Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X10S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X10S is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø20mm bore and 10mm 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 ASE20X10S
This AirTAC ASE20X10S 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 127.4 N of push force, net of the return spring, which suits light clamping and indexing tasks.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit into tight machine guards and jigs. The optional -S magnet is fitted here, so CMSE or DMSE reed or solid-state switches can be mounted for position sensing. For a safe working load, plan on roughly 76 N (about 7.8 kg) of real work at 0.5 MPa, not the full 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 ASE20X10S Is Used
Jig Clamping
Clamp small parts in a CNC fixture with 127.4 N push at 0.5 MPa, and let the spring retract the pin for quick part changes.
Label Applicator
Drive a label tamp head forward with a 10 mm stroke to press labels onto boxes, then spring back for the next cycle.
Guard Door Latch
Push a latch pin into a machine guard frame with 127.4 N, and the spring releases it when air is removed for safe access.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X10S the Right Cylinder?
For a lighter duty, the ASE16X25 offers 78.4 N at 0.5 MPa, while stepping up to the ASE25X25 gives 210.1 N. This 20 mm bore with a 10 mm stroke is a good middle ground for compact pushes. Since it is single acting, the spring returns the rod on air loss, but it does not hold a mid-stroke position. Use FA/FB flange, LB foot, or CA/CB clevis mounts to fit standard ISO 21287 fixtures.
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 ASE20X10S FAQ
At 0.5 MPa the push force is 127.4 N, and at 0.7 MPa it is 190.2 N, 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 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in narrow machine guards and jigs. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors to be attached.
