Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20B 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 ASE32X20B
This is a single acting push cylinder with spring return, meaning air extends the rod and the internal spring retracts it, so it needs only one air line and rests retracted when pressure is off. The 32 mm bore delivers 352.5 N of push at 0.5 MPa, net of the return spring, so you can plan real work around that figure rather than the raw bore area.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit inside tight jigs and guards where a full-length cylinder would not. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and a fixed TPU bumper at each end absorbs end-of-stroke impact. For a safe working load, plan for about 21 kg of vertical lift at 0.5 MPa, applying a 2:1 margin to the 352.5 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 (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 ASE32X20B Is Used
Jig Clamping
Use the 352.5 N push at 0.5 MPa to clamp small parts in a drill jig, where the compact body fits under a worktable and the spring retracts the clamp when air is removed.
Label Applicator
Drive a label applicator head for a 20 mm stroke on a packaging line, relying on the spring return to lift the head after each cycle and the TPU bumper to prevent part damage.
Guard Interlock
Actuate a small safety guard interlock on a machine tool, where the single-acting push extends a pin and the spring pulls it back, with the short body fitting inside a confined enclosure.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X20B the Right Cylinder?
For lighter work, the 25 mm bore gives 210.1 N at 0.5 MPa, while stepping up to the 40 mm bore raises that to 556.8 N at the same pressure, so you can match the force to your fixture. The 20 mm stroke is well within the 200 mm maximum standard for this bore, and the male rod thread (B code) simplifies mounting with rod-end accessories. Since this model has no magnet, it cannot accept CMSE or DMSE sensors; order the -S option if you need position sensing. The spring returns the rod home on air loss, but it does not hold a mid-stroke position, so design for a retracted rest state.
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 ASE32X20B 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 minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). Operating pressure range is 0.2-1.0 MPa (28-145 psi).
No, this model has no magnet, so CMSE or DMSE switches cannot be mounted. You would need to order the -S option to get the built-in magnet for sensor compatibility. The cylinder uses a fixed TPU bumper at both ends, and its compact ISO 21277 body is about 50% shorter than an ISO 15552 profile cylinder.
