Airtac ACQD Double Acting Compact Cylinder ACQD12X25
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X25 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 ACQD12X25
The AirTAC ACQD12X25 is a double-acting JIS compact cylinder featuring a 12mm bore and 25mm stroke. A Ø6mm piston rod protrudes from both ends, creating identical annular areas. This yields perfectly balanced thrust, giving you 42.4N of force at 0.5MPa and 59.4N at 0.7MPa in both directions. The twin-rod layout resists torsion and lengthens guide support without needing an external guide.
Built with a fixed TPU elastomer bumper at each end, it decelerates the load near stroke limits but is not an adjustable air cushion. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet. Operating on M5x0.8 PT ports, it handles speeds of 30-500mm/s. Note that a plain double-rod cylinder drifts when air is lost; secure external rod locks for fail-safe holding.
Airtac ACQD Double Acting Compact Cylinder ACQD12X25 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD12X25 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| 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 ACQD12X25 Is Used
Twin-Guided Pick & Place
Drives a small pneumatic gripper on an electronics assembly line, using the dual rods to prevent jaw rotation during precise component placement.
Symmetric Transfer Pusher
Indexes lightweight product cartons between conveyor belts, benefiting from the identical 42.4N push and pull force for consistent bi-directional cycling.
Dual-Station Lab Actuator
Moves a fluid dispensing valve between two test vials, using the second rod end to mount a physical travel flag for external confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X25 the Right Cylinder?
For 12mm bore sizing, this ACQD12X25 provides 42.4N symmetric thrust. If your application needs less force, the series does not offer a smaller bore, so you would rely on lowering pressure. Stepping up to the 16mm bore raises the equal push and pull force to 75.4N at 0.5MPa. If you only require one-sided actuation and unequal thrust (where push exceeds pull), a single-rod ACQ cylinder is a better fit. Confirm your ordering essentials: this unit uses a female M3x0.5 rod-end thread and a standard 25mm stroke within the 50mm maximum limit.
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 ACQD12X25 FAQ
The ACQD12X25 provides equal push and pull force of 42.4N at 0.5MPa and 59.4N at 0.7MPa, with a maximum of 9kgf at 1.0MPa. Push and pull are equal because the twin rods occupy both chambers, creating matching annular areas. The maximum standard stroke for this 12mm bore is 50mm.
No, a plain ACQD does not hold position upon air loss; the rod drifts and the fixed TPU bumper only decelerates near the stroke end. For fail-safe load holding, you must add an external rod lock or a pilot-operated check valve.
