Airtac ATQ Single Acting Thin Cylinder ATQ12X15S
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ12X15S 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 ATQ12X15S
The AirTAC ATQ12X15S is a single-acting PULL-type JIS compact cylinder where supplying air to one port retracts the rod, while an internal spring extends it upon exhaust. It yields a theoretical pull of 42.4 N at 0.5 MPa (59.4 N at 0.7 MPa) before the return spring lowers net output. You should confirm the exact net force from the official datasheet for your setup.
Featuring a 6 mm piston rod and an M5x0.8 port, this 12 mm bore unit requires a 0.2 MPa minimum operating pressure to overcome the spring. It uses a fixed TPU elastomer bumper for end-of-stroke damping rather than an adjustable air cushion. The built-in magnet (-S) works with reed or solid-state switches in the body grooves, and the 15 mm stroke stays well under the 20 mm maximum travel for this bore.

| 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 ATQ12X15S Is Used
Withdrawal Pin Extraction
Ideal for pulling a locating pin out of a jig on automated machining centers using the spring-extend fail-safe return.
Gate Stopper Retraction
Pulls a pneumatic stopper gate back to release packaged goods down a packaging line when pressurized.
Tensioning Arm Release
Draws a light tensioning arm backward to release web materials in a printing or converting machine.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ12X15S the Right Cylinder?
For slightly less force, the next size down is unavailable as 12 mm is the smallest bore. To step up, the 16 mm bore raises the theoretical pull to 75.4 N at 0.5 MPa. If your application needs a longer travel distance than the 20 mm maximum single-acting limit, you should switch to the double-acting ACQ series. When ordering, verify the 12 mm bore, 15 mm stroke, the -S magnet option, and the default female M3x0.5 rod-end thread.
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 ATQ12X15S FAQ
The theoretical pull is 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa before the return spring lowers net output. It requires a 0.2 MPa minimum operating pressure, uses a 15 mm stroke, and the maximum standard stroke for a 12 mm bore is 20 mm.
Because it is a single-acting pull type, exhausting the air lets the internal spring extend the rod to its rest position. End-of-stroke damping is handled by a fixed TPU elastomer bumper, not an adjustable air cushion, so external shock absorbers may be needed for high-energy loads.
