Airtac ACED Double-acting Compact Cylinder ACED125X25
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X25 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 25mm 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 ACED125X25
A double acting compact cylinder built to ISO 21287, the ACED125X25 pushes a 125 mm bore through a 25 mm stroke with a piston rod leaving BOTH covers. Because each stroke works on 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. The hard-anodized aluminium body carries threaded aluminium covers, an S45C hard-chrome plated rod, and a fixed TPU bumper at each end to absorb end-of-stroke shock.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 125 mm bore fits heavy presses and clamping stations where a full-length body cannot. In practice, plan on roughly 3534 N (about 360 kgf) of usable work at 0.5 MPa, or expect it to lift about 300 kg vertically with a 2:1 margin. The through-rod resists rotation and side load, and the rear rod can carry a fixture or sensor flag. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).

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 ACED125X25 Is Used
Heavy stamping die clamping
The symmetric 5890.5 N rod-side force clamps large die segments in both directions on a press tooling table, with the 25 mm stroke locking parts inside a shallow fixture.
Billet ejector on a forging line
A through 25 mm rod ejects hot steel billets from a die pocket; the rear rod drives a position flag so operators confirm full return at 30-500 mm/s.
Pallet press platen drive
Mounted flange-down with an FA bracket, the double rod keeps the platen square while pressing cartons, delivering about 360 kgf of usable force at 0.5 MPa.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X25 the Right Cylinder?
At 5890.5 N per stroke at 0.5 MPa, this is the top of the ACED range; step down to ACED100X25 (3769.9 N) for lighter clamping or up from ACED80X25 (2356.2 N) when 125 mm bore force is needed in a short body. The 25 mm stroke is well inside the 300 mm maximum standard stroke for this bore. Note that the piston drifts if air is lost, so add a rod lock or pilot check valve for a held load. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face. This code has no magnet; order the -S version if you need CMSE / DMSE switch sensing.
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 ACED125X25 FAQ
Yes. With a rod exiting both covers, every stroke uses the rod-side area, so output is equal both ways: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, peaking at 1201.3 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, -20 to +70 C, and speed 30-500 mm/s.
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. Fixed TPU bumpers at each end absorb end-of-stroke impact only; they do not hold or brake a load, so use a rod lock or pilot check for suspended loads. FA/FB flanges, LB foot and FTC brackets plus I/Y knuckles fit the standard face. Sensing requires the optional -S magnet code, which enables CMSE / DMSE switches; this non-S version carries no magnet.
