Airtac ACE Compact Cylinder ACE25X150S
The AirTAC Airtac ACE Compact Cylinder ACE25X150S is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 150mm 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 ACE25X150S
This AirTAC ACE25X150S is a double acting compact cylinder that extends and retracts its rod with air pressure. Its 25 mm bore delivers 245.4 N of push force at 0.5 MPa, making it a solid choice for light assembly tasks. The short ISO 21287 body takes up about 50% less mounting length than an ISO 15552 profile cylinder, so it fits neatly inside tight machine guards and compact jigs.
With the optional -S magnet fitted, this unit works with CMSE or DMSE reed and solid-state switches for reliable end-of-stroke sensing. As a practical guide, plan for a usable load of about 147 N at 0.5 MPa, which means it can lift roughly 15 kg vertically with a 2:1 safety margin. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in high-cycle applications.

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 ACE25X150S Is Used
PCB Alignment
Use the 150 mm stroke to push a locating pin into a PCB drilling fixture, with the 245.4 N force holding thin boards flat during the operation.
Carton Tucking
Mount this cylinder on a carton former to tuck side flaps before sealing. The 206.2 N retract force pulls the tucker arm back quickly for the next cycle.
Sorting Gate
Actuate a diverter gate on a small parts conveyor. The 150 mm stroke moves the gate fully across a 100 mm chute, and the compact body fits under the belt frame.
Is the Airtac ACE Compact Cylinder ACE25X150S the Right Cylinder?
When sizing, compare this 25 mm bore unit to a smaller 20 mm bore ACE that pushes 157.1 N, or step up to a 32 mm bore ACE that pushes 402.1 N at the same 0.5 MPa pressure. The 150 mm stroke matches the maximum standard stroke for this bore, so you get full travel without a custom order. Since this model carries the -S magnet, pair it with a CMSE or DMSE sensor for position feedback; without the -S code, no magnet is present. For mounting, choose from FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets that bolt directly to the ISO 21287 face.
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 ACE25X150S 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 increases to 343.6 N and pull to 288.6 N. The theoretical maximum force at 1.0 MPa is 50.1 kgf. These figures apply to the 25 mm bore with a 10 mm rod.
The ACE25X150S uses a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, so it saves valuable space in tight enclosures. It has a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors to detect the piston position. The M5x0.8 port accepts standard fittings for quick installation.
