Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25 is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø63mm bore and 25mm stroke. Air pushes the rod and an internal spring performs the opposite stroke, so one solenoid line drives the motion — ideal for short-stroke clamping and ejection in tight spaces.

About the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25
The AirTAC ASQ63X25 is a single-acting push-type JIS compact cylinder featuring a 63mm bore and 25mm stroke. Feeding compressed air to the single PT1/4 port extends the rod, while an internal mechanical spring handles retraction. This design requires only one air line, cutting plumbing complexity. The body incorporates fixed NBR elastomer bumpers to manage end-of-stroke impact rather than relying on adjustable air cushions.
Delivering a theoretical push force of 1558.6N at 0.5 MPa and 2182N at 0.7 MPa, this model provides substantial extension power. Remember that the return spring absorbs some of this energy, so the actual net output is lower and should be verified against the official datasheet. Operating pressure must be at least 0.2 MPa to overcome the spring. This unit ships without a magnet, though the barrel retains sensor grooves for adding a switch later.

| Acting type | Single acting, push type |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 500 mm/s |
| Cushion | Bumper |
| Max standard stroke | Up to 30 mm |
Specifications follow the official AirTAC ACQ-family datasheet. Single-acting types start at 0.2 MPa (the spring must be overcome). Confirm against the product label before installation.
Theoretical Output Force (Ø63mm, Push)
| Pressure | Push force (before spring) |
|---|---|
| 0.5 MPa | 1559 N |
| 0.7 MPa | 2182 N |
These are theoretical air-side forces; the return-spring force reduces the NET usable output. Single-acting push only — the spring performs the opposite stroke. Confirm the net figure from the datasheet and size with a safety margin.

Where the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25 Is Used
Heavy-Duty Part Ejection
Pushes heavy machined metal components out of CNC milling centers using the 1558.6N theoretical extension force, with the spring ensuring the arm retracts safely away from the workspace.
Corrugated Box Flap Hold-Down
Maintains downward pressure on large packaging box flaps during automated tape sealing, relying on the fixed NBR bumper to absorb the repetitive impact without damaging the carton surface.
Press Die Pin Locating
Extends a 20mm diameter locating pin to align heavy sheet metal blanks in a mechanical press, utilizing the fail-safe spring return to pull the pin back before the die closes.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25 the Right Cylinder?
For sizing, the 63mm bore offers the highest push capacity in this range. If your application requires less force, the next size down is the 50mm bore providing 981.8N theoretical push at 0.5 MPa. Since 63mm is the largest available ASQ diameter, moving up in force would require a different cylinder family entirely. The 25mm stroke is well within the 30mm maximum limit for this bore. If your machine needs longer travel than 30mm, you must switch to a double-acting ACQ compact cylinder. When ordering, verify your requirements for the 63mm bore, 25mm stroke, female M10x1.5 rod thread, and whether you need the -S magnet option for position sensing.
Quick checklist
- ✓ Net push force (after spring) at your pressure
- ✓ Stroke ≤ 30 mm (single-acting limit)
- ✓ Single air line saves a valve/port
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Remember the spring performs the return stroke.
- check Avoid side load on the short piston rod.
- check Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25 FAQ
The theoretical push force before spring resistance is 1558.6N at 0.5 MPa and 2182N at 0.7 MPa. The internal return spring lowers the net usable output, so confirm the exact net figure from the datasheet. Because it is single-acting, a minimum operating pressure of 0.2 MPa is required to overcome the spring, and the maximum standard stroke is 30mm.
Instead of an adjustable air cushion, it uses a fixed NBR elastomer bumper at the ends to absorb impact. For high-speed or high-energy loads, you should add an external shock absorber. Additionally, this specific model does not include a magnet, but the body features sensor grooves allowing you to mount reed or solid-state switches if you install a magnet-equipped version.
