About the Airtac ACED Double-acting Compact Cylinder ACED125X70S
The ACED125X70S is a double acting, double rod compact cylinder built to ISO 21287: a 125 mm bore pushes and pulls with identical 5890.5 N output at 0.5 MPa, because a 25 mm rod exits both hard-anodized aluminium covers and both strokes work on the rod-side area. At 0.7 MPa the same piston delivers 8246.7 N in either direction, with a peak of 1201.3 kgf at 1.0 MPa. 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 tooling plate.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this heavy-thrust size still fits presses, gantries and guarding where a full-length body will not. A fixed TPU bumper at each end absorbs end-of-stroke energy, the S45C hard-chrome rod runs at 30-500 mm/s on air filtered to 40 um, and the fitted -S magnet lets CMSE / DMSE reed or solid-state switches report position. Plan on roughly 3534 N (about 360 kg) of real work at 0.5 MPa, and for vertical lifting count on about 300 kg with a 2:1 margin.

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 ACED125X70S Is Used
Heavy stamping and forming fixtures
The symmetric 5890.5 N push and pull at 0.5 MPa suits a 70 mm stroke press head that must retract a die or eject a formed steel bracket with the same force it clamps with.
Pallet stacker lift columns
A through-rod on both ends of the 125 mm piston gives a symmetric lift column for a pallet transfer cart, raising about 300 kg vertically with a 2:1 margin on the 70 mm travel.
Gantry part-present verification
With the fitted -S magnet, CMSE or DMSE switches on the short ISO 21287 body confirm clamp and unclamp positions inside a machine-tool gantry where a full-length profile cylinder cannot fit.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X70S the Right Cylinder?
At 125 mm bore this is the top of the ACED range: 5890.5 N per direction at 0.5 MPa, roughly eight times the 706 N class of a 40 mm bore and well above the 881.2 N of a 50 mm unit. If your clamp or press needs under about 2000 N, step down to a 63 mm bore (1458.1 N) and save air; if you need more than 8246.7 N at 0.7 MPa, twin cylinders or a larger custom bore is the path. The 70 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, so it ships as a standard build. Remember a plain double rod cylinder drifts when air is lost - add a rod lock or pilot check valve for a held load. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and the PT 1/4" ports take standard fittings.
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 ACED125X70S FAQ
Yes - this 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, identical pushing and pulling, 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, temperature -20 to +70 C on air filtered to 40 um.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 125 mm bore fits tight guarding and gantry frames. The fixed TPU bumpers at both ends absorb end-of-stroke energy without adjustment. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly in the body slots for position feedback. Mounting brackets (FA/FB flange, LB foot, FTC) and I/Y rod knuckles bolt straight to the standard face; the rod end is female M16x2.0 with a 1/4" PT port.
