Airtac ACQD Double Acting Compact Cylinder ACQD20X20BH
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X20BH is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm 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 ACQD20X20BH
The AirTAC ACQD20X20BH is a double-acting JIS compact cylinder featuring a 10mm piston rod exiting both ends. Because a rod occupies each chamber, the annular area remains identical in both directions, generating an equal push and pull force of 117.8N at 0.5MPa. This symmetric thrust is ideal for balanced cycling tasks.
Twin rods provide extended guide length and inherent anti-rotation properties without needing an external guide. This specific unit includes M8x1.25 male rod ends for direct mounting and fixed TPU bumpers to absorb end-of-stroke impact. Although it lacks a magnet, the body retains sensor grooves for external reed or solid-state switches.
Airtac ACQD Double Acting Compact Cylinder ACQD20X20BH Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 20 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 ACQD20X20BH Is Used
Symmetric Transfer Pusher
Drives a dual-sided pick-and-place head in electronics assembly, using the equal thrust to push and retract components without shifting the center of mass.
Twin-Guided Strip Ejector
Ejects machined parts from a CNC fixture using both rod ends to maintain parallelism and prevent the tooling plate from twisting under offset loads.
Dual-Station Actuation
Powers a small clamping mechanism in a semiconductor bonding machine, using the second rod end to trigger a solid-state sensor flag at the opposite stroke limit.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X20BH the Right Cylinder?
Delivering 117.8N of thrust both ways at 0.5MPa, this 20mm bore sits neatly between the 16mm (75.4N) and 25mm (188.9N) sizes. Choose the ACQD20X20BH when your application requires precise anti-rotation guidance within a compact 20mm stroke envelope. If your mechanism only needs thrust from one side and lacks torsional stress, a single-rod ACQ series may suffice. For heavier lateral loads requiring independent external guidance, a guided TACQ cylinder is preferable. Confirm your porting (M5x0.8) and the M8x1.25 male rod thread 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 ACQD20X20BH FAQ
The push and pull forces are equal at 117.8N @0.5MPa and 164.9N @0.7MPa, with a maximum of 24kgf @1.0MPa. This equality occurs because the double-rod design creates the same annular area in both chambers. The maximum standard stroke for this 20mm bore is 100mm.
The twin rods resist rotation and add guide length. It uses fixed TPU elastomer bumpers at both ends rather than adjustable air cushions. Note that a plain ACQ-type cylinder 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 holding.
