Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X25S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X25S is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø16mm 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 ASE16X25S
This AirTAC ASE16X25S is a single acting push cylinder with spring return, so air extends the rod and the built-in spring pulls it back. At 0.5 MPa it delivers 78.4 N of push force net of the spring, and at 0.7 MPa that rises to 118.6 N, enough for light clamping or pushing tasks.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into tight machine guards and small jigs. The optional -S magnet is already fitted on this model, so you can add CMSE or DMSE reed switches for position sensing. For a safe working load, plan for about 47 N of real work at 0.5 MPa, which is roughly 4.8 kg of vertical lift with a 2:1 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 (Ø16mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 78.4 N |
| 0.7 MPa | 118.6 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 ASE16X25S Is Used
Small Part Ejection
Use the ASE16X25S to push small stamped parts off a die or into a chute in a stamping press, where the 78.4 N force at 0.5 MPa clears lightweight components without damage.
Jig Clamping
Mount this cylinder in a drill jig to hold thin workpieces against a stop during drilling. The spring return keeps the clamp open when air is off, and the compact body fits under a bench guard.
Label Applicator
In a packaging line, this cylinder can advance a label applicator head to press labels onto small boxes. The 25 mm stroke matches the label length, and the fixed TPU bumper prevents harsh stops.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X25S the Right Cylinder?
When sizing, compare this 16 mm bore with the 20 mm bore, which gives 127.4 N at 0.5 MPa, if you need more force in a similar footprint. The 25 mm stroke is the maximum standard for this bore, and the spring returns the rod to its home position on air loss, but it does not hold a mid-stroke position. With the -S magnet, CMSE or DMSE switches can be mounted in the body slots for reliable end-of-stroke detection.
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 ASE16X25S FAQ
The push force is 78.4 N at 0.5 MPa and 118.6 N at 0.7 MPa, 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 operating pressure range is 0.2-1.0 MPa (28-145 psi).
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in machine guards and small fixtures. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet on this model allows CMSE or DMSE switches to be mounted for sensing.
