Airtac ATQ Single Acting Thin Cylinder ATQ40X5
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ40X5 is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø40mm bore and 5mm 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 ATQ40X5
The AirTAC ATQ40X5 is a single-acting PULL-type compact cylinder where air supplied to one port retracts the 16 mm rod, while an internal spring drives the extension stroke. It delivers a 527.8 N theoretical pull at 0.5 MPa (738.9 N at 0.7 MPa) before spring deduction; verify the exact net output via the official datasheet. This 40 mm bore unit operates between 0.2 and 1.0 MPa.
Designed for short 5 mm travel, this JIS-format actuator features a fixed NBR elastomer bumper at its ends to soften end-of-stroke impacts rather than relying on adjustable air cushions. The body includes machined grooves for mounting reed or solid-state sensors, though this specific configuration ships without a magnet. Loss of pneumatic pressure causes the spring to extend the rod automatically, providing a fail-safe return for tensioning or hold-down-release tasks.
Airtac ATQ Single Acting Thin Cylinder ATQ40X5 Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ40X5 |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 5 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.

Where the Airtac ATQ Single Acting Thin Cylinder ATQ40X5 Is Used
Pin Extraction
Retracts a locking pin on an automated machining center fixture, using the spring to push the pin back into the locked position during power loss.
Gate Retraction
Pulls a diverter gate closed on a packaging conveyor line, allowing the internal spring to extend and open the lane when air is exhausted.
Tension Control
Draws back a tensioning arm on a wire winding machine, maintaining steady tension via the spring-extended rest state.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ40X5 the Right Cylinder?
Choosing this 40 mm bore involves balancing the 527.8 N theoretical pull against the load; stepping down to a 32 mm bore drops the 0.5 MPa pull to 301.6 N, whereas a 50 mm bore raises it to 824.6 N. If your mechanism requires travel beyond the 30 mm single-acting maximum, switch to the double-acting ACQ series. When ordering the ATQ40X5, confirm the 5 mm stroke, PT1/8 port, and default female M8x1.25 rod end.
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 ATQ40X5 FAQ
It provides a 527.8 N theoretical pull at 0.5 MPa and 738.9 N at 0.7 MPa before the return spring is factored in. It requires a minimum operating pressure of 0.2 MPa to overcome the spring, has a 5 mm stroke, and supports a 30 mm maximum standard stroke for this bore.
If air pressure is lost, the internal spring automatically extends the rod to its resting position. To manage impact energy at the stroke ends, the cylinder uses a fixed NBR elastomer bumper instead of an adjustable air cushion.
