Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30S
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30S 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 ASQ63X30S
The AirTAC ASQ63X30S is a 63 mm bore JIS compact cylinder configured for single-acting push operation. Supplying air to the single PT1/4 port extends the rod, while an internal mechanical spring handles retraction. This design requires a minimum of 0.2 MPa operating pressure to overcome the return mechanism. The theoretical push force is 1558.6 N at 0.5 MPa and 2182 N at 0.7 MPa. Keep in mind these are pre-spring figures; the internal spring lowers the net output, so verify the exact net force in the official datasheet.
This model includes a built-in piston magnet (-S) compatible with reed or solid-state electronic switches for position sensing. Travel is capped at 30 mm due to the internal spring length. It relies on a fixed NBR elastomer bumper at the end caps for impact absorption rather than an adjustable air cushion. If air pressure drops, the spring automatically forces the rod back to its rest position, providing a fail-safe retract action.

| Bore size | Ø63 mm |
| Stroke | 30 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 ASQ63X30S Is Used
Injection Molding Ejector
Uses the 1558.6 N theoretical push to positively eject heavy molded plastic parts from a press bed before the robotic arm extracts them.
Pallet Flap Folder
Deploys the rod to fold corrugated cardboard flaps on high-speed packaging lines, relying on the spring to quickly retract and clear the path.
Heavy-Duty Part Hold-Down
Applies firm downward clamping pressure on metal workpieces during CNC machining, ensuring the part stays fixed while the table moves.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30S the Right Cylinder?
For sizing context, stepping down to a 50 mm bore drops the theoretical push at 0.5 MPa to 981.8 N, while this 63 mm unit provides 1558.6 N. Because 63 mm is the largest available ASQ bore, you must add external mechanical leverage if more force is needed. If your automation requires a stroke beyond 30 mm, switch to the double-acting ACQ series. To order this single-acting compact actuator correctly, confirm the 63 mm bore, 30 mm stroke, the -S magnet option, 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 ASQ63X30S 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 retracts the rod, the net usable force is lower and must be confirmed via the datasheet. A minimum operating pressure of 0.2 MPa is required to overcome the spring, and the maximum stroke is capped at 30 mm.
Instead of an adjustable air cushion, it uses a fixed NBR elastomer bumper at the ends to absorb impact. For automation feedback, the -S option provides a built-in piston magnet that works with both reed and solid-state electronic switches. If air is lost, the spring ensures a fail-safe return to the retracted rest position.
