Airtac ATQ Single Acting Thin Cylinder ATQ20X20
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ20X20 is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø20mm bore and 20mm 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 ATQ20X20
The AirTAC ATQ20X20 is a single-acting PULL-type JIS compact cylinder. Supplying air to its single M5x0.8 port retracts the 10mm rod, while an internal spring extends it upon exhaust. It delivers a theoretical pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa before spring deduction. The return spring lowers the net output, which must be confirmed from the datasheet for exact loads.
This 20mm bore unit features a fixed TPU elastomer bumper to soften end-of-stroke impacts rather than an adjustable air cushion. Operating pressure spans 0.2-1.0MPa, needing the 0.2MPa minimum to overcome the spring. It ships without a magnet, yet the body retains sensor grooves for adding switches. Loss of air causes a fail-safe extension to the rest position.
Airtac ATQ Single Acting Thin Cylinder ATQ20X20 Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ20X20 |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø20 mm |
| Stroke | 20 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 ATQ20X20 Is Used
Pin Extraction
Pulls locating pins out of machined jigs on automated milling centers using its 164.9N theoretical retract force.
Gate Retraction
Draws back a diverter gate on a packaging line, allowing the internal spring to extend the barrier safely during air loss.
Gripper Release
Releases tension on small robotic grippers holding electronic components, utilizing the 20mm stroke for quick release.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ20X20 the Right Cylinder?
For sizing alternatives within the 12-63mm range, dropping to a 16mm bore yields a 75.4N theoretical pull at 0.5MPa, while stepping up to a 25mm bore provides 188.9N at 0.5MPa. If your application requires a stroke longer than the 30mm maximum for this single-acting pull series, you must switch to the double-acting ACQ cylinder. When ordering this female-thread (M5x0.8) rod model, verify the 20mm stroke, 20mm bore, and port size to ensure compatibility.
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 ATQ20X20 FAQ
It provides a theoretical pull of 117.8N at 0.5MPa and 164.9N at 0.7MPa before spring deduction. It is single-acting with spring-extend, requiring a 0.2-1.0MPa operating pressure. The maximum standard stroke is 30mm.
If air pressure drops, the internal spring forces the rod to the extended rest position. At the end of travel, a fixed TPU elastomer bumper absorbs impact, as there is no adjustable air cushion.
