About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25SB
The ASE63X25SB is a single acting push cylinder with spring return, extending its 16 mm rod with air and retracting it via an internal spring. It delivers 1420.5 N of push force at 0.5 MPa (net of the spring), making it a strong choice for compact automation tasks.
Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight machine guards and gantries. With the optional -S magnet fitted, it works with CMSE or DMSE switches for position sensing. For a safe working load, plan for about 852 N (0.6 times the 0.5 MPa force) of real work, which lifts roughly 87 kg vertically with a 2:1 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 (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 ASE63X25SB Is Used
Jig Clamping
Use in a CNC fixture to clamp a 63 mm bore workpiece holder with 1420.5 N force, ensuring stable machining without bulky cylinders.
Carton Ejection
In a packaging line, this cylinder pushes filled cartons off a conveyor at 50-500 mm/s, with the spring retracting the rod for the next cycle.
Guard Door Actuation
Mount on a machine guard door to push it open with 2044 N at 0.7 MPa, using the compact body to fit within safety enclosure frames.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25SB the Right Cylinder?
For lighter duty, the ASE50X25 offers 875.5 N at 0.5 MPa, while the ASE80X25 provides 2316.2 N for heavier tasks. Since this is single acting, the spring returns the rod to its home position on air loss; it does not hold a mid-stroke position. Choose the male rod thread (B) for direct coupling, and mount with FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets.
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 ASE63X25SB FAQ
At 0.5 MPa, the push force 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 maximum is 1.0 MPa (28-145 psi).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, ideal for tight spaces. It has a fixed TPU bumper at both ends to absorb impact, and with the -S magnet, you can add CMSE or DMSE sensors for position feedback.
