Airtac ACE Compact Cylinder ACE25X50
The AirTAC Airtac ACE Compact Cylinder ACE25X50 is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 50mm 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 ACE25X50
This AirTAC ACE25X50 is a double acting compact cylinder built to ISO 21287, with a 25 mm bore and a 50 mm stroke. It delivers 245.4 N of push force at 0.5 MPa, which is enough to lift about 15 kg vertically with a 2:1 safety margin, or about 25 kg if you use the full theoretical rating at 1.0 MPa.
The short body saves roughly 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits neatly into tight jigs and guarded machine zones. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear, while the fixed TPU bumper at each end softens the stop. This version has no magnet, so it cannot accept CMSE or DMSE sensors unless you order the optional -S magnet code.

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 ACE25X50 Is Used
Fixture Clamping
Use the ACE25X50 to clamp small parts in a CNC vise or a dedicated assembly fixture, where its 245.4 N push at 0.5 MPa holds components securely without taking up much space.
Label Applicator
Drive a label applicator head in a packaging line with a 50 mm stroke, using the compact body to fit between guide rails and the 206.2 N pull force to retract quickly after each cycle.
Guard Door Interlock
Activate a small guard-door latch on a semi-automatic machine, where the 25 mm bore provides enough force to move a light interlock mechanism and the short stroke matches the door travel.
Is the Airtac ACE Compact Cylinder ACE25X50 the Right Cylinder?
For a lighter duty, the ACE20X50 offers 157.1 N push at 0.5 MPa, while stepping up to the ACE32X50 gives you 402.1 N push at the same pressure. Choose the ACE25X50 when you need a balance of compact size and moderate force for a 50 mm stroke application. Since this model has no magnet, order the -S suffix if you plan to use CMSE or DMSE reed switches for position sensing. The M5x0.8 port suits small-bore plumbing, and the female M6x1.0 rod thread accepts standard clevis or rod-end accessories.
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 ACE25X50 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 at 1.0 MPa is 50.1 kgf. The operating pressure range is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
Yes, it is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder of the same bore. It has a fixed TPU bumper at both ends, not an adjustable cushion. This version has no magnet, so you cannot mount CMSE or DMSE switches unless you order the optional -S magnet code. The body is hard-anodized aluminium with a hard-chrome plated S45C steel rod.
