Airtac ATQ Single Acting Thin Cylinder ATQ20X20B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ20X20B 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 ATQ20X20B
The AirTAC ATQ20X20B is a JIS compact single-acting pull cylinder. Feeding air to the single M5x0.8 port retracts the 10mm rod, while an internal spring extends it upon exhaust. This fail-safe design ensures the rod extends to its rest position if air pressure drops, which is ideal for hold-down-release or tensioning tasks. The unit delivers a 117.8N theoretical pull at 0.5 MPa (164.9N at 0.7 MPa) before spring resistance lowers the net output.
This 20mm bore configuration features a 20mm stroke within the 30mm maximum limit for this bore size. It includes a male M8x1.25 rod-end thread for direct load coupling. A fixed TPU elastomer bumper absorbs end-of-stroke impact, and the body retains magnetic-switch grooves, though this specific SKU ships without a magnet.
Airtac ATQ Single Acting Thin Cylinder ATQ20X20B Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ20X20B |
|---|---|
| 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.

Thread: PT standard (G / NPT available). ASQ pushes out / spring returns; ATQ pulls in / spring extends. Related: ACQ (double acting), ACQD (double rod), ACQJ (adjustable stroke).
Where the Airtac ATQ Single Acting Thin Cylinder ATQ20X20B Is Used
Pin Extraction
Pulls locating pins out of a fixture during automated machining or assembly processes.
Gate Retraction
Withdraws a pneumatic stop gate to release workpieces down a packaging line.
Tensioning Mechanism
Draws back a belt or cable tensioner, using the spring to maintain baseline tension.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ20X20B the Right Cylinder?
For lower force requirements, the 16mm bore offers a 75.4N theoretical pull at 0.5 MPa, while the 25mm bore provides a 188.9N theoretical pull for heavier retraction. If your application requires travel beyond the 30mm maximum single-acting stroke, select the double-acting ACQ series instead. When ordering the ATQ20X20B, verify the 20mm stroke, the male M8x1.25 rod thread, and the M5x0.8 port size.
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 ATQ20X20B FAQ
It provides a 117.8N theoretical pull at 0.5 MPa and 164.9N at 0.7 MPa before the return spring lowers the net output. It is a single-acting pull type with a 20mm stroke (max 30mm), requires a 0.2 MPa minimum operating pressure, and functions at 0.2-1.0 MPa.
The internal spring extends the rod to its resting position when air is exhausted, ensuring a fail-safe extend. A fixed TPU elastomer bumper handles end-stop impact; this is not an adjustable air cushion, so external shock absorption may be needed for high-energy cycles.
