Airtac ACQD Double Acting Compact Cylinder ACQD25X15
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X15 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 15mm stroke. The twin rods resist rotation and give equal push and pull force, so it carries and guides a tool platform without a separate anti-rotation guide.

About the Airtac ACQD Double Acting Compact Cylinder ACQD25X15
The AirTAC ACQD25X15 is a double-acting JIS compact cylinder featuring a twin-rod design where a piston extends from both body ends. Because a rod occupies each chamber, the annular area remains identical in both directions. This yields equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa, enabling perfectly symmetric cycles without force imbalance.
The dual Ø12mm rods resist rotational torque and provide extended guide length, eliminating the need for a separate external anti-rotation guide for small platforms. This 15mm stroke unit uses M5x0.8 ports and fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet. Note that a plain compact cylinder does not hold position on air loss; an external rod lock is required for fail-safe load holding.
Airtac ACQD Double Acting Compact Cylinder ACQD25X15 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X15 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 15 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M6×1.0 female / M10×1.25 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Bumper (both ends) |
| Max standard stroke | Up to 100 mm |
Specifications follow the official AirTAC ACQD datasheet. A rod exits both ends, so both directions use the same annular area. Confirm against the product label before installation.
Theoretical Output Force (Ø25mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 189 N | 189 N |
| 0.7 MPa | 264 N | 264 N |
| Max (@1.0 MPa) | 39 kgf | |
Because a rod occupies both chambers, push and pull forces are EQUAL — the annular area applies in each direction. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQD Double Acting Compact Cylinder ACQD25X15 Is Used
Symmetric Transfer Arms
Drives pick-and-place arms in electronics assembly where equal push and pull forces prevent payload drift during bidirectional transfer strokes.
Twin-Guided Pusher
Positions small machined components on a lathe loader, using the inherent anti-rotation properties of the dual rods to maintain tool alignment.
Dual-Station Actuation
Actuates a sealing head on a vertical packaging machine, using the opposing rod end to mount a sensor flag for stroke confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X15 the Right Cylinder?
For a 25mm bore, the ACQD25X15 provides 188.9N of force both ways at 0.5MPa. Stepping down to a 20mm bore yields 117.8N, while moving up to a 32mm bore provides 301.6N, giving clear sizing steps for your payload. If your application only requires unidirectional pushing, a single-rod ACQ cylinder offers a smaller footprint. If you need precise linear guidance without rotational play over longer spans, a guided TACQ cylinder might fit better. When ordering, confirm the 15mm stroke, the default female M6x1.0 rod-end thread, and standard PT port threading.
Quick checklist
- ✓ Equal force both ways at your pressure
- ✓ Anti-rotation needed (twin rods)?
- ✓ Both rod ends usable for tooling?
- ✓ 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 0.15 – 1.0 MPa operating pressure.
- check Both rods share the load — keep force concentric.
- check Twin rods resist rotation but avoid heavy side load.
- check Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQD Double Acting Compact Cylinder ACQD25X15 FAQ
The ACQD25X15 generates equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa, with a maximum of 39kgf at 1.0MPa. Push and pull are equal because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 25mm bore is 100mm.
The twin-rod construction inherently resists rotation and increases guide length without needing an external guide. End-of-stroke deceleration is handled by fixed TPU elastomer bumpers at both ends, which are not adjustable. The body has sensor grooves, but this model ships without a magnet.
