Airtac ACQD Double Acting Compact Cylinder ACQD20X20B
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X20B 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 ACQD20X20B
The AirTAC ACQD20X20B 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. This symmetry is ideal for applications requiring consistent bi-directional thrust. The male M8x1.25 rod-end threads couple directly to tooling, while the body uses a fixed TPU elastomer bumper at each end for end-of-stroke deceleration.
This 20mm bore unit resists rotation without needing an external anti-rotation guide, saving space and simplifying machine design. The secondary rod end can drive a sensor flag or a second load. Operating pressure spans 0.15-1.0MPa, and the body retains magnetic-switch grooves, though this specific SKU ships without a piston magnet. Note that a plain ACQD does not hold position upon air loss; a fail-safe hold requires an external rod lock or pilot check valve.
Airtac ACQD Double Acting Compact Cylinder ACQD20X20B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X20B |
|---|---|
| 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 ACQD20X20B Is Used
Symmetric Transfer Pusher
Drives a dual-sided pusher in packaging lines where equal 117.8N force in both directions prevents part crushing during extension and retraction.
Twin-Guided Pick & Place
Carries a small gripper platform on a CNC loader; the twin rods resist torsional loads without adding a separate external guide rail.
Dual-Station Actuation
Simultaneously triggers two micro-switches on an assembly fixture using the second protruding rod end as a remote sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X20B the Right Cylinder?
With 117.8N force at 0.5MPa, sizing this 20mm bore against neighbors is straightforward: step down to a 16mm bore for 75.4N, or up to a 25mm bore for 188.9N if higher thrust is required. Choose the ACQD20X20B when symmetric push/pull cycles and anti-rotation are mandatory. If your mechanism already has an external linear guide and only needs forward thrust, a single-rod ACQ cylinder is more compact. Confirm the 20mm stroke, the M5x0.8 port, and the male M8x1.25 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 ACQD20X20B FAQ
It delivers an equal push and pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum holding force of 24kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates equal annular areas on both sides of the piston. The maximum standard stroke for this 20mm bore is 100mm, and operating pressure is 0.15-1.0MPa.
The twin rods resist rotation and provide a longer guide length, eliminating the need for an external anti-rotation guide in many setups. End cushioning is provided by fixed TPU elastomer bumpers, not adjustable air cushions. While the body features magnetic-switch grooves, this specific model ships without a piston magnet; add an -S option if reed or solid-state switch sensing is required.
