Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X25B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X25B is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø80mm bore and 25mm stroke, 1/4" 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 ASE80X25B
This AirTAC ASE80X25B is a single acting push cylinder with spring return, delivering 2316.2 N of push force at 0.5 MPa (net of the return spring). Its ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine guards and compact jigs where a full-length cylinder would not. The hard-anodized aluminium body and S45C hard-chrome rod resist wear in dirty shop air.
For real work, plan on roughly 1390 N usable force at 0.5 MPa, which lifts about 142 kg vertically with a 2:1 safety margin. The male rod thread (B code) simplifies mounting with rod clevis or knuckle accessories. Minimum working pressure is 0.2 MPa to overcome the return spring, and the fixed TPU bumper absorbs end-of-stroke impact.

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 (Ø80mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 2316.2 N |
| 0.7 MPa | 3321.5 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 ASE80X25B Is Used
Compact Clamping Fixture
Use in a CNC machining fixture to clamp a 100 kg workpiece against a stop, with the 2316.2 N push at 0.5 MPa providing secure holding during drilling or milling.
Carton Ejection
In a packaging line, this cylinder pushes filled cartons off a conveyor onto a chute. The 25 mm stroke suits short ejection distances, and the compact body fits under the conveyor frame.
Press Guard Interlock
Mount on a small press guard to push a safety latch into place. The spring return retracts the rod when air is off, ensuring the guard stays closed, and the TPU bumper reduces noise at high cycle rates.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X25B the Right Cylinder?
Choose this 80 mm bore when you need a compact single acting cylinder with a strong push, such as clamping or pressing in tight spaces. Compare with the 63 mm bore, which pushes 1420.5 N at 0.5 MPa, or the 100 mm bore at 3640.7 N, to match your load. Since it is single acting, the spring retracts the rod on air loss, so it does not hold a mid-stroke position. The male rod thread (B) suits direct linkage; order the optional -S magnet if you need CMSE or DMSE sensors, but this model has no magnet.
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 ASE80X25B FAQ
At 0.5 MPa, the push force is 2316.2 N, and at 0.7 MPa it is 3321.5 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). Operating pressure range is 0.2-1.0 MPa (28-145 psi).
Yes, it is an ISO 21287 compact cylinder, about 50% shorter than an ISO 15552 profile cylinder. It mounts with FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets. The male rod thread (B) is M12x1.75, and the port is 1/4" PT.
