Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X25S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X25S is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø100mm bore and 25mm stroke, 1/4" air ports and a hard-anodized aluminium body.

About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X25S
This AirTAC ASE100X25S is a single acting push cylinder with spring return, meaning air extends the rod and an internal spring pulls it back when pressure drops. At 0.5 MPa it delivers 3640.7 N of push force, net of the spring, so you can plan real work around that figure rather than a theoretical rating.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which helps it fit inside tight guarding or under a press platen where a full-length unit would not. The optional -S magnet is fitted here, so CMSE or DMSE reed and solid-state switches can mount directly to sense the piston position. For a safe working load, plan for about 2184 N of actual work at 0.5 MPa, which lifts roughly 223 kg vertically with a 2:1 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 (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 ASE100X25S Is Used
Press platen return
In a small stamping press, this ASE100X25S pushes a platen down with 3640.7 N at 0.5 MPa and the spring lifts it back, freeing the operator's hands between cycles.
Carton ejector
On a packaging line, this cylinder pushes a filled carton off a conveyor onto a chute. The 25 mm stroke is enough to clear the edge, and the spring retracts the rod for the next box.
Fixture clamp assist
In a welding jig, this unit applies a firm 3640.7 N push to hold a bracket in place during tack welding, then springs back so the part can be removed quickly.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X25S the Right Cylinder?
Choose this ASE100X25S when you need a compact, single-acting push with a 25 mm stroke and a 100 mm bore. It suits applications where the return spring does the retracting and you only need one air line, simplifying the circuit. If your load is lighter, consider the ASE63X25S with 1420.5 N at 0.5 MPa; for heavier pushes, this 100 mm bore is the largest in the ASE family, so confirm the force requirement against the 3640.7 N figure before ordering. The spring retracts the rod to home on air loss, so it does not hold a mid-stroke position; use a separate brake or lock if that is needed. The 1/4" port and female M12x1.75 rod thread are standard, and the -S magnet allows sensor feedback for automation.
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 ASE100X25S FAQ
At 0.5 MPa, the push force is 3640.7 N; at 0.7 MPa, it is 5211.5 N. These values are net of the return spring, so they are the usable forces 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, so it fits in confined areas like machine guards or under a worktable. It has a fixed TPU bumper at both ends to absorb end-of-stroke impact, which is not adjustable but provides reliable deceleration for the 50-500 mm/s speed range.
