Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X10SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X10SB is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø20mm bore and 10mm 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 ASE20X10SB
This ASE20X10SB is a single acting push cylinder with spring return, extending its 10 mm stroke on air pressure and retracting automatically when pressure drops. It delivers 127.4 N of push force at 0.5 MPa, already net of the return spring, so you can size it directly for your application without derating for spring resistance.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight jigs and guards where a full-length unit won't. The optional -S magnet is fitted here, enabling CMSE or DMSE reed and solid-state switches for position sensing. For a safe vertical lift, plan for about 7.8 kg at 0.5 MPa, applying a 2:1 margin to the rated force.

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 ASE20X10SB Is Used
Tight Jig Clamping
Mount this 20 mm bore cylinder inside a compact fixture to clamp small parts during CNC drilling, using the 127.4 N push to hold components firmly in place.
Small Part Ejection
Use the 10 mm stroke to eject blister-pack pills or small electronic components from a forming die, with the spring retracting the rod for the next cycle.
Gate Stop on Conveyor
In a light assembly line, this cylinder extends to stop a lightweight carton at a work station, then retracts to let it pass, fitting within the conveyor guard's limited space.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X10SB the Right Cylinder?
When selecting between bores, compare the 20 mm bore's 127.4 N push at 0.5 MPa against the 16 mm bore's 78.4 N or the 25 mm bore's 210.1 N to match your load. This model has a male rod thread (B code) and M5x0.8 port, with a maximum standard stroke of 25 mm. The spring returns the rod to its retracted position on air loss, but it does not hold a mid-stroke position, so use mechanical guides for positioning. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face.
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 ASE20X10SB 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, so they represent the usable force at the rod. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight mounts. This model includes the optional -S magnet, so you can attach CMSE or DMSE sensors for position feedback. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and mounting brackets like FA, LB, or CA bolt directly to the face.
