Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X15S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X15S 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 ASE20X15S
This AirTAC ASE20X15S is a single acting push cylinder with spring return, meaning air extends the rod and the built-in spring retracts it. It delivers 127.4 N of push force at 0.5 MPa, net of the spring, and requires a minimum of 0.2 MPa to overcome the spring.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine guards and compact jigs. With the optional -S magnet fitted, you can mount CMSE or DMSE reed switches for position sensing. For a safe working load, plan for about 76 N (roughly 7.8 kg) of real work at 0.5 MPa, not the full 127.4 N rating.

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 ASE20X15S Is Used
Compact Jig Clamping
Use in a small pneumatic jig to clamp thin sheet metal parts during drilling. The 15 mm stroke and 127.4 N force at 0.5 MPa are enough for light fixtures where a full-size cylinder will not fit.
Label Applicator
Drive a label tamp head in a packaging line. The short stroke and spring return give a quick, repeatable push to apply labels to small cartons, and the M5x0.8 port simplifies air line routing.
Guard Door Interlock
Activate a small interlock pin on a machine guard. The spring retracts the rod when air is removed, so the pin releases and the guard can open. The compact body fits within a slim guard frame.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X15S the Right Cylinder?
For lighter applications, the ASE16X25 offers 78.4 N at 0.5 MPa, while the ASE25X25 steps up to 210.1 N. This 20 mm bore with a 15 mm stroke suits short, repetitive pushes in tight spaces. The spring returns the rod to its home position on air loss, but it does not hold a mid-stroke position. Choose FA or FB flange, LB foot, CA or CB clevis, CR, SDB pivot, or FTC brackets to match your fixture.
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 ASE20X15S FAQ
At 0.5 MPa, the push force is 127.4 N, and at 0.7 MPa it is 190.2 N. These figures are already net of the return spring, so they are the usable forces. The operating pressure range is 0.2-1.0 MPa (28-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in compact machine guards and gantries. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
