Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X15B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X15B is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 15mm 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 ASE25X15B
This AirTAC ASE25X15B is a single acting push cylinder with spring return, delivering 210.1 N of push force at 0.5 MPa. Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight machine guarding and jigs where space is at a premium. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling.
With a 25 mm bore and 15 mm stroke, this unit is built for short, repetitive motions. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the two-way piston seal stores grease for low maintenance. For a safe working load, plan for about 126 N of real work at 0.5 MPa, which translates to lifting roughly 13 kg vertically with a 2:1 safety margin. The male rod thread (B code) simplifies direct attachment to tooling without a coupler.

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 ASE25X15B Is Used
Jig Clamping
Use in a drilling jig to push a locating pin into a workpiece. The 210.1 N force at 0.5 MPa holds parts firmly during machining, and the compact body fits under the fixture table.
Label Applicator
Drive a label tamp head in a packaging line. The 15 mm stroke cycles quickly at up to 500 mm/s, and the spring return lifts the head clear after each application.
Guard Door Interlock
Actuate a small safety interlock bolt on a machine guard. The spring return ensures the bolt retracts when air is removed, and the short body mounts inside the guard frame.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X15B the Right Cylinder?
When sizing, compare this 25 mm bore against the 20 mm bore, which offers 127.4 N at 0.5 MPa, or the 32 mm bore at 352.5 N for heavier loads. This model suits applications needing a compact footprint with moderate force. Remember, the spring retracts the rod on air loss, so it does not hold a mid-stroke position. The port is M5x0.8, and the maximum standard stroke for this bore is 25 mm, so this 15 mm stroke is well within standard range.
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 ASE25X15B FAQ
The ASE25X15B delivers 210.1 N push force at 0.5 MPa and 308.3 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa to overcome the spring, and the proof pressure is 1.5 MPa (215 psi). Operating pressure range is 0.2-1.0 MPa (28-145 psi).
No, this model is ordered without the optional -S magnet, so no CMSE or DMSE switch can be mounted. The magnet is only available when you order the -S code. The fixed TPU bumper at both ends handles end-of-stroke impact without adjustment.
