Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30B
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30B is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø50mm bore and 30mm 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 ASQ50X30B
The ASQ50X30B is a single-acting, push-type JIS compact cylinder where air pressure extends the rod and an internal mechanical spring handles the retraction. Supplying one port simplifies plumbing, requiring just a single solenoid valve to drive the motion. This 50mm bore variant generates a theoretical push force of 981.8N at 0.5MPa and 1374.4N at 0.7MPa. Because the return spring consumes some energy, the actual net output is lower—verify the exact usable force in the official datasheet.
Designed for short-stroke tasks, this unit features a fixed NBR elastomer bumper to absorb end-of-travel impact rather than an adjustable air cushion. It includes a male M18x1.5 rod-end thread for direct load coupling and a 20mm piston rod. The body retains magnetic-switch grooves for position sensing, though this specific SKU ships without the internal magnet. If pressure drops, the spring provides a fail-safe retraction to the resting position.
Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30B Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30B |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 30 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 (Ø50mm, Push)
| Pressure | Push force (before spring) |
|---|---|
| 0.5 MPa | 982 N |
| 0.7 MPa | 1374 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 ASQ50X30B Is Used
Press Die Ejection
Uses the male thread to push stamped parts out of a die after the press opens, relying on the spring to retract the rod before the next cycle.
Heavy Carton Diverting
Extends to deflect heavy corrugated boxes on a packaging line, with the fail-safe spring ensuring the diverter clears the conveyor path on air loss.
Automated Clamping Fixture
Applies up to 1374.4N of theoretical push at 0.7MPa to hold workpieces in a CNC machining station, retracting instantly when exhaust valves open.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30B the Right Cylinder?
When sizing this 50mm bore, dropping to a 40mm version reduces the theoretical push to 628.3N at 0.5MPa, while stepping up to a 63mm bore raises it to 1558.6N. This 30mm stroke represents the maximum standard travel for this bore size; applications needing longer extension must switch to a double-acting ACQ cylinder. To order, confirm the 50mm bore, 30mm stroke, the male M18x1.5 rod thread, and whether your application requires adding the -S magnet option for sensor tracking.
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 ASQ50X30B FAQ
It delivers a theoretical push of 981.8N at 0.5MPa and 1374.4N at 0.7MPa before the return spring lowers the net output. The maximum standard stroke for this 50mm bore is 30mm, and it requires a minimum operating pressure of 0.2MPa to overcome the spring.
It uses a fixed NBR elastomer bumper at the ends to absorb impact, not an adjustable air cushion. If air pressure is lost or exhausted, the internal spring automatically retracts the rod to its starting position, providing a safe default state.
