Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20S 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 ASE80X20S
This AirTAC ASE80X20S is a SINGLE-ACTING PUSH cylinder with spring return, so air extends the rod and the built-in spring pulls it back when pressure drops. It delivers 2316.2 N of push force at 0.5 MPa (net of the spring), which is enough for moderate clamping or lifting tasks in tight spaces.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for fitting inside machine guards or compact jigs. The optional -S magnet is included here, so you can mount CMSE or DMSE reed or solid-state switches for position sensing. As a rule of thumb, plan for about 1390 N of real work at 0.5 MPa, which translates to lifting about 142 kg vertically with a 2:1 safety 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 (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 ASE80X20S Is Used
Jig Clamping
Use in a CNC fixture to clamp a workpiece with 2316.2 N at 0.5 MPa, holding parts securely during milling or drilling in a compact space.
Light Press Operation
Drive a small press or stamping die that needs a consistent push force, such as embossing labels or forming thin metal parts, with the spring returning the ram.
Gate Actuator
Operate a safety gate or access door on packaging machinery, where the spring retracts the rod to keep the gate closed when air is off.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20S the Right Cylinder?
When sizing, compare this 80 mm bore with the 63 mm bore, which offers 1420.5 N at 0.5 MPa, or the 100 mm bore at 3640.7 N. Choose 80 mm if you need a balance of force and compactness. Since it is single acting, the spring always returns the rod to the retracted position on air loss, so it does not hold a mid-stroke load. The 1/4" port suits standard air lines, and the optional -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 ASE80X20S FAQ
The push force is 2316.2 N at 0.5 MPa and 3321.5 N at 0.7 MPa, 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).
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits inside machine guards or compact fixtures. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
