Airtac ATQ Single Acting Thin Cylinder ATQ32X25
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ32X25 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 ATQ32X25
The AirTAC ATQ32X25 is a JIS compact single-acting PULL cylinder. Feeding air into the single PT1/8 port retracts the 16mm rod, while an internal spring extends it back out upon exhaust. This design is ideal for hold-down-release or tensioning tasks requiring a fail-safe extend position. Theoretical air-side pull force is 301.6N at 0.5MPa and 422.2N at 0.7MPa before spring deduction.
This 32mm bore unit features a fixed NBR elastomer bumper at the stroke ends to soften impact, rather than an adjustable air cushion. Operating pressure spans 0.2-1.0 MPa, needing the 0.2 MPa minimum to overcome the return spring. The 25mm travel stays within the 30mm single-acting limit for this bore size.
Airtac ATQ Single Acting Thin Cylinder ATQ32X25 Technical Specifications

| 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 ATQ32X25 Is Used
Tensioning Clamps
Applies air-driven retraction to pull tensioning cables or straps tight on packaging equipment, using the spring to safely release tension when air is removed.
Retracting Machine Stops
Pulls a physical stop pin out of the way on a CNC conveyor line to let workpieces pass, with the internal spring pushing the stop back up as a fail-safe during pressure loss.
Drawing Alignment Pins
Draws locating pins back beneath a fixture plate on an assembly press, allowing the 16mm rod to pull the pin clear of the part before the spring extends it for the next cycle.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ32X25 the Right Cylinder?
For lighter pull requirements, the 25mm bore version offers a 188.9N theoretical pull at 0.5 MPa. If your application needs greater retraction force, stepping up to the 40mm bore yields 527.8N at 0.5 MPa. Since this is a 25mm stroke within the 30mm single-acting limit, it fits perfectly; travels beyond 30mm require the double-acting ACQ series. When ordering, verify your 32mm bore, 25mm stroke, standard female M8x1.25 rod thread, and note this configuration ships without a magnet.
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 ATQ32X25 FAQ
It provides a theoretical pull of 301.6N at 0.5MPa and 422.2N at 0.7MPa before the return spring is factored in (net output is lower; verify via datasheet). Operating pressure is 0.2-1.0 MPa, requiring a 0.2 MPa minimum to overcome the spring. The maximum standard stroke for this 32mm bore is 30mm.
It uses a fixed NBR elastomer bumper at the ends to absorb impact rather than an adjustable air cushion. Because it is spring-extend, the fail-safe state is the rod extended outward; if air pressure drops completely, the spring pushes the rod to the extended rest position.
