Airtac ATQ Single Acting Thin Cylinder ATQ63X25B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X25B is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø63mm 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 ATQ63X25B
The AirTAC ATQ63X25B is a single-acting PULL-type compact cylinder where air driven into the PT1/4 port retracts the Ø20 mm rod, while an internal spring drives the extension stroke. It delivers a theoretical pull force of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa before spring deduction; verify the reduced net output via the official datasheet. This unit features a male M18x1.5 rod-end thread (-B) for direct load coupling.
Designed for short-stroke automation, this 25 mm travel model operates within a 0.2-1.0 MPa pressure range and moves at 50-500 mm/s. Instead of adjustable pneumatic cushions, it relies on a fixed NBR elastomer bumper at the end caps to soften impact. The body includes machined grooves for mounting reed or solid-state sensors, though this specific SKU ships without the internal magnet required for switching.

| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø63mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 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 ATQ63X25B Is Used
Heavy Pin Extraction
Retracts thick locating pins or heavy dowels in large jig and fixture assemblies, utilizing the robust 1962.2 N theoretical pull before spring subtraction.
Pallet Gate Retraction
Pulls a heavy mechanical stop or diverter gate out of the path on heavy-duty material handling lines, allowing loaded pallets to pass safely.
Press Tensioning
Draws a tensioning arm or clamping jaw backward against a mechanical stop in metal forming machinery, releasing the workpiece upon air exhaustion.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X25B the Right Cylinder?
Selecting this 63 mm bore provides the highest theoretical pull capacity in the ATQ family. If your application requires less force, dropping down to the 50 mm bore yields 824.6 N of theoretical pull at 0.5 MPa. Because this is a single-acting spring-return design, the maximum standard stroke is capped at 30 mm; any requirement for longer travel necessitates moving to the double-acting ACQ series. When ordering, confirm the 25 mm stroke, the male M18x1.5 rod thread, and whether your control system needs the -S magnet option 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 ATQ63X25B FAQ
The theoretical pull force is 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, calculated before deducting the return spring. The internal spring extends the rod when air is exhausted, lowering the net output, so confirm exact figures from the datasheet. Operating pressure ranges from 0.2 to 1.0 MPa, and the maximum standard stroke for this bore is 30 mm.
Upon loss of air pressure, the internal spring automatically extends the rod to its resting position, providing a fail-safe release for tensioned loads. To manage kinetic energy at the stroke ends, the cylinder uses a fixed NBR elastomer bumper rather than an adjustable air cushion; for high-speed cycles, consider adding external shock absorbers.
