Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20H
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20H is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø63mm bore and 20mm 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 ASQ63X20H
The AirTAC ASQ63X20H is a JIS compact single-acting push cylinder. Supplying air to its single PT1/4 port extends the 20mm rod, while an internal mechanical spring retracts it upon exhaust. This design requires only one pneumatic line, simplifying plumbing and valve requirements. Operating pressure begins at 0.2 MPa, which is the minimum threshold needed to overcome the return spring.
At 0.5 MPa, this 63mm bore unit generates 1558.6 N of theoretical push force, increasing to 2182 N at 0.7 MPa. These figures represent the air-side pressure before the spring resistance is factored in; the actual net output is lower and should be verified from the official datasheet. The body features a fixed NBR elastomer bumper for end-of-stroke impact absorption and includes integrated magnetic-switch grooves, though this specific configuration ships without the internal magnet.
Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20H Technical Specifications

| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø63 mm |
| Stroke | 20 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 ASQ63X20H Is Used
Stamping Press Ejection
Uses the 1558.6N theoretical push at 0.5MPa to eject heavy stamped metal blanks from a die cavity, relying on the internal spring to retract the rod safely when air is removed.
Automated Clamping Fixture
Holds large automotive castings securely in place during CNC machining, utilizing the fail-safe spring-return feature to release the part automatically if compressed air pressure drops.
Assembly Line Plunging
Drives heavy riveting or pin-locating heads on an automated assembly conveyor, with the fixed NBR bumper absorbing the impact energy at the end of the 20mm extension stroke.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20H the Right Cylinder?
For sizing context within the 12-63mm ASQ range, the 50mm bore variant offers a lower theoretical push of 981.8 N at 0.5 MPa, while this 63mm version provides the maximum 1558.6 N at 0.5 MPa. If your application requires a stroke longer than the 30mm maximum limit for single-acting models, the double-acting ACQ series is the correct alternative. To finalize this exact build, confirm the 63mm bore, 20mm stroke, female M10x1.5 rod thread, and PT1/4 port.
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 ASQ63X20H FAQ
It provides a theoretical push force of 1558.6N at 0.5MPa and 2182N at 0.7MPa. These are air-side calculations before the return spring is factored in; net output is lower and must be confirmed via the datasheet. Because it is single-acting, a minimum operating pressure of 0.2MPa is required to overcome the spring, and the maximum standard stroke is 30mm.
It uses a fixed NBR elastomer bumper at the stroke ends to absorb impact, which is not adjustable like a pneumatic cushion. The body includes grooves for mounting reed or solid-state electronic switches, but this specific model ships without the internal magnet, so position sensing is not supported unless a version with the -S option is specified.
