Airtac ACE Compact Cylinder ACE25X100S
The AirTAC Airtac ACE Compact Cylinder ACE25X100S is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 100mm 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 ACE25X100S
The ACE25X100S is a double acting ISO 21287 compact cylinder that extends and retracts its 10 mm rod with air pressure on both strokes. Its 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 of an ISO 15552 profile cylinder. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling, and the fixed TPU bumper at each end absorbs end-of-stroke impact without needing adjustment.
This model carries the optional -S magnet, so you can fit CMSE or DMSE reed or solid-state switches to confirm rod position. For a real-world load estimate, plan for about 15 kg of safe vertical work at 0.5 MPa (245.4 N x 0.6 divided by 9.81), which gives you a 2:1 margin over the theoretical rating. The M5x0.8 port suits small-bore air circuits, and the female M6x1.0 rod thread accepts standard clevis or knuckle fittings.

Where the Airtac ACE Compact Cylinder ACE25X100S Is Used
PCB Guide Pin Pusher
Use the ACE25X100S to push a guide pin into a PCB fixture during assembly. The 245.4 N push force at 0.5 MPa moves the pin smoothly, and the compact body fits under the worktable where a longer cylinder would not.
Carton Flap Folder
Mount the ACE25X100S on a carton erecting machine to fold the bottom flaps of a small box. The 100 mm stroke covers the flap width, and the fixed TPU bumper prevents jarring at the end of each cycle, keeping the box stable.
Sorting Gate Actuator
In a conveyor sorting system, the ACE25X100S diverts lightweight parcels to a side lane. The 206.2 N retract force at 0.5 MPa pulls the gate back quickly, and the optional -S magnet lets a CMSE switch confirm the gate is fully open or closed.
Is the Airtac ACE Compact Cylinder ACE25X100S the Right Cylinder?
Choose the ACE25X100S when you need a 100 mm stroke in a compact envelope. If your application demands more force, step up to the ACE32X100 with 402.1 N push at 0.5 MPa; if you need less, the ACE20X100 provides 157.1 N. The 100 mm stroke is within the 150 mm maximum standard stroke for this bore, so no custom order is required. This model includes the -S magnet, so order CMSE or DMSE switches separately to sense the piston position. For mounting, use FA or FB flanges, LB foot brackets, or CA/CB clevis mounts that bolt to 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 ACE25X100S 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 is 50.1 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the speed range is 30-500 mm/s.
The ACE25X100S has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. This lets you install it in jigs, guards, or gantries where a full-length cylinder would not fit. The fixed TPU bumper at both ends absorbs impact, and the optional -S magnet enables CMSE or DMSE switch mounting for position sensing.
