About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X5SB
This AirTAC ASE40X5SB is a single acting push cylinder with spring return, delivering 556.8 N of force at 0.5 MPa and 808.1 N at 0.7 MPa, net of the return spring. Its 5 mm stroke and compact ISO 21287 body save about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight automation cells.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling. The optional -S magnet is fitted on this model, enabling CMSE or DMSE reed and solid-state sensors for position detection. For a safe working load, plan for about 334 N of real work at 0.5 MPa, which lifts about 34 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 (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 ASE40X5SB Is Used
Jig Clamping
Use this 40 mm bore cylinder to clamp small parts in a CNC fixture. The 556.8 N push holds components securely during drilling, while the spring retract clears the work area fast.
Parts Ejection
Mount this cylinder behind a stop pin to eject finished parts from a press die. The 5 mm stroke is enough to push a stamped bracket off the locating pin, and the spring returns the pin for the next cycle.
Gate Stop
Install this cylinder on a conveyor to raise a stop gate for product separation. The 556.8 N force at 0.5 MPa is sufficient to hold back lightweight boxes, and the compact body fits under the conveyor frame.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X5SB the Right Cylinder?
For a lighter duty, the ASE32X25 offers 352.5 N at 0.5 MPa, while the ASE50X25 provides 875.5 N for heavier parts. This 40 mm bore with a 5 mm stroke suits short, rapid movements where space is limited. The spring returns the rod to its home position on air loss; it does not hold a mid-stroke position. The male rod thread (B code) simplifies direct coupling to tooling, and the 1/8" port matches standard fittings.
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 ASE40X5SB FAQ
The ASE40X5SB delivers 556.8 N push at 0.5 MPa and 808.1 N push at 0.7 MPa, both net of the return spring. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (145 psi). Proof pressure is 1.5 MPa (215 psi).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits inside guards and tight gantries. The fixed TPU bumper absorbs end-of-stroke impact, and the optional -S magnet on this model allows CMSE or DMSE sensors to detect the piston position.
