Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20B 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 ASE80X20B
This AirTAC ASE80X20B is a single acting push cylinder with spring return, so air extends the 20 mm stroke rod and the built-in spring pulls it back when pressure drops. 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, making it a strong choice for compact automation cells.
The ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits inside tight machine guards and gantries where a full-length unit will not. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and the fixed TPU bumper at each end softens the stop. For a safe working load, plan on about 1390 N of real work at 0.5 MPa, which is roughly 142 kg of vertical lift 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 ASE80X20B Is Used
Jig Clamping
Use the 2316.2 N push at 0.5 MPa to clamp a sheet metal fixture in a stamping press, where the short body fits between the die and the guard.
Packaging Stop
Mount this cylinder on a conveyor line to push a carton into a chute; the 20 mm stroke is enough to nudge the box, and the spring returns it for the next cycle.
Test Rig Actuator
In a laboratory test bench, use the ASE80X20B to apply a repeatable 2316.2 N force to a component, with the TPU bumper preventing shock at the end of the stroke.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X20B the Right Cylinder?
When sizing this ASE80X20B, compare it with the ASE63X25, which pushes 1420.5 N at 0.5 MPa, or step up to the ASE100X25 at 3640.7 N if you need more force. The 20 mm stroke is short, so this unit suits quick indexing or clamping motions rather than long travel. Since the spring retracts the rod, it returns to home on air loss but does not hold a mid-stroke position. The male rod thread (B code) simplifies mounting to a clevis or rod end, and the 1/4" port matches standard shop air lines. This model has no magnet, so order the -S option if you need CMSE or DMSE sensor feedback.
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 ASE80X20B 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 operating pressure range is 0.2-1.0 MPa (28-145 psi), with a speed range of 50-500 mm/s.
Yes, the ASE80X20B is an ISO 21287 compact cylinder, with a body about 50% shorter than an ISO 15552 profile cylinder. It has a fixed TPU bumper at both ends for shock absorption. The male rod thread (B code) allows direct connection to rod knuckles, and mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets.
