Airtac ACED Double-acting Compact Cylinder ACED125X125
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X125 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 125mm 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 ACED125X125
A double acting compact cylinder built to ISO 21287, the ACED125X125 pushes a 125 mm bore through a 125 mm stroke with a rod leaving BOTH covers, so thrust is identical on every stroke: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa. The hard-anodized aluminium body carries a roller-burnished bore, and the S45C hard-chrome plated 25 mm rod runs at 30-500 mm/s on air filtered to 40 um.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 125 mm bore has to live inside a press frame or a guarded gantry. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the through-rod resists rotation and side load while giving you a rear rod for a sensor flag. As a working rule, plan on roughly 3534 N of real work at 0.5 MPa, which lifts about 300 kg vertically with a 2:1 margin. Ports are 1/4" (PT), the female rod thread is M16x2.0, and 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 (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 ACED125X125 Is Used
Heavy press and forming fixtures
The symmetric 5890.5 N output at 0.5 MPa suits stamping, riveting and marking heads where the compact ISO 21287 body must fit inside a closed press frame with a 125 mm working stroke.
Clamping on large machining centres
With about 3534 N of usable work force at 0.5 MPa, the double rod clamps castings or weldments in fixture nests, and the rear rod can carry a flag for position confirmation.
Pallet and container pushers
Equal force in both directions lets one cylinder push a loaded pallet away and retract it under control at 30-500 mm/s, with the TPU bumpers absorbing the ends of each stroke.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X125 the Right Cylinder?
This is the top of the ACED range: at 0.5 MPa it delivers 5890.5 N in both directions, so step down to the ACED100X125 (3769.9 N) if the load is lighter, or step up in stroke only - bore 125 takes standard strokes to 300 mm. Remember the piston drifts if air is lost; add a rod lock or pilot check where a held load matters. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and order the -S code if CMSE / DMSE position sensing is needed.
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 ACED125X125 FAQ
Yes - it is a double-rod cylinder, so a 25 mm rod exits both covers and every stroke uses the rod-side area. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in EITHER 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), and speed range 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 125 mm bore fits where a full-length profile cylinder will not. Position sensing requires the optional -S magnet at ordering; with that code, CMSE and DMSE switches clamp onto the body slots. Without -S there is no magnet and no sensing. Mounting uses FA/FB flange, LB foot or FTC brackets with I/Y rod knuckles.
