About the Airtac ACE Compact Cylinder ACE25X75S
This AirTAC ACE25X75S is a double acting compact cylinder built to ISO 21287, with a 25 mm bore and a 75 mm stroke. Its hard-anodized aluminium body and S45C hard-chrome plated rod resist wear, while a fixed TPU bumper at each end absorbs impact. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length cylinder will not.
With a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa, this unit suits light assembly tasks. As a practical rule, plan for about 15 kg of safe vertical lift at 0.5 MPa (245.4 N divided by 9.81, then halved for a 2:1 margin). The optional -S magnet is fitted on this model, so you can mount CMSE or DMSE reed or solid-state switches for position sensing.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACE Compact Cylinder ACE25X75S Is Used
Jig Clamping
Use in a drilling jig to clamp small aluminium parts with 245.4 N push force, fitting into confined spaces around the spindle.
Label Applicator
Drive a label tamp head on a packaging line, where the 75 mm stroke cycles at speeds up to 500 mm/s for quick application.
Guard Door Interlock
Actuate a safety guard latch on a light machine, with the compact body fitting behind a hinged cover and the optional magnet signaling door position.
Is the Airtac ACE Compact Cylinder ACE25X75S the Right Cylinder?
For a lighter duty, consider the ACE20X75 with 157.1 N push at 0.5 MPa, or step up to the ACE32X75 with 402.1 N push for heavier clamping. The M5x0.8 port is standard for this 25 mm bore, and the female rod thread is M6x1.0. This cylinder does not hold its position when air pressure is lost, so add a rod lock or pilot check valve if you must hold a load. The FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets bolt directly to the ISO 21287 face, making installation into standard fixtures straightforward.
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 ACE Compact Cylinder ACE25X75S FAQ
At 0.5 MPa, push is 245.4 N and pull is 206.2 N. At 0.7 MPa, push is 343.6 N and pull is 288.6 N. The theoretical maximum force is 50.1 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits in tight jigs and guards. The fixed TPU bumper absorbs end-of-stroke impact, but it does not lock or hold a load. The optional -S magnet on this model allows CMSE or DMSE switches for position sensing.
