Airtac ASQ Series Single Acting Slim Cylinder ASQ63X15B
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X15B is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø63mm bore and 15mm 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 ASQ63X15B
The AirTAC ASQ63X15B is a single-acting push-type JIS compact cylinder that uses compressed air to extend its 15mm stroke, while an internal mechanical spring handles the retraction. Supplying air to one port simplifies plumbing and valve requirements. As the largest bore in this series, the 63mm piston delivers a theoretical push force of 1558.6N at 0.5MPa and 2182N at 0.7MPa before the spring resistance is factored in; confirm the exact net output from the official datasheet for your specific load.
This specific configuration includes a male M18x1.5 threaded rod end for direct mechanical coupling. It relies on a fixed NBR elastomer bumper at the stroke ends rather than an adjustable air cushion, so external shock absorbers may be needed for high kinetic energy loads. Although the body features magnetic-switch grooves, this particular unit ships without a piston magnet, meaning position sensing is not supported out of the box.

| Bore size | Ø63 mm |
| Stroke | 15 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 ASQ63X15B Is Used
Heavy-Duty Part Clamping
Secures heavy metal castings during CNC machining operations, utilizing the robust 63mm bore push force to hold components rigidly against a fixed stop.
Stamping Ejection
Pushes finished stamped parts out of a press die in automated fabrication lines, relying on the spring-return mechanism to safely withdraw the rod when air pressure is removed.
Pallet Hold-Down
Applies downward pressure to stabilize heavy pallets or fixtures during robotic welding or assembly, ensuring the load does not shift during processing.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X15B the Right Cylinder?
When sizing this 63mm bore actuator, stepping down to the 50mm version drops the theoretical push to 981.8N at 0.5MPa, while the 63mm bore remains the maximum capacity available in this compact frame. If your application requires a stroke longer than the 30mm maximum limit for this single-acting series, you must transition to the double-acting ACQ equivalent. To order, verify your required 15mm travel, confirm the 63mm bore provides adequate net force after spring deduction, and specify the male M18x1.5 rod thread and PT1/4 port connection.
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 ASQ63X15B FAQ
The theoretical push force is 1558.6N at 0.5MPa and 2182N at 0.7MPa. These figures represent the air-side force before deducting the return spring resistance, so the actual net output is lower and should be verified via the datasheet. Operating pressure must be at least 0.2MPa to overcome the spring, and the maximum standard stroke for this 63mm bore is 30mm.
Because it is single-acting push type, exhausting the air port allows the internal spring to automatically retract the rod to its rest position, providing a predictable fail-safe behavior if air pressure is lost. End-of-stroke deceleration is handled by fixed NBR elastomer bumpers, not adjustable air cushions, so high-speed applications may require external shock absorption.
