Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X10B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X10B 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 ASE20X10B
This AirTAC ASE20X10B is a single acting push cylinder with spring return, meaning air extends the rod and the built-in spring retracts it. With a 20 mm bore, it delivers 127.4 N of push force at 0.5 MPa (net of the spring), making it a compact workhorse for light automation tasks.
Its ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length unit will not. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper at both ends absorbs end-of-stroke impact. For a safe working load, plan for about 76 N (0.6 x 127.4 N) of real work at 0.5 MPa, which translates to lifting roughly 7.8 kg vertically with a 2:1 safety margin.

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 ASE20X10B Is Used
Fixture Clamping
Use in a jig to clamp small plastic parts during drilling or gluing. The 127.4 N push at 0.5 MPa holds parts firmly, and the spring retracts the rod to clear the workspace automatically.
Carton Ejection
In a packaging line, this cylinder can push a folded carton out of a forming nest. The 10 mm stroke is enough to clear the part, and the compact body fits between conveyor rails.
Guard Door Latch
Mount on a machine guard to release a latch pin. The spring return ensures the pin retracts when air is off, and the short stroke suits the small movement needed for safety interlocks.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X10B the Right Cylinder?
When sizing this ASE20X10B, compare it with the smaller ASE16X10 (78.4 N at 0.5 MPa) if your load is lighter, or step up to the ASE25X10 (210.1 N at 0.5 MPa) for more margin. The 10 mm stroke is short, so this unit suits compact clamping or ejection tasks, not long travel. Since the spring returns the rod, it does not hold a mid-stroke position on air loss; it simply retracts to home. This model has a male rod thread (B code) and no magnet, so sensor mounting is not possible unless you order the -S option.
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 ASE20X10B FAQ
The ASE20X10B delivers 127.4 N of push force 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 maximum is 1.0 MPa (145 psi). The proof pressure is 1.5 MPa (215 psi).
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it saves mounting space in tight areas. It has a fixed TPU bumper at both ends to absorb impact, and it accepts FA/FB, LB, CA/CB, CR, SDB, and FTC mounting brackets. This model has no magnet, so you cannot add sensors unless you order the -S version.
