About the Airtac ACED Double-acting Compact Cylinder ACED25X5
The ACED25X5 is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format: a 25 mm bore with just a 5 mm stroke, a rod exiting both covers, and equal output force in each direction because both strokes work on the rod-side area. At 0.5 MPa it delivers 206.2 N either way, rising to 288.6 N at 0.7 MPa, with a peak of 42 kgf at 1.0 MPa. The through-rod resists rotation and light side load, and the rear rod end gives you a free mounting point or a sensor-flag carrier.
The hard-anodized aluminium body with a roller-burnished bore and an S45C hard-chrome-plated rod keeps wear low over millions of short cycles, while fixed TPU bumpers absorb end-of-stroke shock at both covers. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped fixtures a full-length body cannot reach. Running 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, it lifts roughly 10 kg vertically once you halve the 21 kgf thrust equivalent for a 2:1 margin. Position sensing needs the optional -S magnet code; without it no CMSE or DMSE switch can be fitted.

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 (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 ACED25X5 Is Used
Micro clamping on CNC fixtures
The 5 mm stroke and 206.2 N clamping force (about 124 N usable at a 0.6 margin) make the ACED25X5 ideal for clamping small aluminium brackets or PCB fixtures on a machining table where every millimetre of height counts.
Part-present ejection on assembly lines
A short push to seat a bearing or release a part from a nest: the double rod keeps the pusher square without guides, and the rear rod can carry a flag for the optional -S magnet with a CMSE switch.
Fine height adjustment in test rigs
Equal force both directions lets the same cylinder raise or lower a sensor head or gauge pin by 5 mm with repeatable 288.6 N at 0.7 MPa, fitting inside the tight gantry of an automated inspection station.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X5 the Right Cylinder?
At 206.2 N per direction at 0.5 MPa, the 25 mm bore sits between the 20 mm (117.8 N) and 32 mm (345.6 N) options - step down for light clamping, up if your jig needs over 300 N. The 5 mm stroke suits ejection, part-present and fine-adjust duties rather than long transfers. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. Order the -S code if you want CMSE / DMSE switching, and pick FA flange, LB foot or CA clevis plus I/Y rod knuckles to bolt straight onto the ISO 21287 face. Female M6x1.0 rod thread and M5x0.8 ports come as standard on this bore.
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 ACED25X5 FAQ
Yes - the double-rod design puts a piston rod out of both covers, so both strokes use the rod-side area and force is equal either way: 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um, and -20 to +70 C temperature.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow jigs and guards. Sensing is not fitted as standard: order the optional -S magnet code and CMSE or DMSE switches can then ride the body's magnet slots. A fixed TPU bumper at each end absorbs end-of-stroke shock, and FA flange, LB foot or CA clevis mounts plus I/Y rod knuckles bolt directly to the ISO 21287 face.
