Airtac ACQD Double Acting Compact Cylinder ACQD12X40
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X40 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm bore and 40mm 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 ACQD12X40
The AirTAC ACQD12X40 is a double-acting JIS compact cylinder featuring a 12mm bore and 40mm stroke. A 6mm piston rod extends from both body ends, creating identical annular areas. This yields an equal 42.4N force at 0.5MPa in both push and pull directions, ensuring perfectly symmetric cycle performance.
The dual-rod architecture resists torsion and extends guide length, allowing a small tool platform to be carried without a separate anti-rotation guide. The second rod tip can drive a sensor flag or a secondary load. It features fixed TPU bumpers at both ends for end-of-stroke deceleration, M5x0.8 pneumatic ports, and female M3x0.5 rod-end threads.
Airtac ACQD Double Acting Compact Cylinder ACQD12X40 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD12X40 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 40 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 ACQD12X40 Is Used
Twin-Guided Pick & Place
Handles delicate electronic components in pick-and-place heads where the twin rods prevent chuck rotation during rapid vertical shifts.
Symmetric Transfer Unit
Drives a small parts shuttle across a packaging conveyor, using the equal push and pull forces to maintain stable timing in both directions.
Dual-Station Actuation
Powers a compact testing jig where the rear rod end mounts a mechanical flag to trip an external limit switch at mid-stroke.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X40 the Right Cylinder?
For 42.4N bidirectional thrust, this 12mm bore is the smallest available; stepping up to a 16mm bore provides 75.4N if your payload requires more force. Because this specific unit lacks the -S magnet, it cannot trigger reed or solid-state sensors despite having body grooves; add the -S suffix if position detection is needed. Confirm female M3x0.5 rod threads and PT porting 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 ACQD12X40 FAQ
It generates 42.4N at 0.5MPa and 59.4N at 0.7MPa, with a maximum of 9kgf at 1.0MPa. Push and pull forces are equal because the 6mm rod occupies both chambers. The standard stroke limit is 50mm, operating pressure is 0.15-1.0MPa, and speed is 30-500mm/s.
It uses fixed TPU elastomer bumpers at both ends for impact absorption, not adjustable air cushions. A plain ACQD does not hold position when air is lost; the rod drifts. For fail-safe load holding, an external rod lock or pilot-operated check valve is required.
