Airtac ACQD Double Acting Compact Cylinder ACQD20X30S
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X30S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 30mm 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 ACQD20X30S
The AirTAC ACQD20X30S is a double-acting JIS compact cylinder where a 10mm piston rod exits both ends. Because both chambers share the same annular area, it generates identical push and pull thrust of 117.8N at 0.5MPa and 164.9N at 0.7MPa. The twin-rod layout resists torsion and lengthens guide support, letting you mount a small tool platform directly without adding an external anti-rotation guide.
This 20mm bore unit includes a built-in piston magnet (-S) compatible with reed or solid-state electronic switches via its integrated mounting grooves. It features a fixed TPU elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The standard M5x0.8 port and female M5x0.8 rod-end thread simplify pneumatic hookups and tooling attachments for 30mm travel.
Airtac ACQD Double Acting Compact Cylinder ACQD20X30S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X30S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 30 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 100 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 (Ø20mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 118 N | 118 N |
| 0.7 MPa | 165 N | 165 N |
| Max (@1.0 MPa) | 24 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 ACQD20X30S Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place head in electronics assembly, using the equal push/pull force to maintain balanced positioning during component placement.
Twin-Guided Pusher
Ejects machined parts on an automated lathe, relying on the twin rods to prevent platform twisting under offset loads without needing an external guide rail.
Dual-Station Actuation
Powers a secondary tooling flag or small secondary load from the opposite rod end on a packaging machine, synchronizing two processes with one compact actuator.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X30S the Right Cylinder?
Providing 117.8N of symmetric thrust, this 20mm bore sits neatly between the smaller 16mm bore (75.4N) and the larger 25mm bore (188.9N) at 0.5MPa. Choose this size when your application requires matched push/pull cycles within a compact footprint. If your mechanism only needs one-sided actuation, the single-rod ACQ series saves space; if you need higher side-load capacity, consider a guided TACQ cylinder. When ordering, confirm the 30mm stroke, the -S magnet option, and the default female M5x0.8 rod thread.
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 ACQD20X30S FAQ
The ACQD20X30S provides equal push and pull thrust of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum capacity of 24kgf at 1.0MPa. Because a rod occupies both chambers, the annular area is identical in each direction, making forces perfectly symmetric. The maximum standard stroke available for this 20mm bore is 100mm.
No, a plain ACQD does not hold position when air is lost; 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. The -S magnet works with reed or electronic switches for position sensing.
