Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø63mm bore and 5mm 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 ASQ63X5SB
The AirTAC ASQ63X5SB is a single-acting push-type JIS compact cylinder. Supplying air to the single PT1/4 port extends the Ø20 mm rod, while an internal mechanical spring retracts it upon exhaust. This design simplifies plumbing by needing just one air line. At 0.5 MPa, it delivers a theoretical push of 1558.6 N (2182 N at 0.7 MPa) before spring deduction; verify the net output via the datasheet.
Equipped with -S and -B options, this unit features a male M18x1.5 rod-end thread for direct load coupling and an integrated piston magnet for position sensing. It utilizes a fixed NBR elastomer bumper to soften end-of-stroke impacts rather than an adjustable air cushion. Furthermore, the spring provides a fail-safe return, driving the rod back to its retracted rest position if air pressure drops below the 0.2 MPa minimum or is lost entirely.
Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5SB Technical Specifications

|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø63 mm |
| Stroke | 5 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 ASQ63X5SB Is Used
Heavy-Duty Part Clamping
Secures thick metal plates against a CNC machining fixture using the robust 63 mm bore extension force.
Stamping Ejection
Pushes finished stamped components out of a heavy press die, relying on the spring to safely retract the pin.
Pallet Hold-Down
Applies downward pressure to lock large wooden pallets stationary during automated banding operations.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5SB the Right Cylinder?
For sizing, stepping down to a 50 mm bore reduces the theoretical push at 0.5 MPa to 981.8 N, whereas moving up is impossible as 63 mm is the largest ASQ option. If your application requires a stroke longer than the 30 mm maximum limit for this series, a double-acting ACQ cylinder is necessary. To order this 5 mm stroke unit, confirm the 63 mm bore, the male M18x1.5 rod thread (-B), and the magnet (-S) for electronic or reed switch compatibility.
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 ASQ63X5SB FAQ
It provides a theoretical push of 1558.6 N at 0.5 MPa and 2182 N at 0.7 MPa before the return spring lowers the net output. Operating pressure is 0.2-1.0 MPa, requiring a 0.2 MPa minimum to overcome the spring. The stroke is 5 mm, well within the 30 mm maximum for this bore.
If air is lost, the internal spring automatically returns the rod to its retracted rest position. At each end of the body, a fixed NBR elastomer bumper absorbs impact energy; it is not an adjustable air cushion, so external shock absorbers may be needed for very high speeds.
