Airtac ATQ Single Acting Thin Cylinder ATQ63X25S
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X25S 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 ATQ63X25S
The ATQ63X25S is a 63mm bore JIS compact cylinder engineered for single-acting PULL operation. Supplying air to the single PT1/4 port retracts the Ø20mm rod, while exhausting the line allows an internal spring to extend it. This makes the unit ideal for holding tension and releasing it upon air loss. Theoretical pull force is 1401.5N at 0.5MPa and 1962.2N at 0.7MPa before spring deduction.
Because the return spring absorbs some energy, verify the exact net output from the official datasheet for your specific load. This 25mm travel model features a built-in magnet for position sensing and a fixed NBR elastomer bumper to soften end-of-stroke impacts. Operating pressure begins at 0.2MPa to overcome the spring, with a maximum standard stroke limit of 30mm for this bore size.

| Stroke | 25 mm |
| Acting type | Single acting, pull type |
| 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 ATQ63X25S Is Used
Tension Release Mechanism
Maintains cable or belt tension in packaging machinery, retracting the rod to slacken the line when compressed air is applied.
Clamp Retraction
Pulls a holding clamp back on an automotive assembly line, utilizing the spring-extend design to safely release the part if air pressure drops.
Diverter Gate Pull
Draws a sorting gate out of the path on a logistics conveyor, relying on the internal spring to push the gate back into blocking position upon exhaust.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X25S the Right Cylinder?
For lighter duty, the 50mm bore version offers a 824.6N theoretical pull at 0.5MPa, whereas this 63mm unit provides 1401.5N. If your mechanism requires travel beyond the 30mm maximum for single-acting models, a double-acting ACQ cylinder is necessary. When ordering this configuration, confirm the 25mm stroke, the S magnet option, and the default female M10x1.5 rod-end thread.
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 ATQ63X25S FAQ
It delivers a theoretical pull of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa before spring deduction. The internal spring extends the rod on exhaust, so net force is lower. Operating pressure is 0.2-1.0MPa, and maximum standard stroke is 30mm.
Loss of air pressure causes the internal spring to automatically extend the rod to its resting position. End-of-stroke impacts are softened by a fixed NBR elastomer bumper, which is non-adjustable and may require external shock absorption for very high speeds.
