Airtac ATQ Single Acting Thin Cylinder ATQ63X25
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X25 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 ATQ63X25
The AirTAC ATQ63X25 is a JIS compact single-acting pull cylinder. Supplying air to the single PT1/4 port retracts the 20mm rod, while an internal spring extends it upon exhaust. It delivers a theoretical pull force of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa before spring deduction. The return spring lowers net output, so confirm exact figures from the datasheet.
Designed for a 25mm stroke within a 30mm maximum limit, this 63mm bore actuator features a fixed NBR elastomer bumper at each end. It requires a 0.2MPa minimum operating pressure to overcome the spring. The body includes standard magnetic-switch grooves, though this specific configuration ships without a magnet. Loss of air causes the spring to extend the rod outward to its rest position, providing inherent fail-safe tensioning logic.
Airtac ATQ Single Acting Thin Cylinder ATQ63X25 Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ63X25 |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø63 mm |
| 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 ATQ63X25 Is Used
Injection Mold Plunger Extraction
Pulls an internal mold plunger back against the spring to release injection-molded plastic parts, automatically extending outward to reset the core when the air supply stops.
Heavy Package Diverter Arm
Retracts a heavy routing gate on a logistics conveyor to let large boxes pass, using the high theoretical pull force to overcome significant mechanical friction.
Film Roll Tensioning
Draws a tensioning idler back during packaging film feeds, where the spring-extend rest position maintains constant outward pressure for material tracking.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X25 the Right Cylinder?
For sizing within the 12-63mm bore range, dropping to a 50mm bore yields a 824.6N theoretical pull at 0.5MPa, while 63mm is the largest available. If your application requires a stroke longer than 30mm, you must switch to the double-acting ACQ series. When ordering, verify the 63mm bore, 25mm stroke, female M10x1.5 rod-end thread, and note that the -S magnet option is omitted here.
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 ATQ63X25 FAQ
It provides a theoretical pull of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa before spring deduction. The maximum standard stroke is 30mm, and it requires a 0.2MPa minimum operating pressure to overcome the internal return spring.
If air is lost, the internal spring automatically extends the rod outward to its rest position. It uses a fixed NBR elastomer bumper at the end caps to absorb impact, which is not an adjustable air cushion or brake.
