Airtac ASQ Series Single Acting Slim Cylinder ASQ50X15
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ50X15 is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø50mm bore and 15mm 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 ASQ50X15
The AirTAC ASQ50X15 is a single-acting push-type JIS compact cylinder. Supplying air to its single PT1/4 port extends the rod, while an internal mechanical spring retracts it upon exhaust. This design requires a minimum operating pressure of 0.2 MPa to overcome the return mechanism. At 50mm bore, it delivers a theoretical push force of 981.8 N at 0.5 MPa and 1374.4 N at 0.7 MPa before spring deduction. You should verify the net output force from the official datasheet.
This 15mm stroke unit features a 20mm piston rod with a female M10x1.5 end thread. End-of-travel deceleration relies on a fixed NBR elastomer bumper rather than an adjustable air cushion. Although the body contains magnetic-switch grooves for position sensing, this specific configuration ships without the internal magnet. If air pressure drops, the spring provides a fail-safe retraction back to the start position.
Airtac ASQ Series Single Acting Slim Cylinder ASQ50X15 Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ50X15 |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 15 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 ASQ50X15 Is Used
Press Die Ejection
Uses the 981.8N theoretical push to eject stamped metal blanks from a press die, relying on the spring return to clear the tooling for the next cycle.
Carton Flap Hold-down
Extends 15mm to hold corrugated carton flaps in place during automated tape sealing, retracting safely if the compressed air supply fails.
Component Seating
Pushes machined components firmly into machining fixtures against a hard stop, with the fixed NBR bumper absorbing the end-stroke impact.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ50X15 the Right Cylinder?
For sizing context, stepping down to a 40mm bore reduces the 0.5 MPa theoretical push to 628.3 N, while a 63mm bore raises it to 1558.6 N. If your application requires a longer extension than the 30mm maximum stroke limit for this 50mm series, you must switch to the double-acting ACQ equivalent. When ordering this single-acting model, confirm the 15mm stroke, the default female rod thread, and whether you need the -S magnet option 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 ASQ50X15 FAQ
The theoretical push force is 981.8 N at 0.5 MPa and 1374.4 N at 0.7 MPa. Because an internal spring returns the rod, the net usable force is lower and must be confirmed from the datasheet. It requires a minimum operating pressure of 0.2 MPa and has a maximum standard stroke of 30mm.
Deceleration is handled by a fixed NBR elastomer bumper at the ends, not an adjustable air cushion. The body includes grooves for reed or solid-state switches, but this specific model ships without the internal magnet, so external sensors will not detect the piston.
