Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30 is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø63mm bore and 30mm 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 ASQ63X30
The AirTAC ASQ63X30 is a single-acting push-type JIS compact cylinder. Supplying air to the single PT1/4 port extends the Ø20 mm rod, while an internal mechanical spring retracts it upon exhaust. This design requires only one pneumatic line, simplifying valve plumbing and saving manifold space. The unit operates within a 0.2-1.0 MPa range, needing at least 0.2 MPa to overcome the return spring.
At 0.5 MPa, the theoretical push force (before spring) is 1558.6 N, reaching 2182 N at 0.7 MPa. Because the internal spring consumes energy during retraction, the net usable output is lower than these theoretical figures; always verify the exact net force from the official datasheet. End-of-travel deceleration relies on a fixed NBR elastomer bumper, which is not adjustable. For high kinetic energy loads, consider adding an external shock absorber to prevent premature wear.

| 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 ASQ63X30 Is Used
Injection Mold Ejection
Pushes finished plastic parts out of injection molds using a short, powerful 30 mm stroke, relying on the internal spring to retract the pin safely when air pressure drops.
Carton Flap Folding
Drives short-stroke folding arms on automated packaging lines to close corrugated box flaps, where the single-acting return ensures predictable reset between cycles.
Heavy-Duty Part Hold-Down
Secures heavy metal castings or plates on CNC machining centers during milling, utilizing the 63 mm bore's substantial theoretical push force for rigid clamping.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30 the Right Cylinder?
If 1558.6 N of theoretical push at 0.5 MPa is insufficient, there is no larger bore in the ASQ family as 63 mm is the maximum size offered. If your application requires less force, stepping down to the ASQ50X30 provides 981.8 N of theoretical push at 0.5 MPa. Both options share the 30 mm maximum stroke limit for this frame size. Should your mechanism require a longer travel distance than 30 mm, you must switch to the double-acting ACQ series instead of this spring-return unit. When ordering, confirm the 63 mm bore, 30 mm stroke, default female M10x1.5 rod-end thread, and note that this specific configuration ships without a magnet.
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 ASQ63X30 FAQ
The theoretical push force (before spring) is 1558.6 N at 0.5 MPa and 2182 N at 0.7 MPa. Because an internal spring returns the rod, the net usable force is lower; verify the exact net figure from the datasheet. Operating pressure is 0.2-1.0 MPa, requiring a 0.2 MPa minimum to overcome the spring. The maximum stroke is 30 mm.
Deceleration at the stroke ends relies on a fixed NBR elastomer bumper that is permanently built into the body and cannot be adjusted. If your moving mass is high, you should slow the approach speed or mount an external shock absorber. If air loss occurs, the internal spring provides a fail-safe return, pulling the rod back to its retracted rest position.
