Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20S
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20S 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 ASQ63X20S
The AirTAC ASQ63X20S 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 retracts it upon exhaust. This configuration requires only one air line, simplifying plumbing and valve requirements. Theoretical push force is 1558.6N at 0.5MPa and 2182N at 0.7MPa; because the return spring consumes energy during retraction, net output is lower and must be verified against the official datasheet.
Designed for short-stroke automation, this 20mm travel unit includes the -S piston magnet for position sensing. The grooves accept both reed and solid-state electronic switches. Travel stops are managed by a fixed NBR elastomer bumper rather than an adjustable air cushion, making external shock absorbers advisable for high-speed cycling. Should air pressure drop, the spring provides a fail-safe return to the retracted rest position.

| 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 ASQ63X20S Is Used
Heavy Part Ejection
Ejecting dense molded components from a press bed using a short 20mm push stroke powered by 1558.6N of theoretical force at 0.5MPa.
Stamping Hold-Down
Securing heavy steel plates during a stamping operation, utilizing the spring-return mechanism to safely release the part upon air exhaustion.
Pallet Stopper
Acting as a robust pneumatic stop pin on a high-capacity conveyor line, extending to halt pallets and retracting via the internal spring.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20S the Right Cylinder?
Select this 63mm bore model when an application demands high push force within a compact footprint. If 1558.6N theoretical push at 0.5MPa exceeds requirements, consider the 50mm bore variant (981.8N). This bore represents the maximum size in the ASQ series. The 20mm stroke is well within the 30mm limit for this diameter; for longer travel, the double-acting ACQ series is necessary. Confirm ordering details including the 63mm bore, 20mm stroke, -S magnet, and default female M10x1.5 rod end thread.
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 ASQ63X20S FAQ
The theoretical push force is 1558.6N at 0.5MPa and 2182N at 0.7MPa. This is the air-side force before the return spring; net output is lower and should be confirmed from the datasheet. Operating pressure is 0.2-1.0MPa, with a 0.2MPa minimum required to overcome the spring, and the maximum standard stroke is 30mm.
It uses a single-acting push design where exhausting the air allows the internal spring to fail-safe retract the rod to its rest position. End-of-stroke deceleration is handled by a fixed NBR elastomer bumper, not an adjustable air cushion, so external shock absorbers may be needed for high kinetic energy loads.
