Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5S
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5S is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø63mm bore and 5mm 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 ASQ63X5S
The AirTAC ASQ63X5S is a 63mm bore, single-acting push-type compact cylinder. Supplying air to the single PT1/4 port extends the rod, while an internal mechanical spring handles the retraction. This design requires only one solenoid valve line, simplifying your pneumatics plumbing. It delivers 1558.6N of theoretical push force at 0.5 MPa (2182N at 0.7 MPa) before accounting for the spring. Keep in mind the return spring lowers the net usable output, so confirm the final net figure from the official datasheet.
Featuring a 5mm stroke and a 20mm piston rod, this JIS compact unit uses a fixed NBR elastomer bumper at the endcaps for end-of-stroke impact absorption rather than an adjustable air cushion. The -S suffix indicates a built-in piston magnet, enabling position detection via compatible reed or solid-state electronic switches. If air pressure drops, the fail-safe spring immediately pulls the rod back to its retracted rest position, ensuring a predictable default state.
Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5S Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5S |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø63 mm |
| Stroke | 5 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 ASQ63X5S Is Used
Heavy-Duty Part Clamping
Applies high holding force to secure heavy metal castings during CNC machining operations.
Stamping Ejection
Pushes finished stamped components out of a heavy-duty mechanical press bed.
Fixture Hold-Down
Locks large automotive sub-assemblies into welding fixtures on a production line.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5S the Right Cylinder?
For a 63mm bore, the theoretical push force is 1558.6N at 0.5 MPa. If your application requires less force, the next size down is the 50mm bore (981.8N at 0.5 MPa); as the largest available ASQ option, there is no larger bore. This 5mm stroke is well within the 30mm maximum travel limit for this bore size. If your mechanism needs a longer extension than 30mm, you must switch to the double-acting ACQ series. When ordering, verify your required 63mm bore, 5mm stroke, the -S magnet option, and whether you need the default female M10x1.5 or optional male M18x1.5 rod-end threads.
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 ASQ63X5S FAQ
The theoretical push force is 1558.6N at 0.5 MPa and 2182N at 0.7 MPa. Because it is spring-return single-acting, the internal spring reduces the net usable output, and a minimum operating pressure of 0.2 MPa is required to overcome the spring. The maximum stroke for this 63mm bore is 30mm.
It uses a fixed NBR elastomer bumper at the ends to absorb impact energy, rather than an adjustable air cushion. For high-speed or high-energy loads, consider adding an external shock absorber. The -S magnet option allows position detection using reed or solid-state electronic switches.
