Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15H
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15H is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø40mm bore and 15mm 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 ASQ40X15H
The AirTAC ASQ40X15H is a JIS compact single-acting push cylinder. Supplying air to its single PT1/8 port extends the Ø16 mm rod, while an internal return spring handles retraction. This design cuts plumbing down to one air line, making it highly efficient for short-stroke automation. Because it is a spring-return unit, operating pressure must be at least 0.2 MPa to overcome the internal mechanism.
At 0.5 MPa, this 40 mm bore generates a theoretical push force of 628.3 N, increasing to 879.6 N at 0.7 MPa. Remember that these figures represent theoretical output before the spring; the return mechanism lowers the net usable force, so confirm the exact net capacity from the official datasheet. The body incorporates fixed NBR elastomer bumpers rather than adjustable air cushions, and while magnetic-switch grooves are machined into the profile, this specific configuration ships without a sensor magnet.
Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15H Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15H |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 15 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 ASQ40X15H Is Used
Stamping Pin Locating
Extends a short 15 mm rod to push a locating pin into position for stamping presses, relying on the spring to safely retract the pin when air is removed.
Packaging Feed Stop
Acts as a compact barrier on a packaging conveyor, extending to halt carton flow and retracting instantly via the internal spring upon exhaust.
Clamping Jig Hold
Provides reliable downward clamping pressure on machining jigs, using its 628.3 N theoretical push to secure parts before the spring releases the grip.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15H the Right Cylinder?
When sizing this 40 mm unit, dropping down to a 32 mm bore reduces the theoretical push to 402.1 N at 0.5 MPa, while stepping up to a 50 mm bore raises it to 981.8 N. This 15 mm stroke falls well within the 30 mm maximum travel limit for this bore size. If your application requires longer extension, you would need to switch to the double-acting ACQ series. To order, confirm the 40 mm bore, 15 mm stroke, default female M8x1.25 rod-end thread, and note that a -S suffix is required if you need a magnet for position sensing.
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 ASQ40X15H 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 reduces the net output. Operating pressure ranges from 0.2 to 1.0 MPa, and the maximum standard stroke for this 40 mm bore is 30 mm.
It uses fixed NBR elastomer bumpers at the ends of travel instead of adjustable air cushions, meaning high-speed operations might need external shock absorbers. If air pressure is lost, the internal spring provides a fail-safe return, pulling the rod back to its retracted resting state.
