Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25S
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25S 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 ASQ63X25S
The AirTAC ASQ63X25S is a 63mm bore JIS compact cylinder configured for single-acting push operation. Supplying air to the single PT1/4 port extends the Ø20mm rod, while an internal mechanical spring automatically retracts it upon exhaust. This design requires just one solenoid valve line, simplifying your pneumatics plumbing. It delivers a substantial 1558.6N theoretical push at 0.5 MPa (2182N at 0.7 MPa) before spring deduction.
Because the return mechanism occupies internal length, the stroke is capped at 30mm for this bore size, making this 25mm unit well-suited for short, high-power motions. The internal return spring lowers the actual net output force, so verify the usable thrust from the official datasheet. An NBR elastomer bumper fixed inside the body manages end-of-stroke impact, and the included -S piston magnet enables position detection via reed or solid-state switches installed directly into the body grooves. If pneumatic supply drops, the spring guarantees a fail-safe retraction to the resting state.
Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25S Technical Specifications

| Bore size | Ø63 mm |
| Stroke | 25 mm |
| 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 ASQ63X25S Is Used
Heavy-Duty Stamping Pin
Provides the robust 63mm bore thrust needed to drive a marking pin into thick gauge steel plates within an automated fabrication cell.
Injection Mold Ejection
Uses the 25mm stroke and spring-return mechanism to positively push finished plastic components out of heavy injection tooling upon air exhaust.
Pallet Carton Platen
Applies high clamping pressure to hold large corrugated shipping cartons stationary on a palletizing conveyor during automated banding.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25S the Right Cylinder?
For sizing context within the 12-63mm ASQ range: dropping down to the 50mm bore drops the 0.5 MPa theoretical push to 981.8N, while 63mm is the largest available bore offering the maximum 1558.6N theoretical capacity. If your application requires a stroke longer than the 30mm maximum allowed here, you must switch to the double-acting ACQ series. When finalizing your order, verify the 63mm bore, 25mm stroke, the -S magnet option for sensors, and the default female M10x1.5 rod-end thread.
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 ASQ63X25S FAQ
It provides a theoretical push of 1558.6N at 0.5 MPa and 2182N at 0.7 MPa before the return spring is factored in; the spring lowers net output so confirm exact figures via the datasheet. Operating pressure is 0.2-1.0 MPa, with a 0.2 MPa floor required to overcome the spring. The maximum stroke for a 63mm bore is 30mm.
It relies on a fixed NBR elastomer bumper at the end of travel to absorb impact—it is not an adjustable air cushion, so for high-energy cycles you may need an external shock absorber. The -S option includes a piston magnet that works with both reed and electronic solid-state switches fitted into the body grooves for precise end-position verification.
