Airtac ACE Compact Cylinder ACE25X110S
The AirTAC Airtac ACE Compact Cylinder ACE25X110S 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 ACE25X110S
This AirTAC ACE25X110S is a double acting compact cylinder built to ISO 21287, with a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder. Its 25 mm bore delivers 245.4 N of push force at 0.5 MPa, and the fixed TPU bumper at each end absorbs impact without any adjustable air cushion.
Because the -S code is fitted, this model carries the optional magnet, so you can mount CMSE or DMSE reed or solid-state switches for position sensing. The M5x0.8 port and female M6x1.0 rod thread keep installation simple, and the S45C hard-chrome plated rod resists wear. For a real-world rule of thumb, plan on about 15 kg of safe vertical lift at 0.5 MPa, which is roughly 0.6 times the rated push force, so you can match it to an actual part weight.

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 ACE25X110S Is Used
Fixture Clamping
Use the ACE25X110S to clamp small parts in a CNC fixture, where its short ISO 21287 body fits under a guard and the 245.4 N push at 0.5 MPa holds a 2 kg workpiece securely.
Parcel Stop Gate
Mount this cylinder on a packaging conveyor to raise a stop gate for boxes up to 15 kg, using the 110 mm stroke to clear the path and the optional -S magnet to confirm the gate position with a CMSE switch.
Lab Test Probe
In a quality lab, this cylinder can drive a test probe into a sample at 30-500 mm/s, with the 206.2 N pull force at 0.5 MPa retracting the probe quickly between measurements.
Is the Airtac ACE Compact Cylinder ACE25X110S the Right Cylinder?
When sizing this ACE25X110S, compare it with the ACE20X110S which pushes 157.1 N at 0.5 MPa for lighter duties, or step up to the ACE32X110S which pushes 402.1 N at 0.5 MPa if you need more force. The 110 mm stroke fits within the 150 mm maximum standard stroke for this bore, so it is a standard order. Remember that this cylinder is double acting, so it needs air pressure to both extend and retract, and it will not hold a load if air is lost, so use a rod lock or pilot check valve for position holding.
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 ACE25X110S 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 proof pressure is 1.5 MPa (215 psi).
The ACE25X110S has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight jigs and guards. It uses a fixed TPU bumper at both ends to absorb impact, not an adjustable cushion, and the optional -S magnet allows CMSE or DMSE switches for position sensing.
