Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X5S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X5S is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 5mm 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 ASE Single Acting Plunger Type Compact Air Cylinder ASE25X5S
This AirTAC ASE25X5S is a single acting push cylinder with spring return, so air extends the rod and the built-in spring retracts it. At 0.5 MPa it delivers 210.1 N of push force net of the spring, and at 0.7 MPa that rises to 308.3 N, making it a compact workhorse for light automation tasks.
The ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, which lets it fit into tight jigs and guards. Since this model carries the optional -S magnet, you can add CMSE or DMSE reed and solid-state switches for position sensing. For a safe working load, plan on about 126 N of real work at 0.5 MPa, or roughly 13 kg of vertical lift with a 2:1 safety margin.

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 (spring return) |
|---|---|
| 0.5 MPa | 210.1 N |
| 0.7 MPa | 308.3 N |
Single-acting push: air extends the rod; the return spring retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa. Single-acting strokes are short (Ø12 to 10 mm, Ø16-100 to 25 mm).

Where the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X5S Is Used
Tight Jig Clamping
Use the 5 mm stroke to clamp small parts in a CNC fixture, where the compact body fits between guide rails and the 210.1 N push holds a lightweight workpiece securely.
Label Applicator
Drive a label tamp head in a packaging line, using the short stroke to press labels onto boxes with a controlled 5 mm motion and reliable spring return between cycles.
Sensor Actuation
Trigger a limit switch or proximity sensor in an assembly station, where the 5 mm travel and the optional -S magnet allow precise position detection via CMSE or DMSE switches.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X5S the Right Cylinder?
When sizing, compare this 25 mm bore to the 20 mm bore which pushes 127.4 N at 0.5 MPa, or step up to the 32 mm bore for 352.5 N at the same pressure. The 5 mm stroke is short, so this unit suits precise, small movements rather than long travel. Remember the spring returns the rod to its home position on air loss, so it will not hold a mid-stroke position. Choose FA or FB flange, LB foot, CA or CB clevis, CR, SDB pivot, or FTC brackets to match your fixture, and order the -S magnet version for 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 0.2 – 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 Single-acting: do not force the rod against the spring.
- check Installation by qualified personnel per AirTAC docs.
Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X5S FAQ
At 0.5 MPa, the push force is 210.1 N, and at 0.7 MPa it is 308.3 N, both net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits into tight spaces. It has a fixed TPU bumper at both ends to absorb end-of-stroke energy, and the optional -S magnet enables CMSE or DMSE sensor mounting.
