Airtac ACED Double-acting Compact Cylinder ACED125X5
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X5 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 5mm 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 ACED125X5
A double acting compact cylinder built to ISO 21287, the ACED125X5 pushes a 125 mm bore through a short 5 mm stroke with a rod leaving both covers. Because each side sees the rod-side area, output is a matched 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 its rear end can carry a sensor flag on clamping fixtures.
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, with a fixed TPU bumper at each end. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy presses and weld fixtures where a full-length body cannot. As a rule of thumb, plan on roughly 360 kg of usable vertical load, and the rod will lift about 300 kg vertically with a 2:1 margin.

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 ACED125X5 Is Used
Stamping die proof clamps
The 5890.5 N symmetric thrust clamps automotive stamping dies on a press bed, and the 5 mm stroke is enough to seat and release a clamp block without long retraction delay.
Weld fixture part ejectors
A through-rod on both covers lets a rear rod kick a sensor flag while the front rod ejects a welded bracket from its locating pins at up to 500 mm/s.
Press-fit assist heads
Short-travel assist for pressing bushings into housings: the 125 mm bore delivers 8246.7 N at 0.7 MPa from both rod ends, with the TPU bumper absorbing the end-of-stroke shock.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X5 the Right Cylinder?
At 5890.5 N per side at 0.5 MPa, this 125 mm bore sits at the top of the ACED range; step down to the 100 mm bore (3769.9 N) for lighter clamps or stay here for heavy stamping and forming dies. The 5 mm stroke is well inside the 300 mm maximum standard stroke for this bore. Ports are 1/4" PT and the rod ends in a female M16x2.0 thread; FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Note that with no -S magnet ordered there is no magnet, so no CMSE or DMSE switch can be fitted, and the cylinder will drift if air is lost - add a rod lock or pilot check for a held load.
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 ACED125X5 FAQ
Force is equal both ways because a rod exits each cover and both strokes use the rod-side area: 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.
It is an ISO 21287 short-body unit, about 50% shorter in mounting length than an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and a fixed TPU bumper at each end. Position sensing needs the optional -S magnet code, which allows CMSE or DMSE switches; without -S no magnet is fitted. Mounting brackets (FA/FB flange, LB foot, FTC) and I/Y rod knuckles bolt to the standard ISO 21287 face.
