Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X15
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X15 is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø40mm bore and 15mm 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 ASE40X15
This AirTAC ASE40X15 is a single acting compact cylinder that pushes with air and returns on a spring, so it needs just one air line. It delivers a net push of 556.8 N at 0.5 MPa (808.1 N at 0.7 MPa), already accounting for the spring's resistance, and requires a minimum of 0.2 MPa to start moving.
Its ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, which helps it fit into tight machine guarding and compact jigs. For a safe working load, plan for roughly 334 N (about 34 kg) of real work at 0.5 MPa, not the full rating, to leave a margin for friction and speed.

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 (Ø40mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 556.8 N |
| 0.7 MPa | 808.1 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 ASE40X15 Is Used
Jig Clamping
Use the 556.8 N push to clamp small parts in a drill jig, where the spring return releases the piece automatically when air is removed.
Label Applicator
Drive a label tamp head with the 15 mm stroke to press labels onto boxes, relying on the spring to retract the head between cycles.
Guard Interlock
Actuate a small safety gate latch with the compact body, saving space inside the machine frame while the spring ensures a fail-safe retracted position.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X15 the Right Cylinder?
For a lighter duty, the ASE32X25 offers 352.5 N at 0.5 MPa, while the ASE50X25 steps up to 875.5 N if you need more force. Since this is a spring-return model, it returns to its retracted position on air loss and does not hold a mid-stroke position. This version has no magnet, so order the -S option if you need to fit CMSE or DMSE sensors.
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 ASE40X15 FAQ
The net push force is 556.8 N at 0.5 MPa and 808.1 N at 0.7 MPa, both after accounting for the return spring. The minimum working pressure is 0.2 MPa, with a proof pressure of 1.5 MPa.
Only if you order the -S option, which adds a magnet to the piston. Without it, there is no magnet, so CMSE or DMSE switches cannot be mounted. The fixed TPU bumper at both ends absorbs energy at the end of stroke.
