Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X15SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X15SB is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø20mm 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 ASE20X15SB
This AirTAC ASE20X15SB is a single acting, spring-return compact cylinder that extends its 10 mm rod with air and retracts it with a built-in spring, so it needs just one air line. At 0.5 MPa it delivers 127.4 N of push force (net of the spring), which translates to a safe working load of about 76 N or roughly 7.8 kg when you apply a 2:1 safety margin for vertical lifting.
Its ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit into tight jigs and guards. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and the fixed TPU bumper at both ends absorbs end-of-stroke energy. The male rod thread (B code) simplifies mounting, and this model carries the optional -S magnet, so you can add CMSE or DMSE reed or solid-state switches for position sensing.

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 (Ø20mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 127.4 N |
| 0.7 MPa | 190.2 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 ASE20X15SB Is Used
Tight Jig Clamping
Use the ASE20X15SB to clamp small parts in a CNC fixture where the 50% shorter ISO 21287 body clears the spindle and guards, with 127.4 N holding a lightweight workpiece during drilling.
Label Applicator
In a packaging line, this cylinder can push a label applicator head forward 15 mm to press labels onto boxes, with the spring returning it quickly for the next cycle at speeds up to 500 mm/s.
Guard Door Latch
Mount it as a latch on a machine guard door: air extends the rod to lock the door closed, and the spring retracts it when you release pressure, providing a simple safety interlock in a compact space.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X15SB the Right Cylinder?
For a lighter push, the ASE16X15 offers 78.4 N at 0.5 MPa, while the ASE25X15 steps up to 210.1 N at the same pressure, so you can size up or down based on your actual load. Remember, this is single acting: the spring retracts the rod, so it does not hold a mid-stroke position if air pressure is lost; it returns to the home position. The M5x0.8 port suits small-bore applications, and the male rod thread (B) lets you connect directly to a load without a separate rod-end accessory.
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 ASE20X15SB FAQ
At 0.5 MPa, the push force is 127.4 N (net of the return spring), and at 0.7 MPa it rises to 190.2 N. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). The operating pressure range is 0.2-1.0 MPa (28-145 psi).
Yes, this ASE20X15SB includes the optional -S magnet, which is not standard on all ASE cylinders. With this magnet, you can mount CMSE or DMSE reed or solid-state switches to detect the piston position. Without the -S code, no magnet is present.
