Airtac ACED Double-acting Compact Cylinder ACED125X30B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X30B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 30mm 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 ACED125X30B
A double acting compact cylinder built to ISO 21287, the ACED125X30B pushes a 25 mm hard-chrome rod out of BOTH covers, so thrust is identical on the extend and retract strokes. At the bore 125 class it delivers 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction, with a fixed TPU bumper at each end absorbing the stop. The male rod thread (B code) bolts straight to your tooling.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 30 mm stroke press or clamp has to live inside a guarded frame. Practical sizing: keep real work near 3530 N at 0.5 MPa, which is roughly a 360 kg vertical equivalent, or about 300 kg with a 2:1 margin. The through-rod also resists rotation and side load, and the rear rod can carry a sensor flag. FA/FB flanges, LB feet and FTC brackets plus I/Y knuckles mount on the standard face. No magnet is fitted; order the -S code if you need 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 ACED125X30B Is Used
Heavy stamping and forming press
A 30 mm stroke is ideal for coining, embossing or crimping aluminium terminal lugs in a compact press head; the 5890.5 N through-rod keeps the tool square under off-centre loads.
Pallet strapper tensioner
In warehouse strapping machines the symmetric double rod drives a tension blade and returns with equal 8246.7 N at 0.7 MPa, so strap pull is repeatable in both directions.
Die clamp on a machining centre fixture
Clamping turbine-blade fixtures on a 5-axis line: the male rod thread takes a clamp arm directly, and the short body fits inside the fixture base where a full-length profile cylinder cannot.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X30B the Right Cylinder?
At 5890.5 N per direction this is the top of the ACED range; if your load needs under 3769.9 N at 0.5 MPa, the ACED100 saves space and air, while there is no larger bore to step up to. The 30 mm stroke sits well inside the 300 mm maximum standard stroke for bore 125, so it is a catalogue item, not a made-to-order build. Remember the piston drifts if air is lost - add a rod lock or pilot check valve where a load must stay put. Specify PT ports (default) or G, and add -S only when CMSE / DMSE position sensing is required.
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 ACED125X30B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal in extend and retract: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, peaking at about 1201.3 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s and -20 to +70 C.
The B code gives a male thread on the 25 mm rod at both ends, ready for tooling or knuckles; ports are 1/4" PT (or G on request). Position sensing needs the optional -S magnet ordered with the cylinder - without it no magnet is fitted and CMSE / DMSE switches cannot work. The fixed TPU bumpers at each end only soften the stops; they never hold a load, so use a rod lock or pilot check where drift matters.
