Airtac ACQD Double Acting Compact Cylinder ACQD12X50
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X50 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm bore and 50mm 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 ACQD12X50
The AirTAC ACQD12X50 is a double-acting JIS compact cylinder featuring a 12mm bore and 50mm stroke, which is the maximum standard stroke for this size. A 6mm piston rod extends from both ends, creating an identical annular area on each side. This geometry yields perfectly equal push and pull forces of 42.4N at 0.5 MPa and 59.4N at 0.7 MPa, ensuring symmetric performance in both directions.
Because the twin rods resist rotation and provide a longer guide length, you can mount a small tool platform directly without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. This 50-stroke unit uses an M5x0.8 port and fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration. It ships without a magnet, though the body retains magnetic-switch grooves for future sensing upgrades.
Airtac ACQD Double Acting Compact Cylinder ACQD12X50 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD12X50 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 50 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 ACQD12X50 Is Used
Twin-Guided Component Pusher
Pushs small electronic parts in an assembly line using both rod ends to maintain strict alignment and prevent platform twist without external guides.
Symmetric Transfer Arm
Moves lightweight items between two processing stations where the equal 42.4N push and pull forces ensure consistent placement in both directions.
Dual-Station Pick & Place
Drives a small pick-and-place head on a packaging machine, using the opposing rod end to mount a physical sensor flag for position confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X50 the Right Cylinder?
Select this 12mm bore when your application requires exactly 42.4N of force at 0.5 MPa in both directions across a 50mm travel. If your push or pull requirement is lower, note that this is the smallest available bore in the series, so you would need to throttle the air supply or explore a single-rod ACQ variant if unequal forces are acceptable. For higher loads, stepping up to the 16mm bore provides 75.4N at 0.5 MPa. This specific model features a female M3x0.5 rod-end thread and standard PT port threading. Confirm you only need 50mm of stroke, as exceeding this requires a non-standard configuration.
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 ACQD12X50 FAQ
The ACQD12X50 delivers an equal push and pull force of 42.4N at 0.5 MPa and 59.4N at 0.7 MPa, with a maximum capacity of 9 kgf at 1.0 MPa. Because the rod exits both ends, the annular area is identical in each direction, making the forces perfectly symmetric. The maximum standard stroke for this 12mm bore is 50mm.
No, it uses fixed TPU elastomer bumpers at both ends for deceleration, not adjustable air cushions. Additionally, while the body features magnetic-switch grooves, this specific model ships without a -S sensor magnet. Also, note that a plain ACQ cylinder does not hold its load on air loss; you must add an external rod lock or pilot check valve for fail-safe holding.
