Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X15SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X15SB 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 ASE40X15SB
This AirTAC ASE40X15SB is a single acting push cylinder with spring return, so air extends the rod and the spring pulls it back. It delivers a net push of 556.8 N at 0.5 MPa and 808.1 N at 0.7 MPa, already accounting for the return spring, with a minimum working pressure of 0.2 MPa.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for tight fixtures. As a practical guide, plan for about 334 N of real work at 0.5 MPa, which translates to lifting roughly 34 kg vertically with a 2:1 safety margin. The male rod thread (B code) simplifies mounting, and the optional -S magnet is fitted here for CMSE or DMSE sensors.

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 ASE40X15SB Is Used
Jig Clamping
Use the 556.8 N push to clamp small parts in a drill jig. The compact body fits under a worktable, and the spring return clears the part automatically when air is released.
Label Applicator
Drive a labeling head to press labels onto boxes. The 15 mm stroke and 808.1 N at 0.7 MPa provide a firm, quick press, while the short body fits within the machine guard.
Guard Door Latch
Actuate a safety latch on a machine guard. The spring return ensures the latch retracts when air is off, and the TPU bumper absorbs the end-of-stroke impact.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X15SB the Right Cylinder?
For lighter duty, the 32 mm bore offers 352.5 N at 0.5 MPa, while stepping up to the 50 mm bore provides 875.5 N. This 40 mm version suits mid-range applications where space is limited. Remember, the spring returns the rod to its retracted position on air loss and does not hold a mid-stroke position. The male rod thread and the -S magnet for sensor feedback are key options to verify for your setup.
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 ASE40X15SB FAQ
The net push force is 556.8 N at 0.5 MPa and 808.1 N at 0.7 MPa, with the return spring force already subtracted. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight areas. It uses a fixed TPU bumper at both ends for noise reduction. The optional -S magnet allows CMSE or DMSE sensors to be mounted for position feedback.
