Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X25SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X25SB is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 25mm 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 ASE25X25SB
This AirTAC ASE25X25SB is a single acting push cylinder with spring return, delivering 210.1 N of push force at 0.5 MPa and 308.3 N at 0.7 MPa, net of the return spring. Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight machine guarding and fixture spaces where a full-length unit will not go.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling. The male rod thread (B code) simplifies mounting of custom tooling. For a 2:1 safety margin, plan to lift about 10.7 kg vertically with this unit at 0.5 MPa, and keep real workloads near 126 N for reliable operation.

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 ASE25X25SB Is Used
Jig Clamping
Use the 210.1 N push to clamp small plastic housings in a drilling jig, with the spring return clearing the part for fast manual loading.
Label Applicator
Drive a label tamp head for 25 mm of travel on a carton sealing line, where the compact body fits between existing guide rails.
Guard Door Latch
Actuate a safety interlock latch on a light machine guard, using the spring return to retract the bolt when air is removed.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X25SB the Right Cylinder?
For lighter duties, the 20 mm bore ASE20X25 produces 127.4 N at 0.5 MPa, while stepping up to the 32 mm bore ASE32X25 gives 352.5 N for heavier parts. This 25 mm bore model suits medium-force applications where the 25 mm stroke matches the cycle. The return spring retracts the rod on air loss, so it does not hold a mid-stroke position. The -S code means the magnet is fitted for CMSE or DMSE switches, and the M5x0.8 port suits small-bore air lines.
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 ASE25X25SB FAQ
At 0.5 MPa, the push force is 210.1 N; at 0.7 MPa, it is 308.3 N. These figures are net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in confined machine areas. It has a fixed TPU bumper at both ends, and the optional -S magnet enables CMSE or DMSE switch mounting for position sensing.
