 ACED125X225S Is Used
Heavy stamping press head
The 5890.5 N thrust in both directions drives a stamping or coining head on a short-stroke press, where the compact body fits inside a guarded frame that a full-length profile cylinder cannot.
Pallet clamp on a transfer line
Equal force both ways clamps and releases pallet fixtures on an automotive transfer line, with the through-rod keeping the clamp plate square under off-center loads.
Gantry lift-and-lower module
A rear-exit rod balances the mount on a gantry Z-axis lifting castings of about 300 kg, while CMSE switches on the fitted magnet confirm top and bottom of the 225 mm stroke.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X225S the Right Cylinder?
At 5890.5 N per direction, this is the top of the ACED range; step down to the ACED100 (3769.9 N at 0.5 MPa) for lighter clamping, or stay here if your load needs the full 125 mm bore. Note that a plain double-rod cylinder drifts when air is lost, so pair it with a rod lock or pilot check valve if the load must stay put. The 225 mm stroke sits inside the 300 mm standard maximum for this bore, and FA/FB flanges, LB feet, FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face. The -S magnet is already fitted on this code, so CMSE / DMSE switches can be added without reordering.
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 ACED125X225S FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal either way: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, peaking at 1201.3 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the port is 1/4" PT with an M16x2.0 female rod thread.
The -S magnet is fitted on this code, so AirTAC CMSE reed or DMSE solid-state switches clamp into the body slots to signal end positions. FA/FB flanges, LB feet, FTC brackets and I/Y rod knuckles attach to the standard ISO 21287 face, and the fixed TPU bumpers at each end simply soften the stroke ends - they do not hold or brake a load.
