Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X20S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X20S is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø100mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body.

About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X20S
This AirTAC ASE100X20S is a single acting push cylinder with spring return, extending its 20 mm rod when air is applied and retracting it via the built-in spring when pressure drops. Its 100 mm bore delivers a net push force of 3640.7 N at 0.5 MPa, already accounting for the spring resistance, so you can plan your application around this real output.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit into tight machine frames and guarding where a full-length unit won't. The optional -S magnet is fitted on this model, enabling CMSE or DMSE reed or solid-state switches for position sensing. For a safe working load, plan for about 2184 N (roughly 223 kg) of vertical lift at 0.5 MPa, using a 2:1 margin on 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 (Ø100mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 3640.7 N |
| 0.7 MPa | 5211.5 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 ASE100X20S Is Used
Press Fit Station
Use the ASE100X20S to press small bushings into housings on an assembly line, delivering 3640.7 N at 0.5 MPa to seat parts consistently without over-travel.
Clamping Fixture
Mount this cylinder on a jig to clamp sheet metal panels during welding, with the spring return releasing the part automatically when air is cut, speeding up cycle times.
Lift Gate Assist
In a packaging line, use the ASE100X20S to lift a light guard or flap, handling about 223 kg vertically at 0.5 MPa with a safety margin, and retracting it when not needed.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X20S the Right Cylinder?
When sizing, compare this 100 mm bore against a smaller 63 mm bore, which offers 1420.5 N at 0.5 MPa, to see if you need the extra capacity. The ASE100X20S is best for short-stroke pushes up to 20 mm, as single-acting cylinders have limited travel; for longer strokes, consider a double-acting ACE model. Since this unit has the -S magnet, you can add CMSE or DMSE sensors to confirm rod position, but remember the spring only returns the rod to its home position and does not hold a mid-stroke load. Mounting options like FA/FB flanges, LB foot brackets, or CA/CB clevises bolt directly to the ISO 21287 face, simplifying integration into existing fixtures.
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 ASE100X20S FAQ
At 0.5 MPa, the push force is 3640.7 N, and at 0.7 MPa it is 5211.5 N, both net of the return spring. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (28-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The ASE100X20S body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight spaces like machine guards or gantries. It uses a fixed TPU bumper at both ends to absorb impact, and the -S magnet allows CMSE or DMSE sensors to be mounted for position feedback.
