Airtac ATQ Single Acting Thin Cylinder ATQ12X15B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ12X15B is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø12mm bore and 15mm 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 ATQ12X15B
The AirTAC ATQ12X15B is a single-acting pull-type JIS compact cylinder where supplying air to one M5x0.8 port retracts the 6mm rod, while an internal spring drives the extension stroke. At 0.5 MPa it provides a 42.4 N theoretical pull (59.4 N at 0.7 MPa) before spring deduction, so verify the net output against your datasheet for precise loading. This 15mm travel unit operates between 0.2-1.0 MPa and relies on a fixed TPU elastomer bumper at the ends rather than an adjustable air cushion.
Equipped with a male M5x0.8 rod-end thread (-B), it couples directly to pulling loads. The compact body retains magnetic-switch grooves for position detection, though this specific SKU ships without the internal magnet. If air pressure drops, the spring automatically extends the rod to its rest state, delivering a fail-safe hold-down-release behavior.

| Bore size | Ø12 mm |
| Stroke | 15 mm |
| Acting type | Single acting, pull type |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 20 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 (Ø12mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 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 ATQ12X15B Is Used
Pin Extraction
Retracts a 6mm rod to withdraw locating pins in small jig assemblies, relying on the spring to safely re-engage the pin when air is removed.
Gate Retraction
Pulls a lightweight diverter gate closed on a packaging line, using the 15mm stroke to clear the product path during normal operation.
Gripper Release
Draws a small clamping jaw open against tension in electronics manufacturing, allowing the internal spring to snap the jaw shut for gripping.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ12X15B the Right Cylinder?
Choosing this 12mm bore involves balancing your required pulling force against the 42.4 N theoretical rating at 0.5 MPa; dropping to a smaller bore is not an option as 12mm is the minimum, but stepping up to the 16mm bore raises the theoretical pull to 75.4 N. This 15mm stroke fits well within the 20mm maximum single-acting limit for this bore, yet any application needing longer travel must switch to the double-acting ACQ series. When ordering, confirm the 12mm bore, 15mm stroke, male M5x0.8 rod thread, and note that no -S magnet is installed.
Quick checklist
- ✓ Net pull force (after spring) at your pressure
- ✓ Stroke ≤ 20 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 ATQ12X15B FAQ
It delivers a 42.4 N theoretical pull at 0.5 MPa and 59.4 N at 0.7 MPa before the return spring is factored in, requiring a minimum operating pressure of 0.2 MPa. The maximum standard stroke for the 12mm bore is 20mm, and this 15mm variant safely operates within that single-acting travel range.
Because it is a pull-type design, exhausting the air causes the internal spring to extend the rod outward to its rest position, which is ideal for hold-down-release logic. Deceleration is handled by a fixed TPU elastomer bumper rather than an adjustable cushion, so external shock absorbers may be needed for high-energy cycles.
