Airtac ACQD Double Acting Compact Cylinder ACQD12X45S
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X45S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm bore and 45mm 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 ACQD12X45S
The AirTAC ACQD12X45S is a double-acting JIS compact cylinder where a rod protrudes from both ends. Because a piston rod occupies each chamber, the annular area is identical on extension and retraction, yielding equal push and pull force of 42.4N at 0.5MPa and 59.4N at 0.7MPa. This symmetry is ideal for cycles requiring identical force in both directions.
The twin rods inherently resist rotation and provide a longer guide length, allowing you to mount a small tool platform directly without needing a separate external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. This 12mm bore unit features a Ø6mm rod, M5x0.8 PT port, and a fixed TPU elastomer bumper at each end for end-of-stroke deceleration.
Airtac ACQD Double Acting Compact Cylinder ACQD12X45S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD12X45S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 45 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 ACQD12X45S Is Used
Twin-Guided Pick & Place
Mounts a small electronic component gripper directly to the rod ends, using the extended guide length to prevent twist during vertical pickup in PCB assembly.
Symmetric Transfer Pusher
Shifts light plastic cassettes back and forth on a conveyor line, relying on the equal 42.4N extension and retraction force for consistent indexing.
Dual-Station Actuation
Drives a tiny stamping head while the opposing rod end simultaneously triggers a solid-state sensor flag on a packaging machine.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X45S the Right Cylinder?
For this 45mm stroke, the 12mm bore provides 42.4N of force both ways; if you need less force, you would drop to a smaller compact body, while stepping up to a 16mm bore yields 75.4N at 0.5MPa. Choose this double-rod ACQD over a single-rod ACQ when symmetric push/pull cycles and anti-rotation are required. The -S suffix confirms the piston magnet is installed for use with reed or solid-state switches. Standard female M3x0.5 rod-end threads and PT porting are supplied.
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 ACQD12X45S FAQ
It delivers 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 equals pull because the twin rods create the same annular piston area in both chambers. The maximum standard stroke available for this 12mm bore is 50mm.
No, a plain ACQD does not hold position on air loss; the rod drifts and the fixed TPU bumper only decelerates near the stroke end. For fail-safe vertical load holding, you must add an external rod lock or a pilot-operated check valve.
