About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X20
The ASE63X20 is a genuine AirTAC ISO 21287 compact cylinder, single acting with spring return, so air extends the rod and the internal spring retracts it. 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 medium-duty push applications.
Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which lets it fit into tight machine guards and compact jigs. For a safe working load, plan on using about 852 N (roughly 87 kg) of vertical lift capacity at 0.5 MPa, not the full rating, to account for real-world friction and speed. The optional -S magnet enables CMSE or DMSE sensors, but this unit without the S code has no magnet fitted.

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 (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 ASE63X20 Is Used
Jig Clamping
Use the ASE63X20 to clamp workpieces in a CNC fixture where space is limited. Its 1420.5 N push at 0.5 MPa holds parts firmly during drilling, and the spring return clears the clamp when air is removed.
Sorting Gate
In a packaging line, this cylinder can actuate a diverter gate to route boxes to different lanes. The 20 mm stroke is enough to move the gate, and the compact body fits under the conveyor frame.
Press Guard Interlock
Mount the ASE63X20 on a small press guard to push a locking pin into place. The 2044 N push at 0.7 MPa ensures the guard stays closed during operation, and the spring retracts the pin when the cycle ends.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X20 the Right Cylinder?
When sizing, compare the ASE63X20 against the ASE50X20, which pushes 875.5 N at 0.5 MPa, and the ASE80X20, which pushes 2316.2 N at the same pressure. If your application needs more force, step up to the 80 mm bore; if space is tighter and force is lower, the 50 mm bore may suffice. Remember this is single acting, so it only pushes; the spring returns the rod, and it does not hold a mid-stroke position on air loss. Choose the optional -S code if you need position sensing, and select from FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets to match your mounting.
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 ASE63X20 FAQ
The ASE63X20 delivers 1420.5 N push at 0.5 MPa and 2044 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi). Operating pressure range is 0.2-1.0 MPa (28-145 psi).
Yes, it is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder. It has a fixed TPU bumper at both ends to absorb impact, and it accepts standard ISO 21287 mounting brackets like FA/FB flange, LB foot, or CA/CB clevis. The optional -S magnet is required for CMSE or DMSE sensors.
