Airtac ASQ Series Single Acting Slim Cylinder ASQ50X25
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ50X25 is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø50mm bore and 25mm 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 ASQ50X25
The AirTAC ASQ50X25 is a JIS compact single-acting push cylinder. Supplying air to its single PT1/4 port extends the Ø20 mm rod, while an internal spring handles the retraction. It delivers a theoretical push force of 981.8 N at 0.5 MPa (1374.4 N at 0.7 MPa) before accounting for the spring. Because the return mechanism consumes energy, the actual net output is lower, so verify the usable force from the datasheet.
Designed for short-stroke automation, this 50 mm bore actuator provides a 25 mm travel distance. It relies on a fixed NBR elastomer bumper at the stroke ends rather than adjustable pneumatic cushioning. If your machine requires longer movement beyond the 30 mm maximum limit for this bore size, a double-acting ACQ series cylinder is the appropriate alternative.
Airtac ASQ Series Single Acting Slim Cylinder ASQ50X25 Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ50X25 |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 25 mm |
| Acting type | Single acting, push type |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø50mm, Push)
| Pressure | Push force (before spring) |
|---|---|
| 0.5 MPa | 982 N |
| 0.7 MPa | 1374 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 ASQ50X25 Is Used
Sheet Metal Hold-Down
Secures heavy gauge sheet metal against a welding fixture using the 981.8 N theoretical push, releasing instantly when air is cut.
Stamping Ejector
Pushes formed metal components out of a die cavity on an automated press line, utilizing the fixed NBR bumper to absorb impact.
Pallet Flap Folder
Folds corrugated cardboard flaps on high-speed packaging equipment where the internal spring guarantees a safe fail-safe retract.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ50X25 the Right Cylinder?
For sizing context within the 12-63 mm range, the adjacent ASQ40 bore yields a 628.3 N theoretical push at 0.5 MPa, while stepping up to the ASQ63 provides 1558.6 N. If your application needs more than a 30 mm stroke, switch to the double-acting ACQ variant. When ordering this model, verify the 50 mm bore, 25 mm stroke, female M10x1.5 rod-end thread, and note that this configuration ships without the -S magnet option.
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 ASQ50X25 FAQ
It provides a theoretical push of 981.8 N at 0.5 MPa and 1374.4 N at 0.7 MPa before the return spring lowers the net output. Operating pressure is 0.2-1.0 MPa (0.2 MPa minimum to overcome the spring), and the maximum standard stroke for this 50 mm bore is 30 mm.
It uses a fixed NBR elastomer bumper at each end to absorb shock, not an adjustable air cushion. If air pressure is lost, the internal spring automatically retracts the rod to its rest position, ensuring a predictable fail-safe state.
