Airtac ACED Double-acting Compact Cylinder ACED25X70
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X70 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø25mm bore and 70mm stroke, M5×0.8 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 ACED25X70
The ACED25X70 is a double acting ISO 21287 compact cylinder with a piston rod leaving both covers, so the 25 mm bore delivers the same 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) on every stroke. The through-rod resists rotation and light side load, and the free back-end rod is a handy place to carry a sensor flag or a second tooling plate.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it drops into tight jigs and guarded gantries. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the S45C hard-chrome rod keeps wear low. Plan on roughly 124 N of real work at 0.5 MPa, which lifts about 6 kg vertically with a 2:1 margin. Speed range is 30-500 mm/s; the optional -S magnet enables CMSE / DMSE switches.

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 ACED25X70 Is Used
Symmetric jig clamping
The through-rod lets a fixture clamp from either end with equal 206.2 N force, ideal for palletized machining jigs where both faces must grip identically.
Pusher on a packaging line
With 288.6 N at 0.7 MPa and speeds up to 500 mm/s, the ACED25X70 pushes cartons between conveyor lanes in the compact space a short-body cylinder needs.
Sensor-flag test station
The rear rod can carry a flag for CMSE / DMSE switches (with the optional -S magnet), giving end-of-stroke confirmation on a 70 mm verification slide.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X70 the Right Cylinder?
At 206.2 N per direction, the 25 mm bore suits clamping and positioning of small-to-medium fixtures. Step down to the 20 mm bore (117.8 N at 0.5 MPa) for lighter gates, or up to the 32 mm bore (345.6 N) when a heavier press-fit or lift is needed. Remember the piston drifts if air is lost - add a rod lock or pilot check where a load must be held. Mount with FA/FB flange, LB foot or FTC brackets, and order the -S code if CMSE / DMSE position switches are planned.
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 ACED25X70 FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so output is equal each way: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, with a maximum of 42.0 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 70 mm stroke sits well inside the 150 mm maximum standard stroke for this bore.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, with a fixed TPU bumper at each end to absorb end-of-stroke shock. Position sensing requires the optional -S magnet at ordering; only then can CMSE / DMSE switches be mounted on the body slots. Without the -S code no magnet is fitted.
