Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X20
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X20 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 ASE100X20
This AirTAC ASE100X20 is a single acting push cylinder with spring return, meaning air extends the rod and a built-in spring retracts it. It delivers a net push force of 3640.7 N at 0.5 MPa and 5211.5 N at 0.7 MPa, already accounting for the return spring, so you can size it directly for your application.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight machine frames. At 0.5 MPa, a practical safe working load is about 2184 N, which translates to lifting roughly 223 kg vertically with a 2:1 safety margin. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and a fixed TPU bumper at both ends absorbs end-of-stroke impact.

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 ASE100X20 Is Used
Heavy Press Clamp
Use the 3640.7 N push at 0.5 MPa to clamp thick metal sheets in a stamping press fixture, where the short body fits under a guard and the spring retract clears the part quickly.
Pallet Stop
In a conveyor system, this cylinder can extend a stop to hold a loaded pallet weighing up to 223 kg with a 2:1 margin, then retract via spring to let it pass.
Die Ejector
Mount it in a molding machine to push out a finished plastic part from a die cavity; the 20 mm stroke is enough for small parts, and the TPU bumper prevents damage at full extension.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X20 the Right Cylinder?
For lighter pushing tasks, the ASE80X20 offers 2316.2 N at 0.5 MPa, while this ASE100X20 provides 3640.7 N for heavier work. Since it is single acting, the spring retracts the rod on air loss, returning it to the home position, but it does not hold a mid-stroke position. Choose the optional -S code to add a magnet for CMSE or DMSE sensors; without it, no sensor can be mounted. 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 ASE100X20 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). Proof pressure is 1.5 MPa (215 psi), and operating temperature ranges from -20 to +70 C.
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits into tight jigs or under guards where space is limited. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the optional -S magnet enables CMSE or DMSE sensors for position detection.
