Airtac ACED Double-acting Compact Cylinder ACED125X25S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X25S 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 ACED125X25S
A double acting, double-rod compact cylinder built to ISO 21287, the ACED125X25S pushes a 125 mm bore through a short 25 mm stroke with a rod leaving both covers. Because each side sees the rod-side area, output is a symmetric 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction. The through-rod resists rotation and side load, and the free back-end rod is a handy place to carry a sensor flag on press or clamp stations.
The hard-anodized aluminium body with an S45C hard-chrome plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy gantries and guarding where a full-length body will not fit. At 0.5 MPa, plan for roughly 3530 N of real work, and the through-rod will lift about 300 kg vertically - halve that for a 2:1 margin on a vertical axis. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the fitted -S magnet accepts 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 (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 ACED125X25S Is Used
Hot-stake press head
The 25 mm stroke and 5890.5 N at 0.5 MPa suit staking bosses on automotive plastic housings, with the symmetric double-rod force keeping the tool square to the part.
Clamp fixture on a machining line
Roughly 300 kg of vertical-lift equivalent lets this bore clamp heavy castings in CNC fixtures, while the short ISO 21287 body fits inside the fixture base.
Balanced reciprocating slide
A rod on both covers gives a symmetric mount for a steel-plate transfer slide, and the fitted -S magnet drives CMSE switches for end-of-stroke confirmation.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X25S the Right Cylinder?
At 5890.5 N per direction at 0.5 MPa, this bore sits near the top of the ACED range; step down to the 100 mm bore (3769.9 N) for lighter presses or stay here for forming and staking heads. If 25 mm of travel is too short, the same bore runs to a 300 mm standard stroke, and longer travels are made to order. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check for a held load. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the female M16x2.0 rod thread suits standard rod attachments.
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 ACED125X25S FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal both ways: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, with a maximum of 1201.3 kgf at 1.0 MPa. Operating range 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 matches the 125 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot or FTC brackets bolt straight to its face. A fixed TPU bumper at each end absorbs end-of-stroke energy. The S in the model code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted anywhere along the body slots.
