Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10B
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10B 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 ASQ40X10B
The AirTAC ASQ40X10B is a JIS compact single-acting push cylinder. Feeding compressed air to its single PT1/8 port extends the 16mm rod outward by 10mm; venting the air allows an internal spring to retract it. This one-air-line setup simplifies plumbing and provides a fail-safe return to the rest position upon loss of air pressure.
Delivering 628.3 N of theoretical push at 0.5 MPa (879.6 N at 0.7 MPa), this 40mm bore unit requires a 0.2 MPa minimum operating pressure to overcome the spring. The listed forces are theoretical values before spring resistance; the return spring lowers the net output, so verify the exact net figure from the datasheet. This configuration includes a male M14x1.5 rod-end thread for direct load coupling. End-of-travel deceleration is handled by fixed NBR elastomer bumpers, not adjustable pneumatic cushions.
Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10B Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10B |
|---|---|
| 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.

Where the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10B Is Used
CNC Fixture Clamping
Secures aluminum castings during machining operations. The spring-return mechanism guarantees the clamp retracts away from the workpiece if shop air drops suddenly.
Package Diverter Pusher
Extends 10mm to deflect flat cartons on a packaging conveyor line. The single-air-line design minimizes valve complexity on multi-gated sorting machines.
Stamping Pin Locator
Positions alignment pins in a press die. The fixed NBR bumper absorbs the hard stop at the end of the stroke, protecting the die alignment from shock impact.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X10B the Right Cylinder?
For sizing, compare this 40mm bore (628.3 N theoretical push at 0.5 MPa) against the adjacent 32mm option (402.1 N) or the larger 50mm bore (981.8 N) to match your load. The 10mm stroke is well within the 30mm maximum limit for this bore; if your application requires longer travel, switch to the double-acting ACQ series. When ordering, confirm the 40mm bore, 10mm stroke, male M14x1.5 rod thread (-B), and note this unit ships without a magnet (-S omitted).
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 ASQ40X10B FAQ
The theoretical push force is 628.3 N at 0.5 MPa and 879.6 N at 0.7 MPa. These figures represent air-side force before the return spring; the internal spring lowers the net usable output, which must be confirmed from the datasheet. Operating pressure is 0.2-1.0 MPa, with the 0.2 MPa minimum required to overcome the spring. Maximum standard stroke for this 40mm bore is 30mm.
It uses fixed NBR elastomer bumpers at the ends of travel to absorb shock, rather than adjustable air cushions. Because it is single-acting push type, the internal spring automatically retracts the rod to its rest position if air pressure is lost or exhausted, providing a fail-safe return. Note that this specific model lacks the -S magnet, so it cannot trigger reed or solid-state sensors.
