Airtac ACE Compact Cylinder ACE25X90S
The AirTAC Airtac ACE Compact Cylinder ACE25X90S is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 90mm 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 ACE25X90S
This AirTAC ACE25X90S is a double acting compact cylinder that uses air to both extend and retract its 10 mm rod. Its 25 mm bore delivers 245.4 N of push force at 0.5 MPa, enough to handle light assembly tasks while the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight machine guards and jigs.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in high-cycle applications. With the optional -S magnet fitted, you can mount CMSE or DMSE reed and solid-state switches for position sensing. For a real-world load, plan on about 15 kg of usable vertical lift (245.4 N divided by 9.81 and halved for a 2:1 safety margin), so it can handle small part pushers or light clamping fixtures.

Where the Airtac ACE Compact Cylinder ACE25X90S Is Used
Light Assembly Jig
Use the ACE25X90S to actuate a pin or clamp in a small assembly fixture for electronics enclosures, where its compact body fits under a workbench guard and the 90 mm stroke provides enough travel to engage a locating pin.
Carton Tuck Helper
In a packaging line, this cylinder can push a folded carton flap into place before sealing. The 245.4 N push at 0.5 MPa is ample for light cardboard, and the short stroke cycle speed of 30-500 mm/s keeps up with moderate line rates.
Small Part Ejector
Mount the ACE25X90S on a bench press to eject stamped metal washers from a die. Its 90 mm stroke clears the part, and the fixed TPU bumper at both ends absorbs the impact of rapid cycling without damaging the rod.
Is the Airtac ACE Compact Cylinder ACE25X90S the Right Cylinder?
For a lighter load, the ACE20X90S offers 157.1 N push at 0.5 MPa, while stepping up to the ACE32X90S gives you 402.1 N push for heavier work. Since this is a double acting cylinder, it does not hold its position when air pressure is lost or the valve is centered - the rod will drift. Use a rod lock or pilot check valve if you need to hold a load in place. The M5x0.8 port suits small-bore pneumatic circuits, 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 ACE25X90S 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. These are based on a 25 mm bore with a 10 mm rod.
The ACE25X90S body is about 50% shorter than an ISO 15552 profile cylinder of the same stroke, so it fits into machine guards and gantries where a full-length cylinder would not. It uses a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE switch mounting for position feedback.
