About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X5B
This AirTAC ASE40X5B is a single acting push cylinder with spring return, delivering a net push of 556.8 N at 0.5 MPa and 808.1 N at 0.7 MPa. Its ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight jigs and guards with ease.
With a 5 mm stroke and a male rod thread, it suits short, precise movements. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper absorbs end-of-stroke impact. For a safe working load, plan for about 34 kg of real work at 0.5 MPa, not the full rating, ensuring reliable operation.

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 ASE40X5B Is Used
Fixture Clamping
Use this cylinder to clamp small parts in a CNC fixture, where the 5 mm stroke and 556.8 N push securely hold components during machining.
Label Applicator
In a packaging line, this unit can press labels onto products with a quick, short push, fitting into the compact space between conveyor sections.
Ejector Pin
Injection mold ejector systems benefit from this cylinder's 5 mm stroke to push out small molded parts, with the spring return resetting the pin.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X5B the Right Cylinder?
For a lighter option, the ASE32X25 offers 352.5 N at 0.5 MPa, while the ASE50X25 provides 875.5 N for heavier tasks. This 40 mm bore unit is ideal for compact spaces where a short stroke and single-acting push are needed, but remember it does not hold mid-stroke position on air loss. The optional -S magnet is not fitted here, so no sensors can be mounted without it.
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 ASE40X5B FAQ
At 0.5 MPa, the push force is 556.8 N, and at 0.7 MPa, it is 808.1 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).
Yes, its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight jigs and guards. It has a fixed TPU bumper at both ends, and the optional -S magnet is not included in this model.
