About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25
This AirTAC ASE63X25 is a single acting push cylinder with spring return, meaning air extends the rod and the built-in spring retracts it, needing only one air line. It delivers a net push of 1420.5 N at 0.5 MPa and 2044 N at 0.7 MPa, already accounting for the spring's resistance, so you can size it directly for your load.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, freeing space in tight machine frames and guarding. With a 63 mm bore, it suits medium-duty pushes; for a lighter option, the 50 mm bore gives 875.5 N, while the 80 mm bore steps up to 2316.2 N at 0.5 MPa. The hard-anodized aluminium body and S45C chrome-plated rod resist wear in repetitive cycles.

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 ASE63X25 Is Used
Jig Clamping
Use in a drilling jig to clamp a 60 mm thick steel plate with 1420.5 N push, holding it firmly during a 25 mm stroke cycle.
Carton Ejection
Eject a packed carton from a conveyor stop on a packaging line, using the spring return to reset quickly for the next box.
Guard Door Lift
Lift a light machine guard door about 25 mm for access, relying on the compact body to fit within the frame's limited space.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25 the Right Cylinder?
Choose this 63 mm bore when you need a compact, single-acting push with a spring return, typical for short-stroke clamping or ejection tasks. At 0.5 MPa, it pushes 1420.5 N, but plan for about 852 N of real work to keep a safety margin; vertically, it lifts roughly 87 kg with a 2:1 safety factor. For a smaller footprint, the 50 mm bore pushes 875.5 N, while the 80 mm bore offers 2316.2 N if you need more force. The spring returns the rod to its home position on air loss, so it does not hold mid-stroke positions. Mount with FA/FB flange, LB foot, CA/CB clevis, or SDB pivot brackets, and order the optional -S code if you need a magnet for CMSE or DMSE sensors.
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 ASE63X25 FAQ
The ASE63X25 is single acting push with spring return, delivering 1420.5 N at 0.5 MPa and 2044 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 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight spaces like jigs or guards. It uses a fixed TPU bumper at both ends for energy absorption, and you can mount it with FA/FB flange, LB foot, or CA/CB clevis brackets. The optional -S magnet enables CMSE or DMSE sensors, but it is not standard.
