Airtac ACED Double-acting Compact Cylinder ACED125X250
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X250 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 250mm 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 ACED125X250
A double acting compact cylinder built to ISO 21287, the ACED125X250 pushes a 25 mm rod out of BOTH covers, so the 125 mm bore delivers an identical 5890.5 N at 0.5 MPa in each direction - the rod-side area works for both strokes. At 0.7 MPa that rises to 8246.7 N either way, with a peak of 1201.3 kgf at 1.0 MPa. The through-rod resists rotation and side load and gives a symmetric mounting face at each end.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 250 mm stroke must fit inside a press frame or gantry. A fixed TPU bumper at each end absorbs end-of-stroke shock, the hard-anodized aluminium body carries a hard-chrome S45C rod, and the through-rod at the rear can carry a sensor flag. As a rule of thumb, plan on about 3534 N (roughly 360 kg) of real work at 0.5 MPa, and expect it to lift about 300 kg vertically with a 2:1 margin. 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 ACED125X250 Is Used
Heavy press and forming fixtures
The symmetric 5890.5 N output in both directions suits stamping and forming jigs where the return stroke must clamp as hard as the push, all inside a body about 50% shorter than an ISO 15552 profile cylinder.
Pallet lift-and-lower stations
With a usable vertical lift of about 300 kg at a 2:1 margin, the double rod guides the load on both sides, and the rear rod can carry a flag for a CMSE or DMSE switch when the -S magnet is ordered.
Heavy gate and door actuation
The through-rod resists the rotation and side load of sliding or swinging gates in material handling, with the fixed TPU bumper softening each end of the 250 mm travel.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X250 the Right Cylinder?
At the top of the range: the next size down, ACED100, gives 3769.9 N at 0.5 MPa if your load is lighter, while this 125 mm bore adds 2120 N more for heavy clamping or lifting. Stroke 250 mm sits inside the 300 mm maximum standard stroke for this bore, so no made-to-order build is needed. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face. The female M16x2.0 rod thread suits standard rod attachments. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. Sensors need the optional -S magnet code, which enables CMSE / DMSE switches.
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 ACED125X250 FAQ
Yes - this is a double-rod cylinder, so a rod exits both covers and both strokes use the rod-side area. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, identical in each direction, with a maximum of 1201.3 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 1/4" port depends only on the 125 mm bore.
The ISO 21287 compact body is hard-anodized aluminium with an S45C hard-chrome rod, and it saves about 50% of the mounting length of an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke energy but does not hold or brake a load - for a held load add a rod lock or pilot check. FA/FB flange, LB foot and FTC brackets plus I/Y knuckles mount on the standard face. Position sensing requires the optional -S magnet code, which allows CMSE / DMSE switches; without -S no magnet is fitted.
