Airtac ATQ Single Acting Thin Cylinder ATQ32X25B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ32X25B is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø32mm bore and 25mm 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 ATQ32X25B
The AirTAC ATQ32X25B is a JIS compact single-acting PULL cylinder, meaning compressed air fed to its single PT1/8 port retracts the 16mm rod, while an internal spring drives the extension stroke upon exhaust. This configuration is ideal for hold-down-release logic where venting the line safely extends the rod to its resting position. It delivers a 301.6N theoretical pull at 0.5 MPa (422.2N at 0.7 MPa) before accounting for the return spring.
Because this specific unit includes the B option, it features a male M14x1.5 piston rod end that couples directly to your mechanism. Deceleration is handled by a fixed NBR elastomer bumper rather than an adjustable air cushion, so for high-energy cycles you should slow the approach or use an external shock absorber. The 25mm stroke stays well within the 30mm maximum travel limit for this bore size.
Airtac ATQ Single Acting Thin Cylinder ATQ32X25B Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ32X25B |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 25 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 ATQ32X25B Is Used
Gate Retraction
Pulls a sorting gate out of the conveyor lane using the 301.6N theoretical air pull, letting the internal spring push it back into the blocking position when air is cut.
Clamp Release
Holds a carton flap down during sealing; venting the PT1/8 port lets the spring extend the rod, lifting the male-threaded clamp arm away safely.
Pin Extraction
Draws a locating pin from a machined fixture on demand, relying on the fail-safe spring to reinsert the pin and secure the workpiece during an air loss.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ32X25B the Right Cylinder?
If 301.6N of theoretical pull is insufficient, stepping up to the 40mm bore yields 527.8N at 0.5 MPa; conversely, dropping to the 25mm bore provides 188.9N for lighter tensioning duties. Should your application require more than the 30mm maximum stroke allowed for this single-acting series, a double-acting ACQ cylinder is the correct choice. When ordering, verify the 32mm bore, 25mm stroke, male M14x1.5 rod thread, and note this unit lacks a magnet (-S) for position sensing.
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 ATQ32X25B FAQ
It provides a 301.6N theoretical pull at 0.5 MPa and 422.2N at 0.7 MPa before the return spring lowers the net output. It requires a minimum 0.2 MPa operating pressure to overcome the spring, has a 25mm stroke (max 30mm for this bore), and uses a PT1/8 port.
Loss of air pressure causes the internal spring to extend the rod to its rest position. At each end of the body, a fixed NBR elastomer bumper absorbs end-of-stroke impact; it is not an adjustable air cushion, so high-speed approaches may need external shock absorption.
