Airtac ATQ Single Acting Thin Cylinder ATQ40X10B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ40X10B is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø40mm bore and 10mm stroke. Air pulles 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 ATQ Single Acting Thin Cylinder ATQ40X10B
The ATQ40X10B is a JIS compact single-acting PULL cylinder. Feeding air to its single PT1/8 port retracts the 16 mm rod, while an internal mechanical spring drives the extension stroke. This fail-safe design ensures the rod extends outward to its resting position whenever air pressure drops, fitting tensioning and hold-down-release logic perfectly. Theoretical pull force is 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, though the return spring lowers net output so confirm exact figures from the datasheet.
This 40 mm bore variant provides a 10 mm stroke, well under the 30 mm single-acting maximum. It features a fixed NBR elastomer bumper absorbing end-of-travel energy rather than an adjustable air cushion. The -B suffix indicates a male M14x1.5 piston rod end, coupling directly to your load. Although the body retains magnetic-switch grooves, this specific configuration ships without a magnet.
Airtac ATQ Single Acting Thin Cylinder ATQ40X10B Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ40X10B |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 10 mm |
| Acting type | Single acting, pull 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, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
These are theoretical air-side forces; the return-spring force reduces the NET usable output. Single-acting pull 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 ATQ Single Acting Thin Cylinder ATQ40X10B Is Used
Gate Retraction
Pulls a diverting gate out of a conveyor lane using the male thread, letting the spring safely extend it to block the flow during an air loss event.
Tension Release
Draws back a belt tensioning idler on exhaust, allowing the internal spring to maintain baseline tension without constant air supply.
Pin Extraction
Releases a locking pin from a machining fixture by retracting the rod, with the fail-safe spring ensuring the pin re-engages if power fails.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ40X10B the Right Cylinder?
For lower force requirements, the 32 mm bore offers a 301.6 N theoretical pull at 0.5 MPa, while the 50 mm bore provides 824.6 N for heavier duty. If your application needs travel beyond 30 mm, switch to a double-acting ACQ. When ordering this unit, verify the 40 mm bore, 10 mm stroke, the male M14x1.5 rod thread, and note the absence of the S magnet option.
Quick checklist
- ✓ Net pull 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 ATQ Single Acting Thin Cylinder ATQ40X10B FAQ
It delivers a theoretical pull of 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa before spring deduction. Operating pressure is 0.2-1.0 MPa minimum to overcome the spring, and the maximum standard stroke for this 40 mm bore is 30 mm.
A fixed NBR elastomer bumper handles end-stop energy, meaning there is no adjustable air cushion. If air is lost, the internal spring automatically extends the rod to its outward rest position.
