Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X5SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X5SB 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 ASE25X5SB
This AirTAC ASE25X5SB is a single acting push cylinder with spring return, delivering 210.1 N of push force at 0.5 MPa (net of the return spring). Its 5 mm stroke suits short indexing tasks, and the ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, easing installation in tight fixtures.
The optional -S magnet is fitted here, so CMSE or DMSE reed and solid-state switches can mount directly to sense the piston position. For real work, plan on roughly 126 N (about 0.6 times the 0.5 MPa rating) to keep a safety margin; this translates to lifting about 13 kg vertically 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 (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 ASE25X5SB Is Used
Fixture Clamping
Use the 5 mm stroke to clamp small parts in a jig for drilling or light assembly, with the spring retracting the rod when air is off.
Tolerance Gauging
In a quality lab, this cylinder can push a probe against a part to check dimensional tolerance, relying on the short stroke for repeatable contact.
Label Pressing
On a packaging line, press a label or film onto a product with a gentle 210 N force at 0.5 MPa, then let the spring lift the head for the next cycle.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X5SB the Right Cylinder?
For a lighter push, the 20 mm bore ASE20X5 provides 127.4 N at 0.5 MPa, while stepping up to the 32 mm bore ASE32X5 gives 352.5 N at the same pressure. Since this is single acting with spring return, the rod retracts when air is removed; it does not hold a mid-stroke position, so use it for push-and-release actions. The male rod thread (B) simplifies mounting to a clevis or rod end, 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 ASE25X5SB FAQ
At 0.5 MPa, the push force is 210.1 N; at 0.7 MPa, it is 308.3 N. These are net of the return spring, so they are the usable forces at the rod. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The ASE25X5SB has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, so it fits into compact jigs or guards. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors to detect the piston position.
