Airtac ACQD Double Acting Compact Cylinder ACQD20X50B
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X50B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 50mm 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 ACQD20X50B
The AirTAC ACQD20X50B 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 on extension and retraction, yielding perfectly equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa. This symmetric thrust is ideal for balanced cycles, while the dual rods provide extended guide length and inherent anti-rotation properties.
This specific configuration includes male M8x1.25 rod-end threads for direct load coupling and M5x0.8 pneumatic ports. The compact riveted body incorporates fixed TPU elastomer bumpers at both ends to decelerate impact rather than relying on adjustable air cushions. Although it lacks a built-in magnet, the body retains sensor grooves for external mounting.
Airtac ACQD Double Acting Compact Cylinder ACQD20X50B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X50B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 50 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 ACQD20X50B Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place beam in electronics assembly, using the equal push and pull forces to maintain consistent timing in both directions.
Twin-Guided Pusher
Indexes a small tooling platform on a packaging machine without twisting, leveraging the dual rods for extended guide length and rotational resistance.
Dual-Station Actuation
Actuates a secondary mechanism via the second rod end on a test fixture while the primary side drives the main workpiece, saving space.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X50B the Right Cylinder?
Providing 117.8N of symmetric force at 0.5MPa, this 20mm bore sits between the 16mm variant (75.4N) and the 25mm variant (188.9N). Choose this model when your application requires equal push/pull thrust and rotational stability without adding an external guide. If asymmetric extension force is acceptable and space is tight, a single-rod ACQ20 cylinder may suffice. For precise load holding on air loss, pair this cylinder with an external pilot-operated check valve or rod lock, as the fixed bumper only decelerates near stroke end. Confirm your ordering code includes the B suffix for the male M8x1.25 thread.
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 ACQD20X50B FAQ
It delivers equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum thrust of 24kgf at 1.0MPa. Push and pull are identical because the twin rods create equal annular areas on both sides. The max standard stroke for a 20mm bore is 100mm. This unit features an M8x1.25 male rod thread and M5x0.8 ports.
It uses fixed TPU elastomer bumpers at both ends to absorb impact energy, not adjustable air cushions. For high-energy cycles, add an external shock absorber. A plain ACQD does not hold position when air is lost; the rod drifts and the bumper only decelerates near stroke end. Use an external rod lock or pilot check valve for fail-safe load holding.
