About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X20
This AirTAC ASE20X20 is a single acting compact cylinder, with air extending the rod and a return spring retracting it. It delivers a net push force of 127.4 N at 0.5 MPa, and 190.2 N at 0.7 MPa, already accounting for the spring. The ISO 21287 short body takes up roughly half the mounting length of an ISO 15552 profile cylinder, making it a fit for tight fixtures. For a safe working load, plan around 76 N at 0.5 MPa, which translates to lifting about 7.8 kg vertically with a 2:1 margin. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the hard-anodized aluminium body with S45C hard-chrome rod ensures durability. The minimum working pressure is 0.2 MPa to overcome the spring, and the port is M5x0.8 for this 20 mm bore.
The optional -S magnet is not fitted in this standard version, so no CMSE or DMSE sensor can be mounted without ordering that code. This cylinder operates on filtered air (40 um) within 0.2-1.0 MPa (28-145 psi), at speeds of 50-500 mm/s, and in temperatures from -20 to +70 C. The rod end has a female M6x1.0 thread, and the port is PT. With a 20 mm stroke, it suits short, repetitive motions where space is limited, and the spring return ensures the rod retracts on air loss, though it does not hold a mid-stroke position.

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 (Ø20mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 127.4 N |
| 0.7 MPa | 190.2 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 ASE20X20 Is Used
Tight Jig Clamping
Use in a fixture that clamps small parts on a CNC machine, where the 20 mm stroke and 127.4 N force at 0.5 MPa provide enough push to hold a component without taking up much space.
Light Packaging Ejector
In a packaging line, this cylinder can eject a small carton or label from a guide, with the spring return quickly resetting for the next cycle at speeds up to 500 mm/s.
Guard Door Pusher
Mount on a machine guard to push a safety door closed, using the compact body to fit within the guard frame and the spring return to retract when air is removed.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE20X20 the Right Cylinder?
When sizing this ASE20X20, compare it with the smaller ASE16X20, which offers 78.4 N at 0.5 MPa, or the larger ASE25X20, which delivers 210.1 N at 0.5 MPa. The 20 mm bore provides a middle ground for light to medium loads, but remember the spring return does not hold a load in position; it only retracts the rod on air loss. For mounting, choose from FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets, all compatible with the ISO 21287 face. If you need position sensing, order the -S option to include the magnet for CMSE or DMSE switches; without it, no sensor can be used. The stroke is limited to 25 mm for this bore, so ensure your application fits within that range.
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 ASE20X20 FAQ
The ASE20X20 delivers a push force of 127.4 N at 0.5 MPa and 190.2 N at 0.7 MPa, 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 ISO 21287 short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits in tight spaces like jigs or guards. The fixed TPU bumper at both ends absorbs impact, and mounting options like FA/FB flange or LB foot bolt directly to the standard face.
