Airtac ACE Compact Cylinder ACE25X75
The AirTAC Airtac ACE Compact Cylinder ACE25X75 is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 75mm stroke, M5×0.8 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 ACE Compact Cylinder ACE25X75
This AirTAC ACE25X75 is a double acting ISO 21287 compact cylinder, pushing with 245.4 N and pulling with 206.2 N at 0.5 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames where a full-length unit will not. The hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous cycling.
At 0.5 MPa, plan for about 147 N of real work as a safe rule of thumb, which translates to lifting roughly 15 kg vertically with a 2:1 margin. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the M5x0.8 port suits small-bore air circuits. This model has no magnet, so CMSE or DMSE sensors cannot be mounted unless you order the optional -S code.

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 ACE25X75 Is Used
Jig Clamping
Use the ACE25X75 to clamp small parts in a CNC fixture; its 245.4 N push holds components firmly during drilling or milling, and the compact body fits under the workholding table.
Sorting Gate
Actuate a diverter gate on a light conveyor line with this cylinder, pushing 245.4 N to redirect packages. The 75 mm stroke moves the gate fully across the lane, and the short body mounts beside the frame without protruding.
Test Probe
Drive a spring-loaded test probe into an electronic assembly for continuity checks. The 206.2 N pull retracts the probe reliably, and the fixed TPU bumper prevents shock to sensitive contacts at the end of stroke.
Is the Airtac ACE Compact Cylinder ACE25X75 the Right Cylinder?
For a lighter push, the ACE20X75 offers 157.1 N at 0.5 MPa, while stepping up to the ACE32X75 gives 402.1 N for heavier loads. The 75 mm stroke suits short transfer slides and clamping actions; if you need position holding when air is lost, add a pilot check valve or rod lock, as the bumper does not lock the rod. Choose the -S option for the built-in magnet if you plan to use CMSE or DMSE switches, and pick FA/FB flange, LB foot, or CA/CB clevis mounts to match your fixture.
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 ACE25X75 FAQ
At 0.5 MPa, the push force is 245.4 N and the pull force 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. These numbers are based on the 25 mm bore and 10 mm rod.
It is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight machines. The fixed TPU bumper absorbs end-of-stroke impact, but it does not adjust or lock. Sensors are not standard; you must order the -S code to get the magnet, which then allows CMSE or DMSE switches to be mounted.
