Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10SG
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10SG is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø40mm bore and 10mm 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 ASQ40X10SG
The AirTAC ASQ40X10SG is a single-acting push-type JIS compact cylinder. Supplying air to its single PT1/8 port extends the 16mm rod outward, while an internal mechanical spring handles retraction. This design simplifies plumbing by requiring only one air line to drive motion. At 0.5 MPa, it generates a 628.3 N theoretical push force (879.6 N at 0.7 MPa) before spring resistance. Because the return spring consumes some energy, the actual net output is lower; verify the exact net force from the official datasheet for your specific load.
This 40mm bore unit features a fixed NBR elastomer bumper at each end to soften end-of-stroke impact, which is not an adjustable air cushion. The -SG option includes a built-in piston magnet for position sensing alongside a male M14x1.5 rod-end thread. If air pressure drops completely, the spring provides a fail-safe action, immediately pulling the rod back to its retracted rest state. Operating pressure must be at least 0.2 MPa to overcome the internal spring.

| Stroke | 10 mm |
| Acting type | Single acting, push type |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm, Push)
| Pressure | Push force (before spring) |
|---|---|
| 0.5 MPa | 628 N |
| 0.7 MPa | 880 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 ASQ40X10SG Is Used
Press Brake Pin Locating
Pushes a spring-loaded alignment pin into position to secure sheet metal blanks on a press brake, retracting automatically when air is removed.
Package Routing Diverter
Extends a 10mm stroke flap to momentarily divert small cardboard cartons off a main packaging conveyor line.
Stamping Press Hold-Down
Applies a compact clamping force to hold a workpiece flat against a fixture during a light-duty automated stamping cycle.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10SG the Right Cylinder?
When sizing this 40mm bore actuator, compare its 628.3 N theoretical push at 0.5 MPa against neighboring bores. Dropping to a 32mm bore lowers the theoretical push to 402.1 N, whereas stepping up to a 50mm bore raises it to 981.8 N. This ASQ40X10SG provides a 10mm travel distance, well under the 30mm maximum limit for this bore size. If your mechanism requires a longer extension than 30mm, you must switch to the double-acting ACQ series instead. To finalize your order, confirm the 40mm bore, 10mm stroke, the -S magnet requirement, and the male M14x1.5 rod 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 ASQ40X10SG FAQ
The theoretical push force is 628.3 N at 0.5 MPa and 879.6 N at 0.7 MPa. These figures represent the air-side force before the return spring; the net output is lower and should be confirmed via the datasheet. Operating pressure ranges from 0.2 MPa (minimum required to overcome the spring) to 1.0 MPa, with a maximum standard stroke of 30mm for this 40mm bore.
As a single-acting push cylinder, an internal spring automatically retracts the rod to its rest position whenever air pressure is lost or exhausted, providing reliable fail-safe behavior. End-of-stroke impact is managed by a fixed NBR elastomer bumper, not an adjustable air cushion. The -S magnet option allows you to track piston position using either reed or electronic solid-state switches.
