Airtac ATQ Single Acting Thin Cylinder ATQ20X15S
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ20X15S is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø20mm 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 ATQ20X15S
The AirTAC ATQ20X15S is a JIS compact single-acting pull cylinder where supplying air to one port retracts the 10mm rod, while an internal spring drives the extension. It delivers a theoretical pull of 117.8N at 0.5MPa (164.9N at 0.7MPa) before spring deduction; verify the lower net output via the official datasheet.
Featuring a built-in magnet, this unit operates reliably with either reed or solid-state electronic switches. The fixed TPU elastomer bumper absorbs end-of-stroke impact, and the single-air-line design simplifies plumbing while ensuring the rod automatically extends to its rest position upon loss of air pressure.
Airtac ATQ Single Acting Thin Cylinder ATQ20X15S Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ20X15S |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø20 mm |
| Stroke | 15 mm |
| Acting type | Single acting, pull type |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø20mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 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 ATQ20X15S Is Used
Pin Extraction
Pulls locating pins out of machining fixtures during automated part unloading cycles.
Gate Retraction
Draws back diverter gates on packaging lines to release cartons down the sorting lane.
Tension Release
Releases tension on web materials in printing machinery by retracting an idler roller.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ20X15S the Right Cylinder?
When sizing this 20mm bore actuator, compare its 117.8N theoretical pull at 0.5MPa against the 75.4N of a 16mm bore or the 188.9N of a 25mm bore version. This 15mm stroke sits well below the 30mm maximum limit for this diameter; for longer travel requirements, transition to a double-acting ACQ cylinder. To finalize your order, confirm the 15mm stroke, the S magnet option, and the default female M5x0.8 rod-end thread.
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 ATQ20X15S FAQ
It provides a theoretical pull of 117.8N at 0.5MPa and 164.9N at 0.7MPa before the return spring lowers the net output. Operating pressure is 0.2-1.0MPa (0.2MPa minimum to overcome the spring), speed is 50-500mm/s, and maximum standard stroke for this bore is 30mm.
If air pressure is lost, the internal spring automatically extends the rod to its resting position, ideal for hold-down-release logic. Impact at stroke ends is dampened by a fixed TPU elastomer bumper, which is non-adjustable and may require external shock absorbers for high-energy loads.
