Airtac ACED Double-acting Compact Cylinder ACED125X5S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X5S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 5mm 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 ACED125X5S
A double acting ISO 21287 compact cylinder with a rod leaving both covers, the ACED125X5S delivers 5890.5 N in each direction at 0.5 MPa because both strokes work on the rod-side area. The 5 mm stroke suits short clamp-and-confirm moves where a full-length body would never fit; the hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The 25 mm hard-chrome-plated S45C through-rod resists rotation and side load, and the rear rod can carry a sensor flag or a second tool. At 0.7 MPa the output rises to 8246.7 N both ways. As a rule of thumb, keep real work near 3534 N at 0.5 MPa, which is roughly a 300 kg vertical lift with a 2:1 margin. A fixed TPU bumper sits at each end, and the fitted -S magnet accepts CMSE / DMSE switches for end-position sensing.

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 ACED125X5S Is Used
Press-head bump stroke
The 5 mm stroke and 5890.5 N per direction let a stamping fixture seat a part in a die with a short, symmetric push-pull cycle at 30-500 mm/s.
Clamp-confirm on a CNC fixture
Both rods move together, so a machinist mounts a work-support plunger on one end and a CMSE switch flag on the other to confirm clamping of a steel billet.
Pallet-stopper on a heavy conveyor
With about 300 kg of vertical lift capability at a 2:1 margin, the cylinder raises a stop blade under pallet loads on a warehouse transfer line.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X5S the Right Cylinder?
For this force class, drop to an ACED80X5 (2356.2 N at 0.5 MPa) when the load is lighter, or step up only if you exceed the 8246.7 N available here at 0.7 MPa. Note that a plain double-rod cylinder drifts when air is lost; add a rod lock or pilot check if the press or clamp must hold position. Mount with FA/FB flanges, LB feet or FTC brackets plus I/Y rod knuckles on the ISO 21287 face, and specify the G thread option if PT ports do not match your plant.
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 ACED125X5S FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal push and pull. At 1.0 MPa the peak output is 1201.3 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, on air filtered to 40 um.
The S in ACED125X5S means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be slid into the body slots for end-of-stroke signals. The compact ISO 21287 body is hard-anodized aluminium with threaded covers, a 25 mm hard-chrome S45C rod, fixed TPU bumpers at both ends, a female M16x2.0 rod thread, a 1/4" PT port, and a 300 mm max standard stroke for this bore.
