Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X20SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X20SB is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø20mm bore and 20mm 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 ASE20X20SB
This is a single acting push cylinder with spring return, meaning air extends the rod and the spring retracts it, needing only one air line. At 0.5 MPa it delivers 127.4 N of push force (net of the spring), which is enough for light clamping or small part ejection tasks.
Its ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight jigs and guards. The optional -S magnet is fitted here, so CMSE or DMSE switches can be mounted for position sensing. For real work, plan on about 76 N (0.6 times the 0.5 MPa rating) to keep a safety margin, which is roughly equivalent to lifting 7.8 kg vertically 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 ASE20X20SB Is Used
Jig Clamping
Use this cylinder to clamp small parts in a drill jig or fixture, where the 127.4 N force at 0.5 MPa holds components securely during machining.
Parts Ejection
In an assembly line, mount it to push finished parts off a conveyor into a bin. The 20 mm stroke is enough for small items, and the spring retract clears the path quickly.
Label Applicator
Drive a label applicator head to press labels onto small packages. The compact body fits under a packaging station, and the repeatable push ensures consistent placement.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X20SB the Right Cylinder?
When sizing, compare this 20 mm bore with the smaller 16 mm bore (78.4 N at 0.5 MPa) and the larger 25 mm bore (210.1 N at 0.5 MPa). Choose the 20 mm if you need moderate force in a compact space, but remember it is single acting, so it cannot hold a mid-stroke position on air loss; the spring returns it home. The male rod thread (B code) simplifies mounting with rod-end accessories, and the M5x0.8 port suits small-bore pneumatic circuits.
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 ASE20X20SB FAQ
At 0.5 MPa, the push force is 127.4 N; at 0.7 MPa, it is 190.2 N. These are net of the return spring, so they are the usable forces to move a load. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (145 psi).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is ideal for tight spaces. It has a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet (fitted here) allows CMSE or DMSE switches for position sensing.
