Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25SB 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 ASQ63X25SB
The AirTAC ASQ63X25SB is a 63mm bore JIS compact cylinder engineered for single-acting push motion. Feeding air into the single PT1/4 port extends the rod, while an internal mechanical spring handles the retraction stroke automatically. This design requires only one solenoid valve and a single air line, greatly simplifying your pneumatic plumbing compared to double-acting units.
At 0.5 MPa, this model generates 1558.6 N of theoretical push force (2182 N at 0.7 MPa) before the return spring's resistance is factored in. You must verify the lower net output from the official datasheet for your specific load. This variant includes a male M18x1.5 piston rod end for direct load coupling, a 25mm stroke within the 30mm maximum limit for this bore, and an NBR elastomer bumper that stops impact at the travel extremes.

| 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 ASQ63X25SB Is Used
Injection Mold Ejection
Uses the male M18x1.5 rod to push finished plastic parts out of the mold cavity, relying on the spring to safely retract the pin during machine cycling.
Heavy-Duty Part Clamping
Holds heavy steel workpieces securely against a stop fixture during machining, with the single-acting design ensuring the clamp releases automatically if air pressure drops.
Pallet Flap Folding
Extends to fold cardboard flaps on large packaging lines, where the fixed NBR bumper absorbs the kinetic energy at the end of the 25mm stroke.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X25SB the Right Cylinder?
For slightly lower force requirements, the adjacent ASQ50 bore offers 981.8 N theoretical push at 0.5 MPa. If your application demands more travel than the 30mm maximum stroke allowed here, the double-acting ACQ series is the correct alternative. When finalizing this ASQ63X25SB unit, verify the 63mm bore, 25mm stroke, the -S magnet for sensing, and the -B male M18x1.5 rod thread.
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 ASQ63X25SB FAQ
It provides 1558.6 N theoretical push at 0.5 MPa and 2182 N at 0.7 MPa. These figures represent the air-side force before the return spring; the net usable force is lower and 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 standard stroke is 30 mm.
If air is lost or exhausted, the internal spring automatically retracts the rod to its rest position. The -S option includes a piston magnet compatible with both reed and electronic solid-state switches via the body grooves. Impact at travel ends is managed by a fixed NBR elastomer bumper, not an adjustable air cushion.
