About the Airtac ACED Double-acting Compact Cylinder ACED125X80S
The ACED125X80S is a double acting, double-rod compact cylinder built to ISO 21287: a 125 mm bore with an 80 mm stroke, a 25 mm piston rod exiting both covers, and a 1/4" PT port. Because both strokes work on the rod-side area, output is identical in each direction - 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, peaking at 1201.3 kgf at 1.0 MPa. The hard-anodized aluminium body carries the S code, so the magnet is fitted and CMSE / DMSE reed or solid-state switches can be clipped straight onto the body slots.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 125 mm bore has to fit inside a press frame or heavy gantry. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag or a second tool. A fixed TPU bumper at each end absorbs end-of-stroke energy. As a rule of thumb, plan on roughly 3534 N - about 360 kg of vertical lift - for real work at 0.5 MPa instead of the full rating.

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 ACED125X80S Is Used
Heavy press fixture clamping
The 5890.5 N rod-side force at 0.5 MPa clamps steel weldments in a machining fixture, and the 80 mm stroke clears part loading without a long body.
Pallet lift-and-lower station
Equal force both ways suits a vertical push-pull actuator; the through-rod resists rotation so the pallet plate stays square through the 80 mm travel.
Baler ram positioning
With the fitted -S magnet and a DMSE switch, the ram reports end positions to the PLC, and the rear rod carries a second flag for mid-stroke confirmation.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X80S the Right Cylinder?
At 125 mm bore this is the top of the ACED range; if 5890.5 N at 0.5 MPa is more than the job needs, the ACED100X80S delivers 3769.9 N in the same compact format, while there is no larger bore to step up to. Stroke 80 mm sits well inside the 300 mm maximum standard stroke for this bore, so it ships as a standard build. Mounting is via FA/FB flange, LB foot or FTC brackets on the ISO 21287 face, with I and Y rod knuckles for the through-rod. Note that like any plain double-rod cylinder it will drift if air is lost - add a rod lock or pilot check where a load must be held.
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 ACED125X80S 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 pressure 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" PT port matches the 125 mm bore.
The S code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches mount directly in the body slots for position feedback. The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, uses a hard-anodized aluminium barrel with an S45C hard-chrome 25 mm rod, and has a fixed TPU bumper at both ends. FA/FB flange, LB foot and FTC brackets bolt straight to the standard face.
