Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20 is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø63mm bore and 20mm 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 ASQ63X20
The AirTAC ASQ63X20 is a 63 mm JIS compact cylinder configured for single-acting push operation. Supplying air to its single PT1/4 port extends the Ø20 mm rod, while an internal mechanical spring handles retraction. This design requires a minimum operating pressure of 0.2 MPa to overcome the return mechanism. Theoretical push output is 1558.6 N at 0.5 MPa and 2182 N at 0.7 MPa, though the internal spring lowers the net usable force, so verify the exact net figure from the official datasheet.
Built without a tie-rod structure, this riveted body unit relies on a fixed NBR elastomer bumper at the stroke ends rather than an adjustable air cushion. It features a 20 mm stroke, well within the 30 mm maximum travel limit for this bore size. The piston rod end utilizes a default female M10x1.5 thread. Although the body includes machined grooves for magnetic switches, this specific configuration ships without the internal magnet.

| 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 ASQ63X20 Is Used
Injection Mold Ejection
Pushes finished plastic parts out of mold cavities using high theoretical force, relying on the internal spring to retract the rod safely during machine cycling.
Heavy Part Hold-Down
Secures dense metal workpieces against a machining fixture during milling, using the single air line to extend and clamp the component firmly.
Pallet Flap Folding
Extends briefly to tuck cardboard flaps on heavy packaging lines, with the spring ensuring the mechanism pulls back clear of the conveyor flow.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X20 the Right Cylinder?
When sizing this 63 mm bore unit, dropping down to the 50 mm bore lowers the theoretical push to 981.8 N at 0.5 MPa. Moving up is not possible as 63 mm is the largest ASQ option. If your automated equipment requires travel beyond 30 mm, you must switch to the double-acting ACQ series instead of trying to extend a single-acting spring model. To finalize your order, confirm the 63 mm bore, 20 mm stroke, the lack of a magnet, and the default female M10x1.5 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 ASQ63X20 FAQ
The theoretical push force (before spring) is 1558.6 N at 0.5 MPa and 2182 N at 0.7 MPa. Because an internal spring returns the rod, the net output force is lower and must be confirmed from the datasheet. Operating pressure ranges from 0.2 MPa to 1.0 MPa, with the 0.2 MPa minimum necessary to overcome the return spring. The maximum standard stroke for this 63 mm bore is 30 mm.
If air pressure is lost, the internal spring automatically retracts the rod to its resting position, providing a fail-safe return. At the end of each stroke, the cylinder relies on a fixed NBR elastomer bumper to absorb impact energy. It does not feature an adjustable air cushion, so for high-speed approaches, you should add an external shock absorber.
