Airtac ASQ Series Single Acting Slim Cylinder ASQ25X10
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ25X10 is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø25mm 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 ASQ25X10
The AirTAC ASQ25X10 is a single-acting push-type JIS compact cylinder that extends its 12mm rod using compressed air, while an internal mechanical spring handles the retraction. Feeding one M5x0.8 port extends the rod; venting that line allows the spring to pull it back. This design requires a minimum 0.2 MPa operating pressure to overcome the internal spring force. With a 25mm bore, it yields a 245.4 N theoretical push at 0.5 MPa and 343.6 N at 0.7 MPa. Note that these are pre-spring figures; the actual net output is lower and should be verified via the datasheet.
Designed for space-constrained setups, this 10mm stroke unit features a fixed elastomer bumper to soften end-of-travel impacts rather than an adjustable air cushion. The body includes standard magnetic-switch grooves, though this specific configuration ships without the internal magnet. Should you need longer travel beyond the 30mm maximum limit for this bore size, the double-acting ACQ series would be required instead.

| Acting type | Single acting, push type |
| Port size | M5×0.8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø25mm, Push)
| Pressure | Push force (before spring) |
|---|---|
| 0.5 MPa | 245 N |
| 0.7 MPa | 344 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 ASQ25X10 Is Used
CNC Fixture Clamping
Holds aluminum blocks firmly against a milling vise jaw using 245.4 N of theoretical push, releasing instantly when air is exhausted.
Package Diverter Arm
Pushes small cardboard cartons off a packaging line using a short 10mm stroke, with the spring ensuring the diverter retracts on air loss.
Part Ejector Station
Briefly extends to knock stamped metal parts out of a die, relying on the fixed elastomer bumper to absorb the impact at the end of travel.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ25X10 the Right Cylinder?
For sizing context, dropping to a 20mm bore reduces the 0.5 MPa theoretical push to 157.1 N, whereas stepping up to a 32mm bore increases it to 402.1 N. This 25mm bore provides a solid middle ground for moderate clamping jobs. The 10mm stroke is well within the 30mm maximum standard stroke limit for this bore. If your application requires longer travel, you must transition to the double-acting ACQ equivalent. When ordering, confirm the 25mm bore, 10mm stroke, female M6x1.0 rod-end thread, PT port thread, and whether you need the -S magnet option 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 ASQ25X10 FAQ
The theoretical push force (before spring) is 245.4 N at 0.5 MPa and 343.6 N at 0.7 MPa. Because it is single-acting, the internal return spring reduces the net output force, which must be confirmed from the datasheet. It requires a minimum operating pressure of 0.2 MPa to overcome the spring, and the maximum standard stroke for this 25mm bore is 30 mm.
As a single-acting push-type cylinder, a loss of air pressure causes the internal spring to automatically retract the rod to its resting position, providing a fail-safe return. Additionally, it uses a fixed elastomer bumper at the end of travel to absorb shock rather than an adjustable cushion, so external shock absorbers may be needed for high-energy loads.
