Airtac ATQ Single Acting Thin Cylinder ATQ32X20
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ32X20 is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø32mm 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 ATQ32X20
The AirTAC ATQ32X20 is a single-acting PULL-type compact cylinder where supplying air to the single PT1/8 port retracts the Ø16 mm rod. When exhaust occurs, an internal mechanical spring pushes the tooling back out. This mechanism requires a minimum operating pressure of 0.2 MPa to overcome the spring force.
At 0.5 MPa, this 32 mm bore unit delivers a 301.6 N theoretical pull (422.2 N at 0.7 MPa) before spring deduction. The riveted JIS body incorporates fixed NBR elastomer bumpers to manage end-of-stroke impact, avoiding the bulk of adjustable cushioning. Although this specific configuration lacks a piston magnet, the barrel retains standard sensor grooves for adding external reed or solid-state switches.

| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø32mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 302 N |
| 0.7 MPa | 422 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 ATQ32X20 Is Used
Tension Release Mechanism
Pulls to relieve tension on packaging web materials in continuous processing lines, utilizing the spring-extend to safely slacken the load upon air loss.
Retractable Package Stop
Draws back a physical gate on a conveyor sorting system to release boxed goods, depending on the internal spring to deploy the stop when the air supply is cut.
Clamp Withdrawal
Releases holding pressure on machined aluminum components by retracting the rod, allowing the spring to maintain an open, unloaded rest state between cycles.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ32X20 the Right Cylinder?
If 301.6 N theoretical pull is insufficient, step up to the 40 mm bore (527.8 N at 0.5 MPa). If you require less force, the 25 mm bore provides 188.9 N. This 20 mm stroke is well within the 30 mm maximum limit for this bore. Should your automation task demand longer travel, consider a double-acting ACQ cylinder. When ordering, verify the required stroke, female M8x1.25 rod-end thread, and whether your design needs the -S magnet option.
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 ATQ32X20 FAQ
It is a single-acting pull cylinder with a 20 mm stroke (max standard is 30 mm). The theoretical pull force is 301.6 N at 0.5 MPa and 422.2 N at 0.7 MPa. The internal return spring lowers the net output force, which must be confirmed from the datasheet. It requires a minimum of 0.2 MPa operating pressure to function.
It uses fixed NBR elastomer bumpers at the stroke ends to absorb impact rather than adjustable air cushions. In a fail-safe scenario, losing air pressure causes the internal spring to automatically extend the rod to its outward rest position, ensuring the machine returns to a safe, unloaded state.
