Airtac ACQD Double Acting Compact Cylinder ACQD20X35S
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X35S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 35mm 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 ACQD20X35S
The AirTAC ACQD20X35S is a double-acting JIS compact cylinder with twin Ø10mm rods extending from both body ends. Because a rod occupies each chamber, the annular piston area is identical in both directions, yielding equal push and pull thrust of 117.8N at 0.5MPa and 164.9N at 0.7MPa. The symmetrical layout prevents rotation and doubles the guide length, allowing you to mount a small tool platform directly without adding an external anti-rotation guide.
This 20mm bore unit runs on 0.15-1.0MPa air supplied via M5x0.8 ports. It features fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The included -S piston magnet activates reed or solid-state electronic switches via the body grooves. The standard female M5x0.8 rod-end threads and 35mm stroke suit tight spaces, with a maximum standard stroke limit of 100mm for this bore.
Airtac ACQD Double Acting Compact Cylinder ACQD20X35S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X35S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 35 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 ACQD20X35S Is Used
Symmetrical Transfer Pusher
Drives a packaging line pusher where identical 117.8N extension and retraction forces at 0.5MPa ensure perfectly balanced part transfer cycles without momentum drift.
Twin-Guided Pick And Place
Handles small electronic components on a PCB assembly machine, using the second rod end to mount a sensor flag while the twin rods keep the gripper from twisting.
Dual-Station Diverter Actuation
Powers a low-profile conveyor sorting flap where the fixed TPU bumpers absorb repetitive taps and the compact 20mm body fits between adjacent conveyor rollers.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X35S the Right Cylinder?
When sizing this 20mm bore actuator, consider the adjacent bores: stepping down to 16mm yields 75.4N at 0.5MPa, while stepping up to 25mm provides 188.9N. Choose the ACQD20X35S when your application strictly requires equal bidirectional force and inherent rotational stability. If your mechanism only needs unidirectional thrust with higher forward power, a single-rod ACQ series cylinder might be a better fit. For heavy off-axis loads exceeding the twin rods' guide capacity, a linear-guided TACQ cylinder is recommended. Confirm your 35mm stroke, M5x0.8 porting, and female M5x0.8 rod threads when ordering.
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 ACQD20X35S FAQ
It delivers equal push and pull thrust of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum force of 24kgf at 1.0MPa. Push equals pull because the twin rods create identical annular areas on both sides. The operating pressure is 0.15-1.0MPa, and the maximum standard stroke for a 20mm bore is 100mm.
It uses fixed TPU elastomer bumpers at both ends to decelerate the piston, meaning there are no adjustable air cushions. The twin rods resist rotation and provide extended guiding without an external guide. Note that a plain ACQD does not hold its load if air pressure is lost; for fail-safe holding, you must add an external rod lock or pilot-operated check valve.
