Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10SB 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 ASQ40X10SB
The AirTAC ASQ40X10SB is a single-acting push-type JIS compact cylinder. Feeding compressed air to its PT1/8 port extends the 16mm rod outward, while an internal mechanical spring handles retraction. This design requires only one air line, saving valve plumbing and simplifying your setup. It includes a male M14x1.5 rod-end thread and a built-in piston magnet.
At 0.5 MPa, this 40mm bore unit provides a 628.3N theoretical push force (879.6N at 0.7 MPa). Because an internal return mechanism constantly opposes motion, actual usable output is lower—verify the net value from the datasheet for your specific load. The body relies on a fixed NBR elastomer bumper for end-of-stroke impact absorption rather than an adjustable air cushion. Furthermore, a minimum operating pressure of 0.2 MPa is required to overcome the 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 ASQ40X10SB Is Used
Stamping Ejector
Pushes small stamped metal parts out of a die cavity using a short, reliable 10mm extension.
Transfer Line Diverter
Briefly extends a guide arm to deflect passing packages on a packaging conveyor belt.
Assembly Part Hold-down
Holds a workpiece firmly in place on an automated machining fixture during a fastening cycle.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10SB the Right Cylinder?
For sizing, a 40mm bore offers 628.3N of theoretical extension force at 0.5 MPa. If your payload is lighter, the adjacent 32mm variant yields 402.1N, whereas the larger 50mm option provides 981.8N. The 10mm stroke is well within the 30mm maximum limit for this bore size. Should your application require longer travel than 30mm, you must switch to the double-acting ACQ series. When ordering, verify the 40mm bore, 10mm stroke, S magnet option, and B male-thread rod end.
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 ASQ40X10SB FAQ
It delivers 628.3N theoretical push at 0.5 MPa and 879.6N at 0.7 MPa. Because an internal spring retracts the rod, net output is lower and must be confirmed from the datasheet. Operating pressure is 0.2-1.0 MPa (0.2 MPa minimum to overcome the spring), and the maximum standard stroke for a 40mm bore is 30mm.
It uses a fixed NBR elastomer bumper at the end of the stroke, which is not adjustable. For high kinetic energy loads, an external shock absorber or slower approach speed is recommended. The included -S magnet works with reed or electronic solid-state switches fitted into the body grooves for position detection.
