Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25B
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25B is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø63mm 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 ASQ63X25B
The AirTAC ASQ63X25B is a 63mm bore JIS compact cylinder engineered for single-acting push operation. Feeding air to the single PT1/4 port extends the rod, while an internal mechanical spring handles the retraction upon exhaust. This configuration simplifies plumbing by requiring just one air line. At 0.5 MPa, the unit delivers a 1558.6 N theoretical push force (2182 N at 0.7 MPa) before the return spring's resistance. Because the spring lowers the actual net output, you should verify the precise net force from the official datasheet for your specific load.
Designed with a 25mm stroke within the 30mm maximum limit for this bore, it features a fixed NBR elastomer bumper to manage end-of-travel impact rather than an adjustable air cushion. The rod end utilizes a male M18x1.5 thread for direct load coupling. Operating pressure spans 0.2-1.0 MPa, with the 0.2 MPa floor necessary to overcome the return spring. If pneumatic supply is lost, the spring ensures a fail-safe retraction back to the resting position.

| 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 (Ø63mm, Push)
| Pressure | Push force (before spring) |
|---|---|
| 0.5 MPa | 1559 N |
| 0.7 MPa | 2182 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 ASQ63X25B Is Used
Injection Mold Ejection
Pushes finished plastic parts out of an injection molding die using the 1558.6 N theoretical force, relying on the internal spring to retract the rod when air is cut.
Heavy Carton Flap Hold-down
Extends to hold heavy corrugated carton flaps during automated taping, with the fail-safe spring ensuring the rod pulls back if the air supply drops.
Stamping Blank Ejection
Ejects heavy metal stamping blanks from a press bed using the male M18x1.5 thread for a robust tool connection, absorbing impact via the fixed NBR bumper.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25B the Right Cylinder?
For sizing, the 63mm bore offers the highest push capacity in the ASQ family. If 1558.6 N theoretical force at 0.5 MPa is excessive, step down to the 50mm bore (981.8 N). Since 63mm is the largest available, exceeding its force requires moving to a different cylinder series. This 25mm stroke is valid (max 30mm); for longer travel, switch to the double-acting ACQ. To order: confirm 63mm bore, 25mm stroke, the -B male M18x1.5 rod thread, and note this unit lacks 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 ASQ63X25B FAQ
The theoretical push force is 1558.6 N at 0.5 MPa and 2182 N at 0.7 MPa. This is before the return spring lowers the net output, which must be confirmed from the datasheet. Operating pressure is 0.2-1.0 MPa, with 0.2 MPa minimum required to overcome the spring, and the maximum stroke for this 63mm bore is 30 mm.
As a single-acting push type, losing air pressure causes the internal spring to automatically retract the rod to its resting position. End-of-stroke impact is controlled by a fixed NBR elastomer bumper, not an adjustable air cushion, so for high kinetic energy loads you should slow the approach or use an external shock absorber.
