Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø40mm 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 ASQ40X15SB
The AirTAC ASQ40X15SB is a JIS compact single-acting push cylinder. Supplying air to its single PT1/8 port extends the Ø16mm rod, while an internal return spring retracts it upon exhaust. This configuration simplifies plumbing by requiring only one air line. The 15mm stroke is well within the 30mm maximum travel limit for this 40mm bore series.
It delivers a theoretical push force of 628.3N at 0.5MPa and 879.6N at 0.7MPa before spring resistance. The return spring lowers the net usable output, so confirm the exact net force from the datasheet. This unit includes a built-in piston magnet for position sensing and a male M14x1.5 rod end. End-of-stroke deceleration is handled by fixed NBR elastomer bumpers, not adjustable air cushions.
Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15SB Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15SB |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 15 mm |
| Acting type | Single acting, push type |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm, Push)
| Pressure | Push force (before spring) |
|---|---|
| 0.5 MPa | 628 N |
| 0.7 MPa | 880 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 ASQ40X15SB Is Used
Injection Mold Ejection
Pushes finished plastic parts out of mold cavities during a short stroke, with the internal spring guaranteeing a safe, automatic retract if air pressure is lost.
CNC Clamping Arm
Extends a short 15mm stroke to secure metal workpieces against a fixture, utilizing the male M14x1.5 thread for direct tool mounting.
Carton Flap Hold-down
Holds cardboard flaps momentarily during a packaging sequence, where the fixed NBR bumper absorbs the impact at the end of the extension cycle.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X15SB the Right Cylinder?
For sizing within the 12-63mm bore range, stepping down to a 32mm bore drops the 0.5MPa theoretical push to 402.1N, while stepping up to a 50mm bore increases it to 981.8N. If your application requires a longer travel distance beyond the 30mm maximum for this single-acting series, the double-acting ACQ compact cylinder is the correct alternative. When ordering this ASQ40X15SB, the essentials are covered: 40mm bore, 15mm stroke, S magnet for electronic or reed switches, and B male rod threading.
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 ASQ40X15SB FAQ
This single-acting push cylinder provides a theoretical force of 628.3N at 0.5MPa and 879.6N at 0.7MPa before the return spring is factored in. It requires a minimum operating pressure of 0.2MPa to overcome the spring and has a 15mm stroke, which is under the 30mm maximum limit for this 40mm bore.
If air pressure is lost or exhausted, the internal spring automatically retracts the rod to its resting position, preventing damage to downstream tooling. The included -S magnet allows you to track piston position using either reed or solid-state electronic switches mounted in the body grooves.
