Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20SB 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 ASE80X20SB
This ASE80X20SB 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. With an 80 mm bore it delivers 2316.2 N of push force at 0.5 MPa, already net of the spring, and needs a minimum of 0.2 MPa to overcome the spring and start moving.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into tight machine guarding and tooling spaces. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and the fixed TPU bumper at both ends absorbs end-of-stroke impact. The optional -S magnet is fitted on this model, so it can work with CMSE or DMSE reed and solid-state switches for position sensing.

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 ASE80X20SB Is Used
Jig Clamping
Use the 2316.2 N push at 0.5 MPa to clamp a workpiece in a CNC fixture, with the spring retracting the clamp when the cycle ends.
Carton Press
In a packaging line, this cylinder presses down on a carton flap to fold it before sealing, and the spring lifts the press clear after each cycle.
Guard Door Lock
Mount it on a machine guard to push a locking pin into place, keeping the guard closed during operation, with the spring releasing it when air is off.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20SB the Right Cylinder?
For a lighter duty, the ASE63X25 offers 1420.5 N at 0.5 MPa, while this ASE80X20SB steps up to 2316.2 N for heavier clamping or pressing tasks. Since it is single acting, the spring returns the rod to its home position on air loss, but it does not hold a mid-stroke position, so plan for applications that need a retracted rest state. The male rod thread (B code) simplifies mounting of custom tooling, and the 1/4" port suits standard shop air lines.
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 ASE80X20SB FAQ
At 0.5 MPa the push force is 2316.2 N, and at 0.7 MPa it rises to 3321.5 N. These values are net of the return spring, so they are the usable force at the rod. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in compact machine frames and behind guards where a longer cylinder would not. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet on this model allows CMSE or DMSE switches to sense the rod position.
