Airtac ATQ Single Acting Thin Cylinder ATQ32X20B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ32X20B 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 ATQ32X20B
The AirTAC ATQ32X20B is a single-acting pull-type JIS compact cylinder. Supplying air to the single PT1/8 port retracts the Ø16 mm rod, while an internal spring extends it upon exhaust. This fail-safe behavior ensures the rod moves to its extended rest position if air pressure drops. The unit delivers a 301.6 N theoretical pull at 0.5 MPa (422.2 N at 0.7 MPa) before accounting for the return spring, which lowers the net output force.
Featuring a 20 mm stroke within the 30 mm maximum limit for this bore, the riveted body incorporates a fixed NBR elastomer bumper at each end to soften impact. This specific configuration includes a male M14x1.5 rod-end thread for direct load coupling. Although the body retains magnetic-switch grooves, this variant ships without a piston magnet, so external reed or solid-state sensors will not function without modification.

| Stroke | 20 mm |
| Acting type | Single acting, pull type |
| 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 ATQ32X20B Is Used
Tension Release Mechanism
Ideal for pulling a tensioning pin out of a web-guide assembly on packaging machinery, using the spring to safely re-engage the pin when air is removed.
Retractable Package Stop
Draws back a physical gate on a sorting line to let cartons pass, relying on the internal spring to snap the stop back into place during a pneumatic outage.
Clamp Release Actuator
Releases a holding clamp on a machining fixture by retracting the male-thread rod, allowing the spring to maintain clamping pressure in the default state.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ32X20B the Right Cylinder?
For lower force requirements, the adjacent ATQ25 model offers a 188.9 N theoretical pull at 0.5 MPa. If your application demands greater power, stepping up to the ATQ40 bore provides a 527.8 N theoretical pull at the same 0.5 MPa. Since this 20 mm stroke falls under the 30 mm single-acting limit, it fits perfectly here; travels exceeding 30 mm require the double-acting ACQ series. When ordering, verify the 32 mm bore, 20 mm stroke, male M14x1.5 rod thread, and the absence of a magnet (-S).
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 ATQ32X20B FAQ
It provides a 301.6 N theoretical pull at 0.5 MPa and 422.2 N at 0.7 MPa before the return spring reduces net output. The internal spring extends the rod on exhaust. Operating pressure is 0.2-1.0 MPa (0.2 MPa minimum to overcome the spring), and the stroke is 20 mm, which is under the 30 mm maximum for this 32 mm bore.
A fixed NBR elastomer bumper at each end absorbs impact energy; it is not an adjustable air cushion. If air pressure is lost, the fail-safe design uses the internal spring to automatically extend the rod to its resting position, which is optimal for hold-down-release logic.
