Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5 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 ASQ63X5
The AirTAC ASQ63X5 is a 63mm bore JIS compact cylinder engineered for single-acting push operation. Supplying air to the single PT1/4 port extends the Ø20mm rod, while an internal mechanical spring handles retraction. This design requires just one air line, simplifying plumbing and valve requirements. At 0.5 MPa, it generates a theoretical push force of 1558.6 N (2182 N at 0.7 MPa) before spring deduction; verify the net output via the datasheet for your specific load.
This 5mm stroke model is built for short, high-force movements within a riveted body. It relies on a fixed NBR elastomer bumper at the stroke ends rather than an adjustable air cushion. Because it lacks the -S suffix, the piston ships without a magnet, though the body retains standard switch grooves for future sensing upgrades. Should air pressure drop below the 0.2 MPa minimum or be lost entirely, the spring ensures a fail-safe return to the retracted rest position.

| 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 ASQ63X5 Is Used
Short-Stroke Stamping
Provides brief high-force stamping or marking actions on metal components within automated machining centers.
Heavy Part Ejection
Ejects dense molded parts from press cavities using a rapid 5mm extension before spring retraction resets the rod.
Brake Actuation
Drives a short clamping brake against rotating spindles in packaging equipment, utilizing the fail-safe spring return.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5 the Right Cylinder?
Selecting this 63mm bore actuator involves comparing its 1558.6 N theoretical push at 0.5 MPa against your actual load requirements. If your application requires less force, stepping down to the 50mm bore yields 981.8 N; as the largest available ASQ size, there is no larger bore to step up to within this JIS compact family. The 5mm stroke is well within the 30mm maximum limit for this bore. If your project demands longer travel than 30mm, you must switch to the double-acting ACQ series. When ordering, confirm the 63mm bore, 5mm stroke, female M10x1.5 rod-end thread, and PT1/4 porting.
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 ASQ63X5 FAQ
It provides a theoretical push force of 1558.6 N at 0.5 MPa and 2182 N at 0.7 MPa. These figures represent the air-side force before the return spring is factored in, so the net usable force is lower and must be confirmed from the datasheet. Operating pressure ranges from 0.2 to 1.0 MPa, with a maximum standard stroke of 30mm for this 63mm bore.
This model uses a fixed NBR elastomer bumper at each end to absorb end-of-stroke impact, meaning there is no adjustable air cushion. As a single-acting push type, it relies on an internal spring to retract the rod. If air pressure is lost or falls below the 0.2 MPa minimum needed to overcome the spring, the cylinder automatically returns to its retracted rest position.
