Airtac ACE Compact Cylinder ACE25X35
The AirTAC Airtac ACE Compact Cylinder ACE25X35 is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 35mm 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 ACE25X35
This AirTAC ACE25X35 is a double acting ISO 21287 compact cylinder with a 25 mm bore and 35 mm stroke, delivering 245.4 N of push force at 0.5 MPa. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guard enclosures where a full-length cylinder would not.
For real-world sizing, plan on about 147 N of usable work at 0.5 MPa, which lifts roughly 15 kg vertically with a 2:1 safety margin. The fixed TPU bumper at each end absorbs impact, and the M5x0.8 port suits small-bore air circuits. This model has no magnet, so order the optional -S code if you need CMSE or DMSE sensor feedback.

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 ACE25X35 Is Used
Jig Clamping
Mount this ACE25X35 on a drill jig to clamp small aluminium brackets during hole drilling. The 245.4 N push holds parts firmly while the compact body keeps the fixture footprint minimal.
Label Applicator
Use in a carton labeling station to press labels onto flat boxes. The 35 mm stroke matches the label length, and the fixed bumper prevents jarring at the end of each cycle.
Small Part Stop
Position as a stop gate on a light conveyor diverting plastic caps. The 206.2 N pull retracts the rod quickly, and the short body fits under the conveyor frame without protruding.
Is the Airtac ACE Compact Cylinder ACE25X35 the Right Cylinder?
At 25 mm bore, this cylinder suits light assembly and clamping tasks. If you need more force, step up to the 32 mm bore which pushes 402.1 N at 0.5 MPa; for lighter work, the 20 mm bore pushes 157.1 N. Since this is a plain double acting cylinder, it will not hold its position if air pressure is lost - use a rod lock or pilot check valve for load holding. The M5x0.8 port and female M6x1.0 rod thread are standard, and you can add FA/FB flange, LB foot, or CA/CB clevis mounts.
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 ACE25X35 FAQ
At 0.5 MPa, push is 245.4 N and pull is 206.2 N. At 0.7 MPa, push rises to 343.6 N and pull to 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), with proof pressure at 1.5 MPa (215 psi).
The ACE25X35 body is about 50% shorter than an ISO 15552 profile cylinder of the same stroke, so it fits inside machine guards and between frame members. It uses a fixed TPU bumper at both ends to absorb impact, and you can order the optional -S magnet to enable CMSE or DMSE switches for position sensing.
