Airtac ACE Compact Cylinder ACE25X25
The AirTAC Airtac ACE Compact Cylinder ACE25X25 is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 25mm 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 ACE25X25
This AirTAC ACE25X25 is a double acting compact cylinder built to ISO 21287, with a 25 mm bore and a 25 mm stroke. It delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, so it suits light assembly and clamping tasks where space is tight. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling.
Because the body is about 50% shorter than an ISO 15552 profile cylinder, it fits into compact jigs and guarding where a full-length unit will not. At 0.5 MPa, a practical working load is about 15 kg (roughly 60% of the rated push), so it can lift a 15 kg part vertically with a 2:1 safety margin. The fixed TPU bumper at each end absorbs impact, and the M5x0.8 port keeps installation simple.

Where the Airtac ACE Compact Cylinder ACE25X25 Is Used
Fixture Clamping
Use in a CNC fixture to clamp small aluminium parts with 245.4 N force, holding them securely during drilling or milling operations.
Carton Tabbing
Drive a tab-folding mechanism on a packaging line, where the 25 mm stroke and compact body fit between conveyor rails and cycle at up to 500 mm/s.
Guard Door Stop
Actuate a safety guard latch on a small press, using the 206.2 N pull force to retract a pin and the fixed bumper to handle end-of-stroke impact.
Is the Airtac ACE Compact Cylinder ACE25X25 the Right Cylinder?
For a lighter duty, consider the ACE20X25 with 157.1 N push at 0.5 MPa, or step up to the ACE32X25 for 402.1 N push if your load grows. This model has no magnet fitted, so order the -S option if you need CMSE or DMSE sensor feedback. The female M6x1.0 rod thread suits direct coupling, and the compact body mounts easily with FA/FB flange 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 ACE25X25 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 a proof pressure of 1.5 MPa (215 psi).
The ISO 21287 compact design saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, making it ideal for tight spaces. However, this model has no magnet fitted, so CMSE or DMSE switches cannot be used unless you order the optional -S code, which adds the magnet for sensor detection.
