Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20 is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø80mm bore and 20mm 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 ASE80X20
This ASE80X20 is a single acting push cylinder with spring return, meaning air extends the rod and a built-in spring retracts it, so it needs only one air line and returns to home on air loss. At 0.5 MPa it delivers 2316.2 N of push force (net of the spring), and at 0.7 MPa that rises to 3321.5 N, so it suits heavy clamping or pressing tasks in tight spaces.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit inside guards or gantries where a full-length unit will not. For real work, plan for about 1390 N at 0.5 MPa rather than the full rating, and it can lift about 142 kg vertically with a 2:1 safety margin. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the hard-anodized aluminium body with S45C hard-chrome rod resists wear in dirty shop air.

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 ASE80X20 Is Used
Jig Clamping
Use this ASE80X20 to clamp a workpiece against a fixed stop in a CNC fixture. The 2316.2 N push at 0.5 MPa holds parts firmly during drilling or milling, and the spring returns the clamp clear for loading.
Carton Pressing
In a packaging line, this cylinder presses folded cartons flat before taping. Its 20 mm stroke is enough to compress the board, and the compact body fits between conveyor rails where longer cylinders would not.
Guard Door Lock
Mount this unit on a machine guard to push a locking pin into a receiver. The spring retracts the pin when air is removed, so the guard opens automatically on power loss, and the 3321.5 N at 0.7 MPa resists forced opening.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20 the Right Cylinder?
Choose this 80 mm bore when you need a compact, single-acting push with spring return and a short 20 mm stroke. It delivers 2316.2 N at 0.5 MPa, which is roughly 2.6 times the 875.5 N of a 50 mm bore unit, so it handles heavier loads without taking up extra mounting length. Since it is single acting, the spring retracts the rod and it does not hold a mid-stroke position on air loss - it returns to the retracted home position.
Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, plus I and Y rod knuckles, all fitting the ISO 21287 face. This model has no magnet fitted, so no CMSE or DMSE sensor can be used unless you order the optional -S code. The port is 1/4" PT, and the rod end is female M12x1.75.
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 ASE80X20 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). The rod is 20 mm, the port is 1/4", and the female rod thread is M12x1.75.
The ASE80X20 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits inside machine guards, gantries, and compact jigs. It has a fixed TPU bumper at both ends to absorb end-of-stroke impact, and mounting brackets like FA/FB flange, LB foot, and CA/CB clevis bolt directly to the ISO 21287 face. Note that this model has no magnet, so you need the optional -S code to use CMSE or DMSE sensors.
