About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X20S
This AirTAC ASE63X20S is a single acting push cylinder with spring return, so air extends the rod and the built-in spring retracts it, needing only one air line. At 0.5 MPa it delivers 1420.5 N of push force net of the spring, and at 0.7 MPa that rises to 2044 N, making it a strong choice for compact automation.
Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which helps it fit into tight jigs and guarded cells. The optional -S magnet is fitted on this model, so CMSE or DMSE switches can be mounted for position sensing, and the fixed TPU bumper at both ends absorbs end-of-stroke energy without any adjustment.

Theoretical Output Force (Ø63mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 1420.5 N |
| 0.7 MPa | 2044.0 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 ASE63X20S Is Used
Jig Clamping
Use the 1420.5 N push at 0.5 MPa to clamp a workpiece in a CNC fixture, with the spring retracting the rod when air is released.
Carton Ejection
In a packaging line, this cylinder can push a filled carton off a conveyor onto a chute, using its 20 mm stroke for a quick, compact motion.
Guard Door Stop
Mount it on a machine guard to push a latch into place, where the short body fits within the frame and the spring ensures retraction when the air is off.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X20S the Right Cylinder?
When sizing, compare this 63 mm bore to the 50 mm bore, which pushes 875.5 N at 0.5 MPa, or the 80 mm bore at 2316.2 N, to match your load. Since this is single acting, the spring returns the rod to its retracted home position on air loss, so it does not hold a mid-stroke position. The 1/8" port suits standard fittings, and the female M10x1.5 rod thread accepts common attachments.
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 ASE63X20S FAQ
The push force at 0.5 MPa is 1420.5 N and at 0.7 MPa it is 2044 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 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight spaces. It has a fixed TPU bumper at both ends for energy absorption, and the optional -S magnet on this model allows CMSE or DMSE switches for sensing.
