Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20SB 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 ASQ63X20SB
The AirTAC ASQ63X20SB is a 63mm JIS compact single-acting push cylinder. Feeding air to its single PT1/4 port extends the Ø20mm rod, while an internal mechanical spring handles the retraction. This one-line actuation saves valve plumbing and simplifies your circuit layout. Theoretical push force is 1558.6N at 0.5MPa and 2182N at 0.7MPa, though the return spring lowers net output, so verify the exact net figure from the datasheet.
This specific configuration includes a built-in piston magnet (-S) for tracking with reed or solid-state electronic switches, plus a male M18x1.5 rod-end thread (-B) that mounts directly to tooling. It features a fixed NBR elastomer bumper to soften end-of-stroke contact rather than an adjustable air cushion. If air pressure drops, the fail-safe spring immediately pulls the rod back to its retracted rest position.
Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20SB Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20SB |
|---|---|
| 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 ASQ63X20SB Is Used
Heavy-Duty Stamping Clamp
Holds heavy sheet metal blanks firmly against a die fixture during progressive stamping operations, relying on the robust 63mm bore push force.
Automated Press Ejector
Pushes finished forged parts out of a hydraulic press bed, utilizing the fail-safe spring return to clear the bed during material loading.
Assembly Line Diverter
Acts as a heavy-duty routing gate on a high-mass pallet conveyor, extending to redirect bulky automotive components down a specific lane.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20SB the Right Cylinder?
For sizing within the ASQ family, stepping down to a 50mm bore yields a 981.8N theoretical push at 0.5MPa, while this 63mm bore provides 1558.6N at the same pressure. Note that single-acting strokes are capped at 30mm for this bore; if your application requires longer travel, switch to the double-acting ACQ series. When ordering, confirm the 63mm bore, 20mm stroke, -S magnet for sensors, and -B male M18x1.5 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 ASQ63X20SB FAQ
The theoretical push force is 1558.6N at 0.5MPa and 2182N at 0.7MPa. Because an internal spring retracts the rod, the net usable force is lower; consult the datasheet for exact output. Operating pressure is 0.2-1.0 MPa, with 0.2 MPa minimum required to overcome the spring, and the maximum standard stroke is 30mm.
It is a single-acting push type, so exhausting the air port causes the internal spring to immediately retract the rod to its resting position. End-of-travel deceleration is handled by a fixed NBR elastomer bumper, not an adjustable air cushion. The -S magnet option enables position sensing with either reed or solid-state electronic switches.
