Airtac ASQ Series Single Acting Slim Cylinder ASQ50X15B
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ50X15B 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 ASQ50X15B
The AirTAC ASQ50X15B is a JIS compact single-acting push-type cylinder. Supplying air to its single PT1/4 port extends the rod, while an internal mechanical spring handles the retraction. This model delivers a theoretical push force of 981.8 N at 0.5 MPa and 1374.4 N at 0.7 MPa. Keep in mind these figures represent the air-side pressure before the return spring is factored in; verify the net output from the official datasheet for your specific load.
Designed with a 50 mm bore and a 15 mm stroke, this unit features a male M18x1.5 piston rod end for direct load coupling. It uses a fixed NBR elastomer bumper at the stroke ends rather than an adjustable air cushion. Because it is single-acting, it requires a minimum 0.2 MPa operating pressure to overcome the internal spring, ensuring a fail-safe retraction to the rest position whenever air pressure is lost.

|---|---|
| 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 ASQ50X15B Is Used
Stamping Press Ejection
Uses the 15 mm stroke to push finished metal blanks out of a stamping die, relying on the spring to safely withdraw the rod before the next press cycle.
CNC Fixture Clamping
Applies the 981.8 N theoretical push at 0.5 MPa to secure heavy aluminum castings inside a CNC machining center, releasing instantly upon air exhaust.
Carton Flap Folding
Extends briefly to fold corrugated cardboard flaps on a packaging line, where the compact body and fixed NBR bumper handle the repetitive end-of-stroke impact.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ50X15B the Right Cylinder?
For lower force requirements, the adjacent ASQ40X15B provides a theoretical push of 628.3 N at 0.5 MPa. If your application demands greater thrust, the ASQ63X15B offers 1558.6 N at 0.5 MPa. This ASQ50X15B is limited to a 30 mm maximum travel; if your machine cycle requires a longer distance, select the double-acting ACQ series instead. When ordering, confirm the 50 mm bore, 15 mm stroke, the male M18x1.5 rod thread, and note that this configuration ships without a magnet.
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 ASQ50X15B FAQ
The theoretical push force is 981.8 N at 0.5 MPa and 1374.4 N at 0.7 MPa. This is the air-side force before the return spring reduces the net output, which should be confirmed via the datasheet. Operating pressure must be 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the spring. The maximum standard stroke for this bore is 30 mm.
As a single-acting push cylinder, it automatically retracts to its rest position via the internal spring if air pressure is lost or exhausted. Instead of an adjustable air cushion, it relies on a fixed NBR elastomer bumper at each end to absorb end-of-stroke energy. Note that this specific model lacks a piston magnet, though the body retains sensor grooves.
