Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10S
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10S 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 ASQ40X10S
The AirTAC ASQ40X10S is a JIS compact, single-acting push cylinder. Supplying air to its single PT1/8 port extends the 16mm rod, while an internal spring handles retraction. This design cuts plumbing to one line and guarantees fail-safe retraction to the rest position if air pressure drops.
At 40mm bore, it delivers 628.3N of theoretical push at 0.5 MPa (879.6N at 0.7 MPa) before spring deduction; verify the net output via the datasheet. The 10mm stroke is well within the 30mm maximum for this bore, and the -S magnet enables tracking with reed or solid-state switches.
Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10S Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10S |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø40 mm |
| 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.

Thread: PT standard (G / NPT available). ASQ pushes out / spring returns; ATQ pulls in / spring extends. Related: ACQ (double acting), ACQD (double rod), ACQJ (adjustable stroke).
Where the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10S Is Used
Stamping Pin Ejection
Uses the 10mm stroke to push finished parts out of a die set, relying on the internal spring to retract the pin safely during the press cycle.
Package Diverter
Extends briefly to deflect cartons on a packaging line, with the fail-safe spring ensuring the diverter clears the conveyor path when air is removed.
Fixture Clamping
Holds aluminum extrusions in place for a machining center, using the 628.3N theoretical push at 0.5 MPa to maintain position during light milling.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10S the Right Cylinder?
For sizing, dropping to a 32mm bore lowers the 0.5 MPa theoretical push to 402.1N, whereas stepping up to a 50mm bore raises it to 981.8N. If your mechanism requires a stroke beyond 30mm, switch to the double-acting ACQ series. When ordering this 40mm bore unit, confirm the 10mm stroke, the -S magnet option, and the default female M8x1.25 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 ASQ40X10S FAQ
It provides a theoretical push of 628.3N at 0.5 MPa and 879.6N at 0.7 MPa. Because an internal spring retracts the rod, the net output force is lower; consult the datasheet for exact net figures. Operating pressure is 0.2-1.0 MPa, with a 0.2 MPa minimum needed to overcome the spring, and the 10mm stroke is within the 30mm maximum for this bore.
It uses a fixed NBR elastomer bumper at the ends to absorb impact, rather than an adjustable air cushion. For high-speed loads, consider external shock absorption. The -S option includes a piston magnet compatible with reed or solid-state switches for position tracking.
