Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5B
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5B 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 ASQ63X5B
The ASQ63X5B is a JIS compact, single-acting push cylinder where air extends the rod and an internal spring retracts it on exhaust. This 63mm bore model delivers a theoretical push force of 1558.6N at 0.5MPa and 2182N at 0.7MPa before spring deduction. You must confirm the net output from the datasheet, as the return spring lowers the usable force. Operating pressure begins at 0.2MPa to overcome the spring.
Featuring a short 5mm stroke, this unit uses a fixed NBR elastomer bumper for end-of-travel damping rather than an adjustable air cushion. It includes a male M18x1.5 piston rod thread for direct load coupling. While the body retains magnetic-switch grooves, this specific configuration ships without a magnet. If air pressure drops, the spring provides a fail-safe return to the retracted rest position.

| 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 ASQ63X5B Is Used
Heavy-Duty Clamping
Secures thick metal plates in a machining center using the 1558.6N theoretical push, with the spring ensuring the clamp releases when air is removed.
Short-Stroke Ejecting
Pushes finished castings out of a CNC fixture with a quick 5mm motion, relying on the fixed NBR bumper to absorb the impact at high speeds.
Press Pin Locating
Holds alignment pins in an automotive assembly jig, driving them down briefly before the internal spring retracts the male M18x1.5 rod for the next cycle.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X5B the Right Cylinder?
Selecting this 63mm bore actuator involves balancing the 1558.6N theoretical push at 0.5MPa against your load, keeping in mind the spring reduces net output. For lighter duty, the 50mm bore offers 981.8N at 0.5MPa. Since 63mm is the largest ASQ option, higher force demands require a different series. The 5mm stroke is well within the 30mm maximum for this bore; if you need longer travel, switch to the double-acting ACQ. When ordering, verify the 63mm bore, 5mm stroke, PT1/4 port, and the 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 ASQ63X5B FAQ
The theoretical push force is 1558.6N at 0.5MPa and 2182N at 0.7MPa before spring deduction; the return spring lowers the net output, so confirm the exact figure from the datasheet. It requires a minimum operating pressure of 0.2MPa to overcome the spring. This single-acting model has a 5mm stroke, well under the 30mm maximum for a 63mm bore.
Loss of air pressure triggers the internal spring to fail-safe retract the rod to its rest position. End-of-stroke damping is handled by a fixed NBR elastomer bumper, not an adjustable air cushion. For high kinetic energy loads, you should add an external shock absorber or slow the approach speed.
