Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X15
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X15 is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 15mm stroke, M5×0.8 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 ASE25X15
This AirTAC ASE25X15 is a single acting cylinder that pushes with air and retracts via a return spring, requiring only one air line. It delivers a net push force of 210.1 N at 0.5 MPa and 308.3 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa to overcome the spring.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight machine guarding and fixtures. The hard-anodized aluminum body with a hard-chrome plated S45C rod resists wear, while fixed TPU bumpers at both ends absorb end-of-stroke impact. For a safe working load, plan for roughly 126 N of real work at 0.5 MPa, which equates to lifting about 13 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 (Ø25mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 210.1 N |
| 0.7 MPa | 308.3 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 ASE25X15 Is Used
Jig Clamping
Use in a manual assembly jig to clamp small plastic housings with a controlled 210 N force before screw driving, saving space in a compact work cell.
Label Applicator
Drive a label tamp head on a packaging line with a 15 mm stroke to press labels onto product cartons, providing consistent pressure without excess bulk.
Guard Door Latch
Actuate a safety guard latch on a small machine tool, using the spring return to automatically retract the latch when air is removed for safe access.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE25X15 the Right Cylinder?
For lighter duty, the ASE20X15 offers 127.4 N at 0.5 MPa, while the ASE32X15 provides 352.5 N for more demanding applications. This 25 mm bore size suits medium-force operations where space is limited. Since this model lacks the optional -S magnet, it cannot accommodate CMSE or DMSE sensors; order the -S code if position sensing is required. The spring returns the rod to its home position on air loss and does not hold a mid-stroke position.
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 ASE25X15 FAQ
The ASE25X15 provides a net push force of 210.1 N at 0.5 MPa and 308.3 N at 0.7 MPa, already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
No, this model does not have a magnet, so CMSE or DMSE sensors cannot be used. To enable sensor mounting, you must order the ASE25X15S with the optional -S magnet. The cylinder uses a compact ISO 21287 body with fixed TPU bumpers for end-of-stroke deceleration.
