Airtac ASQ Series Single Acting Slim Cylinder ASQ40X5SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ40X5SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø40mm bore and 5mm 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 ASQ40X5SB
The AirTAC ASQ40X5SB is a single-acting push-type JIS compact cylinder. Supplying air to the single PT1/8 port extends the Ø16 mm rod, while an internal spring handles the retraction. This design requires only one air line, simplifying valve plumbing. It includes a male M14x1.5 rod-end thread for direct load coupling and a built-in magnet for position sensing.
Operating pressure ranges from 0.2 to 1.0 MPa, with a 0.2 MPa minimum required to overcome the return spring. The theoretical push force is 628.3 N at 0.5 MPa and 879.6 N at 0.7 MPa before spring deduction; the actual net output is lower, so verify the exact figure from the datasheet. Instead of adjustable air cushions, it relies on a fixed NBR elastomer bumper at the stroke ends to absorb impact.
Airtac ASQ Series Single Acting Slim Cylinder ASQ40X5SB Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ40X5SB |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 5 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.

Thread: PT standard (G / NPT available). ASQ pushes out / spring returns; ATQ pulls in / spring extends. Related: ACQ (double acting), ACQD (double rod), ACQJ (adjustable stroke).
Where the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X5SB Is Used
Short-Stroke Part Clamping
Ideal for holding metal castings securely in place on a CNC machining center using its 5 mm extension.
Package Ejection
Pushes completed cardboard cartons off a packaging line conveyor belt reliably with every cycle.
Component Pressing
Applies downward pressure to seat small bearings or pins into housings on automated assembly machinery.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ40X5SB the Right Cylinder?
For sizing context, stepping down to a Ø32 bore yields a 402.1 N theoretical push at 0.5 MPa, while stepping up to a Ø50 bore provides 981.8 N. This Ø40 model fits squarely in the mid-range. Its 5 mm stroke is well within the 30 mm maximum limit for this bore. If your application requires longer travel, consider the double-acting ACQ series instead. To finalize your order, confirm the bore (40 mm), stroke (5 mm), -S magnet for switches, and -B male 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 ASQ40X5SB FAQ
The theoretical push force (before spring) is 628.3 N at 0.5 MPa and 879.6 N at 0.7 MPa. The return spring lowers the net usable force, so confirm the exact output from the datasheet. It requires a 0.2 MPa minimum operating pressure to overcome the spring, and the maximum standard stroke for a 40 mm bore is 30 mm.
As a single-acting push cylinder, the internal spring automatically retracts the rod to its rest position if air pressure is lost. At the stroke ends, a fixed NBR elastomer bumper absorbs impact energy; it is not an adjustable air cushion, so for very high cycle speeds you may need an external shock absorber.
