Airtac ACED Double-acting Compact Cylinder ACED125X150S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X150S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 150mm 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 ACED125X150S
A double acting compact cylinder built to ISO 21287, the ACED125X150S pushes a 25 mm rod out of BOTH covers, so thrust is identical on every stroke: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa. The 150 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, and the through-rod gives a symmetric mount that resists rotation and side load.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is how a 125 mm bore fits into heavy presses and gantries where a full-length body will not. Because the piston drifts when air is lost, add a rod lock or pilot check if the load must stay put. As a rule of thumb, plan on roughly 3534 N of real work at 0.5 MPa - enough to lift about 180 kg vertically with a 2:1 margin. The -S code on this model means the magnet is fitted, so CMSE / DMSE switches can be clipped to the body slots right away.

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 ACED125X150S Is Used
Heavy press and forming station
The 5890.5 N rod-side thrust at 0.5 MPa (8246.7 N at 0.7 MPa) suits crimping, staking and light forming on aluminium extrusions, with the second rod keeping the tool plate square under off-center load.
Gantry lift-and-lower module
A symmetric through-rod on both covers lets the same 25 mm rod lift and lower a die cart or fixture, and the 150 mm stroke covers tray-height changes; expect about 180 kg vertical lift with a 2:1 margin.
Position-verified clamp on a machining line
With the -S magnet already fitted, CMSE / DMSE switches confirm full clamp and full retract on a CNC fixture clamping steel blocks, running 30-500 mm/s under PLC control.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X150S the Right Cylinder?
At 5890.5 N per direction, this is the top of the ACED range; step down to the ACED100 (3769.9 N at 0.5 MPa) if the load is lighter, or stay here for presses above 500 kg equivalent. Remember it will not hold position without air - pair it with a rod lock for held loads. Mounting brackets (FA/FB flange, LB foot, FTC) plus I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet means CMSE / DMSE position switches work without reordering.
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 ACED125X150S FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal push and pull, 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" port matches the 125 mm bore.
It is an ISO 21287 compact cylinder: a hard-anodized aluminium body with threaded covers and a fixed TPU bumper at each end, about 50% shorter in mounting length than an ISO 15552 profile cylinder. The S in the model code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches mount in the body slots. Note the bumper only decelerates at stroke ends - it never locks or holds a load, so use a rod lock or pilot check where a held position matters.
