Airtac ASQ Series Single Acting Slim Cylinder ASQ63X15
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X15 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 ASQ63X15
The AirTAC ASQ63X15 is a single-acting push-type JIS compact cylinder. Supplying air to its single PT1/4 port extends the 20mm rod, while an internal spring handles retraction. This simplifies plumbing to just one solenoid line. Theoretical push force is 1558.6N at 0.5 MPa and 2182N at 0.7 MPa before the return spring's resistance lowers net output; verify the exact net figure from the datasheet.
Designed with a 63mm bore and a 15mm stroke, this unit uses a fixed NBR elastomer bumper for end-of-travel dampening rather than an adjustable air cushion. The body includes magnetic-switch grooves, though this specific configuration ships without the -S magnet. Operating pressure spans 0.2-1.0 MPa, requiring a minimum 0.2 MPa to overcome the spring. If air pressure drops, the spring provides a fail-safe retraction to the rest position.
Airtac ASQ Series Single Acting Slim Cylinder ASQ63X15 Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ63X15 |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| 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 ASQ63X15 Is Used
Injection Mold Ejection
Pushes finished plastic parts out of a mold cavity using high force over a short 15mm travel distance.
Heavy-Duty Part Clamping
Holds large metal workpieces securely against a CNC machining fixture during aggressive milling operations.
Press Die Hold-Down
Applies downward pressure to keep a stamping die aligned and stationary before the press cycle begins.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X15 the Right Cylinder?
For sizing, the neighboring 50mm bore yields a 981.8N theoretical push at 0.5 MPa, while this 63mm unit provides 1558.6N. If your application requires a stroke beyond the 30mm maximum limit for this single-acting series, a double-acting ACQ cylinder is required. When ordering, confirm the 63mm bore, 15mm stroke, the default female M10x1.5 rod thread, and whether you need the -S magnet and -B male M18x1.5 thread options.
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 ASQ63X15 FAQ
It delivers a theoretical push of 1558.6N at 0.5 MPa and 2182N at 0.7 MPa before the spring reduces net output. The stroke is 15mm, with a 30mm maximum for this 63mm bore. It requires a 0.2-1.0 MPa operating pressure, needing at least 0.2 MPa to overcome the spring.
It uses a fixed NBR elastomer bumper for end-stop dampening, not an adjustable air cushion. Because it is single-acting, a loss of air pressure causes the internal spring to retract the rod automatically, providing a fail-safe return to the rest position.
