Airtac ACE Compact Cylinder ACE25X110B
The AirTAC Airtac ACE Compact Cylinder ACE25X110B is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 110mm 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 ACE25X110B
This AirTAC ACE25X110B is a double acting ISO 21287 compact cylinder with a 25 mm bore and a 110 mm stroke. It delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, with a theoretical maximum of 50.1 kgf at 1.0 MPa. The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length cylinder will not. The male rod thread (B code) simplifies direct coupling to a load or tooling without a rod-end adapter.
Because the optional -S magnet is not ordered, this unit has no built-in magnet, so CMSE or DMSE proximity switches cannot be fitted without changing the cylinder. The fixed TPU bumper at both ends absorbs end-of-stroke impacts, but it does not lock or hold a load; for vertical lifting, plan for about 15 kg of safe working load at 0.5 MPa (0.6 x 245.4 N divided by 9.81), leaving a 2:1 margin over the theoretical rating. The M5x0.8 port suits small-bore pneumatic circuits, and the 110 mm stroke stays within the 150 mm maximum standard stroke for this bore.

Where the Airtac ACE Compact Cylinder ACE25X110B Is Used
Jig Clamping on a CNC Mill
Clamp a small fixture plate in a CNC milling vise with 245.4 N of push force at 0.5 MPa, using the 110 mm stroke to clear the tool path. The short ISO 21287 body fits under the spindle guard where a longer cylinder would not.
Carton Tabbing on a Packaging Line
Push a cardboard tab into a glue station on a carton erector, cycling at 30-500 mm/s. The 206.2 N pull stroke retracts the tabber quickly, and the M5x0.8 port connects to a small solenoid valve in the control cabinet.
Parts Ejector in an Assembly Press
Eject a stamped metal part from a die after a press stroke, using the 110 mm travel to clear the die face. The fixed TPU bumper absorbs the return impact, and the male rod thread mounts a plastic pusher head without extra hardware.
Is the Airtac ACE Compact Cylinder ACE25X110B the Right Cylinder?
For a lighter push, the ACE20X110 offers 157.1 N at 0.5 MPa, while the ACE32X110 steps up to 402.1 N at the same pressure, so you can match the force to the actual load. Since this cylinder is double acting, it extends and retracts with air on both strokes, but it will drift if air pressure is lost or the valve is centered; add a rod lock or pilot check valve if the load must stay put. The male rod thread (B) makes it easy to attach a clevis or rod eye, and the ISO 21287 face accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC mounting brackets. Because the magnet is optional and not fitted here, order the -S version if you need CMSE or DMSE sensor feedback.
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 ACE25X110B 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. The operating pressure range is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
Yes, the ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in confined jigs and guards. However, this model has no magnet because the -S option was not ordered, so CMSE or DMSE switches cannot be mounted. If you need position sensing, order the ACE25X110BS version with the optional magnet.
