Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20S 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 ASE32X20S
This AirTAC ASE32X20S is a single acting push cylinder with 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 at 0.5 MPa and 513.4 N at 0.7 MPa, net of the return spring, and needs a minimum of 0.2 MPa to overcome that spring.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into tight jigs and guarded zones. The optional -S magnet is fitted here, so CMSE or DMSE switches can be mounted for position sensing. For a safe vertical lift, plan on about 21.5 kg at 0.5 MPa with a 2:1 margin, so match it to a real part weight.

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 ASE32X20S Is Used
Jig Clamping
Use it to clamp small parts in a CNC fixture. The 352.5 N push at 0.5 MPa holds components firmly, and the spring release clears the part quickly for the next cycle.
Label Applicator
Drive a label applicator head in a packaging line. The short ISO 21287 body fits under a guard, and the 20 mm stroke is enough to press labels onto cartons at speeds up to 500 mm/s.
Guard Door Interlock
Actuate a small guard door latch on a machine. The spring return pulls the latch back when air is removed, and the optional -S magnet lets a sensor confirm the door is closed.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20S the Right Cylinder?
For lighter duty, the ASE25X20 offers 210.1 N at 0.5 MPa, while the ASE40X20 steps up to 556.8 N at the same pressure. This 32 mm bore sits in the middle, giving a good balance of force and compact size. Since it is single acting, the spring returns the rod to its home position on air loss, but it does not hold a mid-stroke load. With the -S magnet, you can add CMSE or DMSE sensors for position feedback, and the 1/8" port is ready for standard fittings.
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 ASE32X20S FAQ
At 0.5 MPa, the push force is 352.5 N, and at 0.7 MPa it is 513.4 N. These 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 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces like under guards or inside gantries. It uses a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE switches for sensing.
