Airtac ACE Compact Cylinder ACE25X10
The AirTAC Airtac ACE Compact Cylinder ACE25X10 is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 10mm 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 ACE25X10
The ACE25X10 is a double acting ISO 21287 compact cylinder that uses air to extend and retract its 10 mm stroke rod. Its 25 mm bore delivers 245.4 N of push force at 0.5 MPa, making it a solid choice for light automation tasks. The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where space is at a premium.
For a real-world load, plan on about 15 kg of safe vertical lift at 0.5 MPa (245.4 N divided by 9.81, then halved for a 2:1 safety margin). This model has no magnet fitted, so it cannot accept CMSE or DMSE sensors unless you order the optional -S code. The fixed TPU bumper at each end absorbs impact, and the M5x0.8 port suits small-bore plumbing.

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 ACE25X10 Is Used
Jig Clamping
Use the ACE25X10 to clamp small parts in a CNC fixture, applying 245.4 N of force to hold a bracket steady during drilling or milling operations.
Light Box Taping
In a packaging line, this cylinder can push a tape head down onto a box flap with a 10 mm stroke, providing a quick and repeatable action for sealing cartons.
Small Part Ejection
Mount the ACE25X10 to eject a finished plastic part from an injection mold or die, using its 206.2 N pull force to retract a pin and clear the cavity.
Is the Airtac ACE Compact Cylinder ACE25X10 the Right Cylinder?
When sizing, compare the ACE25X10 against the smaller ACE20X10 (157.1 N push) if your load is under 10 kg, or step up to the ACE32X10 (402.1 N push) for more headroom. This 25 mm bore is a balanced middle ground for grippers, light presses, and clamping fixtures. Since there is no magnet, you cannot add position sensors without ordering the -S version, so plan for that if you need end-of-stroke detection. The female M6x1.0 rod thread and M5x0.8 port are standard for this bore, and the compact body mounts easily with FA/FB flanges or LB foot brackets.
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 ACE25X10 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. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the proof pressure is 1.5 MPa (215 psi).
Yes, it is an ISO 21287 compact cylinder with a body about 50% shorter than an ISO 15552 profile cylinder, which helps in tight spaces. However, this model has no magnet, so CMSE or DMSE sensors cannot be mounted unless you order the -S code for the optional magnet. The fixed TPU bumper at both ends absorbs end-of-stroke impact, but it does not lock or hold a load.
