Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20 is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø32mm bore and 20mm stroke, 1/8" 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 ASE32X20
This AirTAC ASE32X20 is a single acting compact cylinder, spring-return, so air extends the rod and the built-in spring retracts it. With a 32 mm bore it delivers 352.5 N of push force at 0.5 MPa, net of the return spring, and needs a minimum of 0.2 MPa to overcome the spring.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting it fit into tight jigs and guards. For a 2:1 safety margin, plan to lift about 18 kg vertically with this unit at 0.5 MPa, not the full rated force.

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 (Ø32mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 352.5 N |
| 0.7 MPa | 513.4 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 ASE32X20 Is Used
Jig Clamping
Use in a compact clamping fixture on a CNC machine to push a part against a stop. The 352.5 N force at 0.5 MPa secures small components, and the short body fits under a guard.
Label Applicator
Drive a label applicator head in a packaging line. The 20 mm stroke and spring return provide a quick, repeatable push to press labels onto boxes, with the TPU bumper absorbing end-of-stroke impact.
Parts Ejector
Eject a finished part from a die or mold after processing. The single-acting push with spring return retracts the rod automatically, clearing the area for the next cycle, and the compact body mounts in tight spaces.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20 the Right Cylinder?
Choose this ASE32X20 when you need a compact, single-acting push with a spring return and a 20 mm stroke. Compare with the ASE25X20 (210.1 N at 0.5 MPa) for lighter loads, or step up to the ASE40X20 (556.8 N at 0.5 MPa) for more force. The spring returns the rod to its home position on air loss, so it does not hold a mid-stroke position. Order with the -S code to add the optional magnet for CMSE or DMSE sensors.
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 ASE32X20 FAQ
The ASE32X20 is single acting push, spring return. At 0.5 MPa it delivers 352.5 N of push force, and at 0.7 MPa it delivers 513.4 N. These values are net of the return spring, so they are the usable forces. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight jigs and gantries. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the hard-anodized aluminium body resists wear. You can add the optional -S magnet for CMSE or DMSE sensors, and mount it with FA, LB, CA, or other brackets.
