Airtac ACE Compact Cylinder ACE25X25B
The AirTAC Airtac ACE Compact Cylinder ACE25X25B is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 25mm 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 ACE25X25B
This AirTAC ACE25X25B is a double acting ISO 21287 compact cylinder that uses air to both extend and retract its 10 mm rod. The 25 mm bore delivers 245.4 N of push force at 0.5 MPa, which is enough to handle light assembly tasks while the short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder.
With a male rod thread (B code) and no magnet fitted, this unit is ready for direct coupling to a linkage or fixture. For a safe working load, plan for about 147 N of real work at 0.5 MPa, which translates to lifting roughly 15 kg vertically with a 2:1 safety margin. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the hard-anodized aluminium body with S45C hard-chrome rod ensures long service life.

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 ACE25X25B Is Used
Light Assembly Jig
Use in a benchtop press for inserting small pins into plastic housings, where 245.4 N push at 0.5 MPa provides controlled force and the short body fits under a guard.
Tight-Space Clamping
Mount on a machine guard or gantry to clamp thin sheet metal during drilling, taking advantage of the 50% shorter body than an ISO 15552 profile cylinder.
Parts Transfer Slide
Drive a small slide that shuttles components between two conveyor lanes, with the 25 mm stroke and 206.2 N pull force moving parts reliably at speeds up to 500 mm/s.
Is the Airtac ACE Compact Cylinder ACE25X25B the Right Cylinder?
When sizing this ACE25X25B, compare it with the smaller ACE20X25 which offers 157.1 N push at 0.5 MPa, or the larger ACE32X25 which provides 402.1 N push at 0.5 MPa. For this 25 mm bore, the M5x0.8 port suits small-bore applications, and the 25 mm stroke fits compact jigs and fixtures. Since there is no magnet, it cannot be used with CMSE or DMSE switches; order the -S version if you need position sensing. The male rod thread simplifies mounting to clevises or rod knuckles, and the ISO 21287 face accepts FA/FB flange, LB foot, and CA/CB clevis brackets.
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 ACE25X25B 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 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 of 1.5 MPa (215 psi).
It follows ISO 21287, giving a body about 50% shorter than an ISO 15552 profile cylinder, ideal for tight fixtures. The fixed TPU bumper at both ends absorbs impact, but it does not lock or hold a load; for position holding, use a rod lock or pilot check valve. The optional -S magnet enables CMSE or DMSE switches for sensing.
