Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X25B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X25B 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 ASE16X25B
This AirTAC ASE16X25B is a single acting push cylinder with spring return, so air extends the 8 mm rod and the built-in spring pulls it back when pressure drops. At 0.5 MPa it delivers 78.4 N of push force net of the spring, rising to 118.6 N at 0.7 MPa, which suits light clamping and indexing tasks in compact machinery.
Because it follows ISO 21287, the hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder of the same bore, letting it fit inside tight guarding or narrow jig frames. The male rod thread (B code) simplifies direct coupling to a tool, and the fixed TPU bumper at both ends absorbs end-of-stroke impact. For a safe working load, plan around 47 N at 0.5 MPa, which equals lifting about 4.8 kg vertically 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 (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 ASE16X25B Is Used
Jig Clamping
Use the 78.4 N push at 0.5 MPa to clamp small workpieces in a CNC fixture, where the spring return lifts the clamp off the part when air is removed.
Label Applicator
Drive a light label applicator head in a packaging line, with the 25 mm stroke pressing labels onto boxes and the spring retracting the head between cycles.
Guard Door Interlock
Activate a safety interlock pin on a machine guard, using the spring return to pull the pin back when air is cut, ensuring the guard stays closed without power.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE16X25B the Right Cylinder?
Choose this ASE16X25B when you need a compact, spring-return actuator for short strokes up to 25 mm and light loads. If your application requires more force, step up to the 20 mm bore, which pushes 127.4 N at 0.5 MPa; for lighter work, the 12 mm bore offers 40.0 N at 0.5 MPa. Remember, the spring returns the rod to its retracted position on air loss, so it will not hold a mid-stroke position.
This model has no magnet, so it cannot trigger CMSE or DMSE sensors; order the -S version if you need position sensing. The M5x0.8 port suits small-bore piping, and the male rod thread allows direct mounting of fixtures without a rod-end adapter.
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 ASE16X25B FAQ
At 0.5 MPa, the push force is 78.4 N net of the return spring; at 0.7 MPa it is 118.6 N. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). 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 of the same bore, so it fits in confined jigs or behind panels. It has a fixed TPU bumper at both ends to absorb impact, and the male rod thread (B) allows direct tool mounting. This model has no magnet, so sensors are only possible with the optional -S version.
