About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X20B
This AirTAC ASE100X20B is a single acting push cylinder with spring return, delivering 3640.7 N of push force at 0.5 MPa and 5211.5 N at 0.7 MPa, net of the return spring. The 100 mm bore with a 20 mm stroke suits high-force applications in tight spaces, as the ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder. The male rod thread (B code) simplifies attachment, while the hard-anodized aluminium body and S45C hard-chrome rod resist wear.
For safe operation, plan for roughly 222 kg of vertical lift at 0.5 MPa (using a 0.6 factor of the push force), so you can match real part weights with confidence. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the minimum working pressure is 0.2 MPa, ensuring reliable spring return even at low supply. This cylinder operates on filtered air (40 um) at speeds of 50-500 mm/s, within a temperature range of -20 to +70 C.

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 ASE100X20B Is Used
Die Cutting Press
Use the ASE100X20B to drive a die-cutting head in a compact press, delivering 3640.7 N at 0.5 MPa to stamp gaskets or leather parts with a short 20 mm stroke.
Clamping Fixture
In an automated assembly line, this cylinder can clamp heavy workpieces (up to 222 kg vertical equivalent) against a stop, with the spring retracting the clamp when air is released.
Test Rig Actuator
For a laboratory test rig, apply a precise 3640.7 N force at 0.5 MPa to a specimen, using the compact body to fit within a guarded enclosure where a longer cylinder would not.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X20B the Right Cylinder?
When sizing, compare this 100 mm bore with the 80 mm bore, which delivers 2316.2 N at 0.5 MPa, to confirm you need the higher force class. The ASE100X20B is single acting, so it does not hold a mid-stroke position; on air loss, the spring retracts the rod fully. Choose this model for short-stroke, high-force pushes where space is limited, and pair it with FA/FB flange, LB foot, or CA/CB clevis mounts from the ISO 21287 family. Note that this unit has no magnet (no -S code), so CMSE or DMSE sensors cannot be fitted; order the -S option if you need position sensing.
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 ASE100X20B 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 proof pressure is 1.5 MPa (215 psi).
No, this model (ASE100X20B) has no magnet because the -S option was not ordered. To use CMSE or DMSE reed or solid-state switches, you must order the cylinder with the -S code to get the built-in magnet. The fixed TPU bumper at both ends handles end-of-stroke impact.
