Airtac ACQD Double Acting Compact Cylinder ACQD12X20SB
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X20SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm bore and 20mm 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 ACQD12X20SB
The AirTAC ACQD12X20SB is a double-acting JIS compact cylinder featuring a 12mm bore and 20mm stroke. A Ø6mm piston rod protrudes from both ends, creating identical annular areas. This yields perfectly equal push and pull forces of 42.4N at 0.5MPa and 59.4N at 0.7MPa, ensuring symmetric performance in both directions.
The twin rods inherently resist rotation and extend guide length, eliminating the need for an external anti-rotation guide. It includes a male M5x0.8 rod-end thread for direct coupling, an M5x0.8 port, and a fixed TPU elastomer bumper at each end. The -S magnet enables position sensing with reed or solid-state switches, while the second rod end can drive a sensor flag or secondary load.
Airtac ACQD Double Acting Compact Cylinder ACQD12X20SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD12X20SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 20 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 ACQD12X20SB Is Used
Twin-Guided Pick & Place
Ideal for small electronic component transfer where the dual rods prevent platform twist during high-speed vertical placement.
Symmetric Transfer Unit
Provides equal force extending and retracting a light packaging clamp, ensuring consistent grip pressure on both strokes.
Dual-Station Actuation
The second rod end drives a sensor flag on a PCB testing machine while the primary side handles the test probe.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X20SB the Right Cylinder?
At 0.5MPa this 12mm bore generates 42.4N both ways; sizing down is not available, but stepping up to a 16mm bore raises force to 75.4N. Choose a single-rod ACQ if your application only requires one-sided actuation, or a guided TACQ cylinder if carrying heavy lateral loads. This ACQD12X20SB configuration includes the -S magnet and -B male M5x0.8 rod thread, with a standard 50mm maximum stroke for this bore.
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 ACQD12X20SB FAQ
It delivers an 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 rod occupies both chambers. The standard stroke limit for a 12mm bore is 50mm.
The twin rods resist rotation and provide a longer guide length without needing external guides. It uses fixed TPU elastomer bumpers at both ends for deceleration; these are not adjustable, so external shock absorbers are recommended for high-energy loads.
