About the Airtac ACE Compact Cylinder ACE25X90
This AirTAC ACE25X90 is a double acting compact cylinder built to ISO 21287, with a 25 mm bore and a 90 mm stroke. It delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, so it suits light assembly and clamping tasks. The hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous cycling.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which helps when space is tight inside a guard or jig. At 0.5 MPa, plan for a safe working load of about 147 N (roughly 15 kg) to keep a 2:1 margin. The fixed TPU bumper at both ends absorbs end-of-stroke impact, while the M5x0.8 port keeps plumbing compact.

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 ACE25X90 Is Used
Fixture Clamping
Use in a pneumatic jig to clamp small sheet metal parts during drilling or riveting, where the 245.4 N push force holds the workpiece firmly without marring it.
Carton Tabbing
Drive a tab-folding mechanism on a packaging line, where the 90 mm stroke moves a guide plate to fold flaps on corrugated boxes at speeds up to 500 mm/s.
Light Press Operation
Power a small arbor press for inserting brass bushings into plastic housings, relying on the 206.2 N pull force to retract the ram after each cycle.
Is the Airtac ACE Compact Cylinder ACE25X90 the Right Cylinder?
For a lighter load, the ACE20X90 with 157.1 N push at 0.5 MPa may be enough; for more force, the ACE32X90 provides 402.1 N push at 0.5 MPa. This 25 mm bore model fits between them, offering a balance of force and compact size. Since this unit has no magnet (no -S code), it cannot mount CMSE or DMSE sensors; order the ACE25X90S variant if you need position sensing. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with 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 ACE25X90 FAQ
At 0.5 MPa, push force is 245.4 N and pull force 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), with proof pressure at 1.5 MPa (215 psi).
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits into tight spaces like machine guards or gantries. The fixed TPU bumper absorbs end-of-stroke energy, and the hard-anodized aluminium body resists wear. Note that this version has no magnet, so order the -S code if you need CMSE or DMSE sensors.
