Airtac ACED Double-acting Compact Cylinder ACED125X80
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X80 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 80mm 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 ACED125X80
A double acting compact cylinder built to ISO 21287, the ACED125X80 pushes a 125 mm piston through an 80 mm stroke with a 25 mm rod exiting BOTH covers. Because each side sees the rod-side area, output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction - there is no weaker pull stroke. The hard-anodized aluminium body carries a fixed TPU bumper at each end, and the S45C hard-chrome plated rod shrugs off wear on heavy clamping duty.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 125 mm bore fits presses and gantries where a full-length body cannot. As a working rule, plan on roughly 3534 N (about 360 kgf) of usable force at 0.5 MPa, which lifts about 300 kg vertically with a 2:1 margin. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag. Note: this code has no magnet, so CMSE / DMSE switches need the optional -S version.

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 ACED125X80 Is Used
Heavy stamping and forming clamps
The 5890.5 N double-sided thrust at 0.5 MPa clamps steel sheet in stamping dies, and the 80 mm stroke clears part loading quickly.
Pallet and fixture lift-assist arms
With about 300 kg vertical lift capacity at a 2:1 margin, the through-rod raises and lowers heavy fixture plates with equal force up and down.
Press gantry ejector stations
The short ISO 21287 body slots under low press gantries where an ISO 15552 profile cylinder would not fit, ejecting castings at up to 500 mm/s.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X80 the Right Cylinder?
At 5890.5 N per direction, the 125 mm bore sits at the top of the ACED range - step down to the 100 mm bore (3769.9 N at 0.5 MPa) for lighter clamps or up to nothing larger in this series. Both strokes deliver identical force, so sizing is the same whichever end does the work. Remember the piston drifts if air is lost; add a rod lock or pilot check valve for a held load. FA/FB flange, LB foot and FTC brackets bolt to the ISO 21287 face, with I and Y rod knuckles for the through-rod ends. Order the -S code if you need position sensing.
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 ACED125X80 FAQ
Yes - the double-rod design puts a 25 mm rod on both covers, so both strokes use 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 peak 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, air filtered to 40 um, -20 to +70 C.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end to soften stroke ends. Sensing is not fitted on this code: order the optional -S magnet version to run CMSE or DMSE switches on the body slots. Mounting brackets (FA/FB flange, LB foot, FTC) and I/Y rod knuckles attach to the standard ISO 21287 face.
