Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X5SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X5SB 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 ASE20X5SB
This AirTAC ASE20X5SB 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) from a compact ISO 21287 body. The 5 mm stroke suits short indexing moves, and the male rod thread (B code) simplifies mounting with rod-end accessories.
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits inside tight machine guards and small jigs. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. For real work, plan on about 76 N (0.6 times the 0.5 MPa rating) to keep a safety margin, or about 8 kg of vertical lift with a 2:1 factor.

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 ASE20X5SB Is Used
Jig Clamping
Use the 5 mm stroke to clamp small parts in a CNC fixture. The 127.4 N push at 0.5 MPa holds light workpieces, and the compact body fits under a low-profile clamp arm.
Parts Ejector
In a stamping press, this cylinder ejects a small blank from a die. The spring return clears the die area quickly, and the fixed TPU bumper absorbs the end-of-stroke impact without noise.
Sorting Gate
On a small conveyor, the ASE20X5SB diverts lightweight boxes into a reject chute. The -S magnet allows a DMSE solid-state switch to confirm the gate position each cycle.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X5SB the Right Cylinder?
Choose this ASE20X5SB for short, spring-return pushes up to 5 mm. If you need more force, the ASE25 bore offers 210.1 N at 0.5 MPa, while the ASE16 provides 78.4 N for lighter tasks. The spring retracts the rod on air loss, so it does not hold a mid-stroke position; use it for simple extend-and-release actions. The male rod thread (B) and M5x0.8 port are ready for direct connection, and the fitted -S magnet lets you add CMSE or DMSE sensors for cycle confirmation.
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 ASE20X5SB FAQ
The push force is 127.4 N at 0.5 MPa and 190.2 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi). Operating pressure range is 0.2-1.0 MPa (28-145 psi).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits inside machine guards and small fixtures. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the optional -S magnet enables CMSE or DMSE sensors for position feedback.
