About the Airtac ACE Compact Cylinder ACE25X15S
This AirTAC ACE25X15S is a double acting ISO 21287 compact cylinder with a 25 mm bore and 15 mm stroke, delivering 245.4 N of push force at 0.5 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight automation frames where space is at a premium.
With the optional -S magnet already fitted, this unit works with CMSE or DMSE reed and solid-state switches for reliable position sensing. For a 2:1 safety margin, plan to lift about 12.5 kg vertically at 0.5 MPa, and the hard-anodized aluminium body with S45C chrome-plated rod ensures long service in repetitive cycles.

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 ACE25X15S Is Used
Fixture Clamping
Use the 245.4 N push to clamp small parts in a CNC fixture, where the 15 mm stroke and compact body fit under a workholding vise.
Short Transfer
In a packaging line, this cylinder can push a 12.5 kg carton off a conveyor onto a side chute, with the magnet confirming the extended position.
Guard Door Latch
Mount on a machine guard to retract a latch pin, using the 206.2 N pull force at 0.5 MPa to release the door in a compact enclosure.
Is the Airtac ACE Compact Cylinder ACE25X15S the Right Cylinder?
When sizing, compare this 25 mm bore against a smaller 20 mm bore (157.1 N push) if your load is light, or step up to a 32 mm bore (402.1 N push) for extra margin. This 15 mm stroke suits short transfer or clamping tasks, and the M5x0.8 port simplifies piping in compact layouts.
Since the magnet is fitted, order CMSE or DMSE switches to confirm position. For mounting, choose FA/FB flange, LB foot, or CA/CB clevis brackets to match your fixture. Remember, this cylinder does not hold position when air is removed; use a rod lock or pilot check valve for load holding.
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 ACE25X15S FAQ
At 0.5 MPa, push is 245.4 N and pull 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. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed range is 30-500 mm/s.
The ACE25X15S body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight jigs and guards. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet enables CMSE or DMSE sensors. Note that it does not hold loads without air pressure.
