Airtac ATQ Single Acting Thin Cylinder ATQ40X30
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ40X30 is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø40mm bore and 30mm 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 ATQ40X30
The AirTAC ATQ40X30 is a JIS compact single-acting PULL cylinder, meaning compressed air fed into its single PT1/8 port retracts the 16mm rod, while an internal spring extends it when air is exhausted. This fail-safe extend behavior is ideal for hold-down-release or tensioning tasks where losing pressure safely returns the rod to its outward rest position. Theoretical air-side pull force is 527.8N at 0.5MPa and 738.9N at 0.7MPa before spring loss; verify the exact net output via the official datasheet.
Featuring a 40mm bore and a 30mm stroke (the maximum standard travel for this bore size), this unit uses a fixed NBR elastomer bumper at its ends rather than an adjustable air cushion. The body includes standard magnetic-switch grooves, though this specific configuration ships without the internal magnet. Operating pressure spans 0.2-1.0 MPa, requiring a 0.2 MPa minimum to overcome the return spring, with operational speeds of 50-500 mm/s across a -20 to +70 C temperature range.

| 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.

Where the Airtac ATQ Single Acting Thin Cylinder ATQ40X30 Is Used
Withdrawal Pin Extraction
Uses the powered retract stroke to pull a locator pin out of a machined jig, allowing the spring to safely re-engage the pin into its locked outward position during an air loss.
Gate Retraction
Pulls a compact diverter gate out of a packaging line path; the spring-extend fail-safe ensures the barrier pops back up to block flow when the air supply is shut off.
Clamp Tensioning
Draws a tensioning arm backward against a spring load to hold webbing or wire taut, releasing the tension instantly when the single solenoid exhausts the chamber.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ40X30 the Right Cylinder?
If your application requires slightly less theoretical pull force, the adjacent ATQ32X30 offers 301.6N at 0.5MPa, whereas stepping up to the ATQ50X30 provides 824.6N at 0.5MPa for heavier tensioning demands. Because 30mm is the maximum standard single-acting stroke for this 40mm bore, any application needing longer travel must switch to a double-acting ACQ cylinder. When ordering, verify your required stroke is 30mm or less, select the S option if you need a sensor magnet for reed or solid-state switches, and confirm the default female M8x1.25 rod-end thread suits your mounting hardware.
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 ATQ40X30 FAQ
It delivers a theoretical pull force of 527.8N at 0.5MPa and 738.9N at 0.7MPa before spring reduction (confirm net force from the datasheet). The single-acting spring-extend stroke is 30mm, and operating pressure is 0.2-1.0 MPa, requiring a 0.2 MPa minimum to overcome the return spring.
It relies on a fixed NBR elastomer bumper at each end to absorb impact rather than an adjustable air cushion, so for high-energy loads you should slow the approach or add external shock absorption. If air pressure is lost, the internal spring forces the rod to its extended outward rest position.
