About the Airtac ACED Double-acting Compact Cylinder ACED125X90
The ACED125X90 is a double acting, double-rod compact cylinder built to ISO 21287: a 125 mm bore with a 25 mm hard-chrome-plated S45C rod exiting BOTH covers, so thrust is identical on the extend and retract strokes - 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa either way. The hard-anodized aluminium body keeps the footprint short, saving about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into heavy press fixtures and gantry frames where a full-length body will not fit.
Because the through-rod resists rotation and side load, the back-end rod can carry a sensor flag or a second tooling plate. In practice, plan on roughly 3534 N of usable work at 0.5 MPa (about 60% of rating), which is a vertical lift of around 300 kg with a 2:1 margin - enough to raise a loaded pallet clamp or close a large gate valve. Air supply is 0.15-1.0 MPa (22-145 psi), speed runs 30-500 mm/s, and fixed TPU bumpers absorb end-of-stroke shock at both covers. Note that with no air applied the piston drifts freely; add a rod lock or pilot check valve if the load must stay put.

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 ACED125X90 Is Used
Pallet clamp actuation
The 5890.5 N symmetric thrust clamps and releases heavy pallets in machining cells, with the 90 mm stroke clearing fixture pins quickly at up to 500 mm/s.
Gantry lift assist
A through-rod on both covers lets one cylinder lift and counter-lift a 300 kg-class die cart platform with equal force, keeping the mount symmetric and rotation-free.
Large gate valve cycling
Water-treatment gate valves need high force in both travel directions; the rod-side area delivers 8246.7 N at 0.7 MPa opening and closing alike.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X90 the Right Cylinder?
At 125 mm bore this is the top of the ACED range: 5890.5 N at 0.5 MPa both directions. If your load needs under 3769.9 N, the ACED100X90 gives the same 90 mm stroke in a smaller body; if you need more than 8246.7 N at 0.7 MPa, step up to a larger frame or parallel cylinders. The 90 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, so it ships as a standard part. The female M16x2.0 rod thread suits standard rod knuckles (I and Y types), and FA/FB flanges or LB feet bolt straight to the ISO 21287 face. This version has no magnet - order the -S code if you want CMSE / DMSE switch detection.
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 ACED125X90 FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal either way: 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 depends only on the 125 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium barrel and fixed TPU bumpers at both ends to soften stroke completion. Sensors are not included on this model: the magnet is the optional -S ordering code, so specify ACED125X90S if you want CMSE or DMSE switches to detect piston position.
