Airtac ACE Compact Cylinder ACE25X120
The AirTAC Airtac ACE Compact Cylinder ACE25X120 is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 120mm 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 ACE25X120
This AirTAC ACE25X120 is a double acting compact cylinder that uses air to both extend and retract its 10 mm rod. It delivers 245.4 N of push force at 0.5 MPa, which translates to a safe vertical lift of about 15 kg when you apply a 2:1 margin, making it a practical choice for light assembly tasks.
The ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine guards and compact jigs where space is limited. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper at each end absorbs impact energy to protect the cylinder at high cycle rates.

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 ACE25X120 Is Used
Fixture Clamping
Use in a CNC machine fixture to clamp small aluminum parts during drilling, providing 245.4 N of force to hold the workpiece securely.
Label Applicator
Drive a label applicator head in a packaging line, where the 120 mm stroke pushes labels onto boxes with consistent pressure and speed.
Guard Door Interlock
Operate a sliding safety guard on a small press, using the compact body to fit within the guard frame and the TPU bumper to reduce noise on each cycle.
Is the Airtac ACE Compact Cylinder ACE25X120 the Right Cylinder?
For a lighter duty, the ACE20X120 offers 157.1 N push, while stepping up to the ACE32X120 gives you 402.1 N push at the same 0.5 MPa, so you can match the force to your actual load. This model has a 120 mm stroke, which is within the 150 mm maximum standard stroke for the 25 mm bore, so it ships as a standard item.
Since this model has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted. If you need position sensing, order the -S version. The M5x0.8 port is ready for standard fittings, and the female M6x1.0 rod thread accepts a variety of attachments.
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 ACE25X120 FAQ
At 0.5 MPa, push force is 245.4 N and 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.
This model has no magnet because it lacks the -S code. To use CMSE or DMSE switches, you must order the version with the optional -S magnet. The fixed TPU bumper handles end-of-stroke impact, but it does not lock the rod in position.
