Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25 is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø32mm bore and 25mm 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 ASE32X25
This AirTAC ASE32X25 is a single acting, spring-return compact cylinder that extends under air pressure and retracts via an internal spring, requiring only one air line. With a 32 mm bore and 25 mm stroke, it delivers 352.5 N of push force at 0.5 MPa (net of the spring), making it a straightforward choice for light automation tasks.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guarded areas where a full-length cylinder won't. The optional -S magnet enables CMSE or DMSE switches for position sensing, but without it, no sensor can be mounted. For a safe working load, plan for about 211 N of real work at 0.5 MPa, which translates to lifting roughly 21.5 kg vertically with a 2:1 safety 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 ASE32X25 Is Used
Jig Clamping
Use in a compact clamping jig on a CNC mill where the 25 mm stroke and 352.5 N force at 0.5 MPa securely hold small parts during drilling, and the spring retracts the clamp when air is removed.
Sorting Gate
Mount on a packaging conveyor to divert lightweight boxes into a reject lane; the short body fits under the belt guard, and the spring return resets the gate automatically after each cycle.
Guard Interlock
Actuate a safety guard latch on a small assembly station, where the 25 mm stroke pushes a bolt into a receiver, and the spring pulls it back when the air supply is cut for maintenance.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25 the Right Cylinder?
When sizing, compare this 32 mm bore to a smaller 25 mm bore (210.1 N at 0.5 MPa) if you need less force, or step up to a 40 mm bore (556.8 N at 0.5 MPa) for more capacity. The spring returns the rod to its home position on air loss, but it does not hold a mid-stroke position, so plan for that in your circuit design. Choose the -S code if you need the magnet for CMSE or DMSE sensors, and select from FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC mounts to match your fixture.
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 ASE32X25 FAQ
The ASE32X25 delivers 352.5 N of push force at 0.5 MPa and 513.4 N at 0.7 MPa, both net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
Sensors like CMSE or DMSE switches are only possible if you order the -S code, which adds the optional magnet. Without -S, there is no magnet, so no sensor can be mounted. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder.
