Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X5B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X5B is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø20mm bore and 5mm 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 ASE20X5B
This AirTAC ASE20X5B is a single acting push cylinder with spring return, delivering 127.4 N of push force at 0.5 MPa (net of the return spring). Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for tight spaces where a full-length cylinder will not fit.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in repetitive cycles. A fixed TPU bumper absorbs energy at both ends, and the minimum working pressure is 0.2 MPa. For a safe working load, plan for roughly 76 N (about 7.8 kg vertically with a 2:1 margin) rather than the full 127.4 N rating.

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 ASE20X5B Is Used
Jig Clamping
Use in a compact jig to clamp small plastic parts during drilling. The 5 mm stroke and 127.4 N force at 0.5 MPa hold components firmly without occupying much fixture space.
Guard Door Latch
Mount on a machine guard to push a latch pin into place. The spring return retracts the rod when air is removed, keeping the guard closed and safe.
Label Applicator
Drive a small label stamping head in a packaging line. The short 5 mm stroke cycles quickly within the 50-500 mm/s speed range, applying consistent pressure.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X5B the Right Cylinder?
For a lighter push, the 16 mm bore ASE16X5 offers 78.4 N at 0.5 MPa, while stepping up to the 25 mm bore ASE25X5 provides 210.1 N. This 20 mm bore model has a male rod thread (B code) and M5x0.8 port. Since there is no -S code, this unit has no magnet, so CMSE or DMSE sensors cannot be mounted without ordering the optional -S version.
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 ASE20X5B FAQ
At 0.5 MPa, the push force is 127.4 N; at 0.7 MPa, it is 190.2 N. These values are net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
No, this ASE20X5B has no magnet because the -S option was not ordered. To use CMSE or DMSE reed or solid-state switches, you must order the model with the -S suffix, which adds the optional magnet.
