Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X15
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X15 is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø20mm 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 ASE20X15
This ASE20X15 is a single acting push cylinder with spring return, extending on air and retracting via the built-in spring. It delivers 127.4 N of net push force at 0.5 MPa, enough for light clamping or positioning tasks in compact automation cells.
The ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, making it a fit for tight guarding and tooling envelopes. For real work, plan around 76 N at 0.5 MPa, which equals a safe vertical lift of roughly 7.8 kg with a 2:1 margin. The fixed TPU bumper absorbs end-of-stroke impact, and the hard-anodized aluminium body with S45C hard-chrome rod resists wear in cyclic duty.

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 (Ø20mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 127.4 N |
| 0.7 MPa | 190.2 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 ASE20X15 Is Used
Fixture Clamping
Use the 127.4 N push at 0.5 MPa to clamp thin sheet metal parts against a locating pin in a drill jig, where the short body fits under the work surface.
Carton Ejection
Mount on a packaging line to push small cartons off a conveyor onto a chute; the 15 mm stroke clears the edge without wasting cycle time.
Guard Interlock
Actuate a mechanical interlock pin on a machine guard door, using the spring return to retract the pin when air is removed for safety.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X15 the Right Cylinder?
Compare this 20 mm bore against a smaller 16 mm bore (78.4 N at 0.5 MPa) if your load is light, or step up to a 25 mm bore (210.1 N at 0.5 MPa) when you need more push. The 15 mm stroke suits short transfer or ejection moves; note that the spring returns the rod to home on air loss and does not hold a mid-stroke position.
This unit has no magnet, so no CMSE or DMSE sensor can be fitted unless you order the optional -S magnet version. The M5x0.8 port and female M6x1.0 rod thread suit compact manifolds and small tooling attachments.
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 ASE20X15 FAQ
The ASE20X15 delivers 127.4 N push at 0.5 MPa and 190.2 N push at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi).
No, this version has no magnet, so no CMSE or DMSE switch can be mounted. You must order the ASE20X15S with the optional -S magnet to use reed or solid-state sensors. The fixed TPU bumper at both ends handles end-of-stroke impact.
