Airtac ACQD Double Acting Compact Cylinder ACQD20X75B
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X75B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 75mm 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 ACQD20X75B
The AirTAC ACQD20X75B is a double-acting JIS compact cylinder where a Ø10 mm piston rod protrudes from both ends. Because the twin rods occupy both internal chambers, the effective annular area is identical in each direction. This means push and pull forces are perfectly equal at 117.8 N (0.5 MPa) and 164.9 N (0.7 MPa), enabling symmetric cycles without force imbalance.
The dual rods also provide a longer guide length and inherent anti-rotation properties, allowing you to mount a small tool platform directly without needing a separate external guide. This 20 mm bore unit features fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration. It includes the -B male rod-end thread (M8x1.25) for direct load coupling, and the body retains magnetic-switch grooves for future sensing upgrades.
Airtac ACQD Double Acting Compact Cylinder ACQD20X75B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X75B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 75 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 ACQD20X75B Is Used
Symmetric Transfer Pusher
Drives a dual-sided pick-and-place head in electronics assembly, using the equal push and pull forces to maintain consistent positioning during component transfer.
Twin-Guided Stripper Plate
Actuates a small stripper plate in a stamping die, relying on the twin rods to resist rotation and prevent binding during the 75 mm ejection stroke.
Dual-Station Actuation
Powers a secondary load or sensor flag from the opposite rod end on a packaging machine, synchronizing two operations from one compact body.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X75B the Right Cylinder?
When sizing this 20 mm bore, stepping down to a 16 mm bore yields 75.4 N of equal force, while stepping up to a 25 mm bore provides 188.9 N at 0.5 MPa. If your application only needs unidirectional thrust and has external rail support, a single-rod ACQ cylinder might offer a lighter footprint. For applications demanding high lateral load capacity and precise non-rotating guidance over longer strokes, a guided TACQ cylinder is the better choice. To order, confirm the 75 mm stroke, the M8x1.25 male rod thread, and the M5x0.8 PT port.
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 ACQD20X75B FAQ
This double-acting cylinder provides equal push and pull forces of 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a maximum force of 24 kgf at 1.0 MPa. Push and pull are equal because the twin rods create identical annular areas on both sides. The stroke is 75 mm, and the maximum standard stroke for this 20 mm bore is 100 mm.
No, a standard ACQD does not hold position upon air loss; the rod will drift and the fixed TPU bumper only decelerates near the stroke end. For fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
