Airtac ASQ Series Single Acting Slim Cylinder ASQ50X10SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ50X10SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø50mm bore and 10mm 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 ASQ50X10SB
The AirTAC ASQ50X10SB is a JIS compact single-acting push cylinder. Feeding compressed air to its single PT1/4 port extends the rod, while an internal mechanical spring retracts it upon exhaust. This design simplifies plumbing by needing just one valve line. With a 50 mm bore, it delivers 981.8 N of theoretical push force at 0.5 MPa and 1374.4 N at 0.7 MPa. Because the internal return spring consumes energy, the net output is lower—always verify the exact net figure from the official datasheet.
This unit features a 10 mm stroke, safely within the 30 mm maximum limit for this bore size. It includes a fixed NBR elastomer bumper at the stroke ends for impact absorption rather than an adjustable air cushion. The -S option provides a built-in piston magnet compatible with both reed and solid-state electronic switches, while the -B option supplies a male M18x1.5 rod-end thread for direct load coupling. If air pressure drops, the spring ensures a fail-safe retraction to the rest position.
Airtac ASQ Series Single Acting Slim Cylinder ASQ50X10SB Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ50X10SB |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 10 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 ASQ50X10SB Is Used
CNC Fixture Clamping
Holds aluminum castings firmly against a machining stop using 981.8 N of theoretical push, retracting automatically when the spindle halts.
Packaging Line Diverter
Pushes corrugated cartons onto a secondary sorting lane with a short 10 mm stroke, relying on the spring to withdraw the pin during gaps.
Injection Mold Ejector
Thrusts finished plastic parts out of a mold cavity using the male M18x1.5 thread, returning to a safe rest position upon air loss.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ50X10SB the Right Cylinder?
This 50 mm bore actuator provides 981.8 N of theoretical push at 0.5 MPa. Stepping down to a 40 mm bore drops the theoretical push to 628.3 N, whereas a 63 mm bore raises it to 1558.6 N. The 10 mm stroke specified here is well under the 30 mm single-acting maximum. If your mechanism requires travel beyond 30 mm, you must switch to the double-acting ACQ series instead. When ordering, confirm the 50 mm bore, 10 mm stroke, -S magnet for sensing, and -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 ASQ50X10SB FAQ
It generates 981.8 N theoretical push at 0.5 MPa and 1374.4 N at 0.7 MPa. These are air-side figures before the return spring; the net usable force is lower, so confirm the exact value from the datasheet. Operating pressure is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the spring. The maximum stroke for this 50 mm bore is 30 mm.
It uses a fixed NBR elastomer bumper at the ends to absorb impact, meaning there is no adjustable air cushion. The -S option adds a piston magnet for position sensing, compatible with both reed and electronic solid-state switches. The -B option provides a male M18x1.5 thread for direct mounting.
