Airtac ACQD Double Acting Compact Cylinder ACQD12X25B
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X25B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm bore and 25mm 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 ACQD12X25B
The AirTAC ACQD12X25B is a double-acting JIS compact cylinder featuring a rod exiting both ends. Because a piston rod occupies each chamber, the annular area remains identical in both directions, giving exactly 42.4N of force at 0.5MPa and 59.4N at 0.7MPa on both push and pull strokes. This symmetry eliminates force mismatch during bidirectional tasks.
The twin 6mm rods resist rotation and extend the guide length, allowing a small tool platform to travel accurately without needing an external guide rail. The body includes magnetic-switch grooves for repositionable sensors, although this specific unit ships without a magnet. A fixed TPU elastomer bumper at each end handles end-of-stroke deceleration, and the male M5x0.8 rod-end thread couples directly to your load.
Airtac ACQD Double Acting Compact Cylinder ACQD12X25B Technical Specifications

| Bore size | Ø12 mm |
| Stroke | 25 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 50 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 (Ø12mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 42 N | 42 N |
| 0.7 MPa | 59 N | 59 N |
| Max (@1.0 MPa) | 9 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 ACQD12X25B Is Used
Symmetric Transfer
Drives a small electronic component shuttle across a PCB assembly line, using the equal push and pull force to maintain consistent timing in both directions.
Twin-Guided Pusher
Ejects small stamped metal parts from a press die without rotating the tooling plate, relying on the dual rods for inherent anti-rotation stability.
Dual-Station Actuation
Actuates a tiny clamping fixture on a semiconducter wafer handler, using the second rod end to drive a mechanical flag for a home position.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X25B the Right Cylinder?
For 12mm bore, this double-rod unit provides 42.4N of equal force both ways. If your application needs less force, the series lacks a smaller standard bore, so you would rely on flow controls or pressure regulation to scale down. If higher thrust is required, stepping up to the 16mm bore raises the output to 75.4N at 0.5MPa. Choose this specific ACQD12X25B variant when you need the male M5x0.8 rod thread for direct mounting and do not require a sensor magnet. If your task only needs one-sided actuation, a single-rod ACQ cylinder offers a more compact footprint, while a guided TACQ is better for heavy lateral loads. Confirm your 25mm stroke and M5x0.8 port requirements when ordering.
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 ACQD12X25B FAQ
It delivers an equal push and pull force of 42.4N at 0.5MPa and 59.4N at 0.7MPa, with a maximum thrust of 9kgf at 1.0MPa. Push and pull forces are identical because the rod occupies both chambers, making the effective annular area the same in each direction. The maximum standard stroke for a 12mm bore is 50mm.
A plain ACQD does not hold its position upon air loss; the rod drifts and you must add an external rod lock or pilot check valve for fail-safe holding. For deceleration, it uses a fixed TPU elastomer bumper at each end rather than an adjustable air cushion, so high-speed applications may require external shock absorbers or a slowed approach.
