Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20SB 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 ASE32X20SB
This AirTAC ASE32X20SB is a single acting push cylinder with a spring return, so air extends the rod and the spring pulls it back. It delivers 352.5 N of push force at 0.5 MPa, already 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 guards. The optional -S magnet is fitted here, so CMSE or DMSE switches can be mounted for position sensing, and the male rod thread (B) simplifies direct coupling. For a safe working load, plan for about 211 N of real work at 0.5 MPa, which is roughly 21.5 kg of vertical lift with a 2:1 margin.

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 ASE32X20SB Is Used
Fixture Clamping
Use the 352.5 N push at 0.5 MPa to clamp small parts in a CNC fixture, where the spring return releases the part automatically when air is removed.
Label Applicator
Drive a label applicator head with the 20 mm stroke to press labels onto boxes, relying on the spring to retract the head between cycles.
Guard Door Lock
Mount on a machine guard to push a locking pin into place, with the spring retracting the pin when air is off, ensuring the guard stays closed.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20SB the Right Cylinder?
For a lighter duty, the ASE25X20 with a 25 mm bore gives 210.1 N at 0.5 MPa, while stepping up to the ASE40X20 provides 556.8 N at the same pressure. Since this is single acting, the spring retracts the rod on air loss, so it does not hold a mid-stroke position; use it for simple extend-and-return tasks. The 1/8" port and M8x1.25 male rod thread match common fittings, and the FA/FB flange or LB foot mounts bolt to the ISO 21287 face.
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 ASE32X20SB FAQ
At 0.5 MPa, the push force is 352.5 N, and at 0.7 MPa it is 513.4 N, both net of the return spring. The operating pressure range is 0.2-1.0 MPa (28-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits in small jigs and guards. The fixed TPU bumper absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE switches for position sensing.
