Airtac ACE Compact Cylinder ACE25X80B
The AirTAC Airtac ACE Compact Cylinder ACE25X80B is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 80mm 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 ACE25X80B
This compact double-acting cylinder delivers a 245.4 N push and 206.2 N pull at 0.5 MPa, making it a solid choice for light assembly tasks. Its ISO 21287 short body takes up about half the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a longer unit will not.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling. With a male rod thread (B code) and M5x0.8 port, it connects directly to standard fixtures. For a 2:1 safety margin on vertical moves, plan to lift about 12.5 kg with this unit at 0.5 MPa, not the full theoretical rating.

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 ACE25X80B Is Used
Fixture Clamping
Use the 245.4 N push at 0.5 MPa to clamp small plastic housings in a drill fixture, with the compact body fitting under a machine guard.
Label Applicator
Drive a label tamp head on a carton sealing line; the 80 mm stroke and 206.2 N pull retract quickly for cycle rates up to 500 mm/s.
Parts Ejector
Eject machined bushings from a vice on a benchtop press, using the 343.6 N push at 0.7 MPa to clear stuck parts reliably.
Is the Airtac ACE Compact Cylinder ACE25X80B the Right Cylinder?
For lighter work, the 20 mm bore ACE20X80 offers 157.1 N push at 0.5 MPa, while stepping up to the 32 mm bore ACE32X80 gives 402.1 N push for heavier jigs. This 25 mm bore unit suits medium-duty pushing and clamping where space is limited. Since this model has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted; order the -S version if you need position sensing. The male rod thread simplifies coupling to custom tooling.
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 ACE25X80B 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).
No, this model has no magnet because the -S option was not ordered. Without the optional -S magnet, CMSE or DMSE reed or solid-state switches cannot be mounted. The fixed TPU bumper at both ends only absorbs end-of-stroke impact; it does not hold a load in position if air pressure is lost.
