Airtac ACQD Double Acting Compact Cylinder ACQD20X40B
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X40B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 40mm 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 ACQD20X40B
The AirTAC ACQD20X40B is a double-acting JIS compact cylinder featuring twin Ø10mm rods exiting both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa. The male M8x1.25 rod ends couple directly to your tooling, while the M5x0.8 ports supply air.
This symmetric design resists rotation and extends guide length, allowing a small platform to be carried without an external guide. The fixed TPU bumpers absorb end-of-stroke impacts across the 40mm travel, and the body retains magnetic-switch grooves for future automation upgrades. Note that this non-magnet variant ships without a piston magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD20X40B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X40B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 40 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 ACQD20X40B Is Used
Symmetric Transfer Arm
Drives a dual-ended pick-and-place arm where equal push and pull forces keep horizontal part transfers smooth and balanced.
Twin-Guided Pusher
Pushes product down a packaging lane without twisting, utilizing the anti-rotation stability of the dual rods over the 40mm stroke.
Dual-Station Actuation
Uses the second protruding rod end to trigger a mechanical flag or drive a secondary stop on a small electronics assembly fixture.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X40B the Right Cylinder?
Providing 117.8N of equal bidirectional force, this 20mm bore unit sits between the 16mm (75.4N) and 25mm (188.9N) sizes. Choose it when a single-rod ACQ lacks rotational stability or when a guided TACQ is physically too large. To configure correctly, specify the 40mm stroke, confirm the male M8x1.25 rod threads fit your load, and select PT porting.
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 ACQD20X40B FAQ
It delivers equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum capacity of 24kgf at 1.0MPa. The equal force is due to the double-rod design creating identical annular areas on both sides. The maximum standard stroke available for this 20mm bore is 100mm.
It uses fixed TPU elastomer bumpers at both ends to cushion impacts, meaning there is no adjustable air cushion. For high-speed applications, an external shock absorber is recommended. Also, a plain ACQD does not hold its load if air pressure is lost; you must add an external rod lock or pilot-operated check valve for fail-safe positioning.
