Airtac ACQD Double Acting Compact Cylinder ACQD20X30B
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X30B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 30mm 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 ACQD20X30B
The AirTAC ACQD20X30B is a double-acting JIS compact cylinder featuring twin rods extending from both ends. Because a rod occupies each chamber, the annular area is identical on both sides, yielding equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa. This symmetry is ideal for applications requiring consistent force in both directions.
The dual-rod design inherently resists rotation and provides a longer guide length, allowing the unit to support a small tool platform without needing an external anti-rotation guide. It features a fixed TPU elastomer bumper at each end for end-of-stroke deceleration, M5x0.8 ports, and an M8x1.25 male thread on both rod ends for direct load coupling. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD20X30B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X30B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 30 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 ACQD20X30B Is Used
Symmetric Transfer Mechanism
Drives a pick-and-place head in electronics assembly, utilizing the equal push and pull forces to move components smoothly in both directions without force imbalance.
Twin-Guided Pusher
Pushes product along a conveyor in packaging machinery, where the dual-rod construction prevents jaw rotation and maintains precise alignment without an external guide rail.
Dual-Station Actuation
Actuates a secondary cam or sensor flag from the rear rod end on a CNC lathe loader, while the front rod end drives the main clamping action simultaneously.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X30B the Right Cylinder?
When sizing this 20mm bore actuator, consider the neighboring options: the 16mm bore provides 75.4N at 0.5MPa, while the 25mm bore offers 188.9N at 0.5MPa. Choose the ACQD20X30B when your application demands approximately 118N of symmetrical force and 30mm of travel. If your mechanism only requires force in one direction and space is highly restricted, a single-rod ACQ cylinder might suffice. For loads needing precise non-rotational guidance over a longer span, a guided TACQ cylinder is recommended. To order, confirm the 20mm bore, 30mm stroke, and the B option for M8x1.25 male rod threads.
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 ACQD20X30B FAQ
The ACQD20X30B operates at 0.15-1.0MPa and delivers an equal push and pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum force of 24kgf at 1.0MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The maximum standard stroke available for the 20mm bore is 100mm.
This model uses fixed TPU elastomer bumpers at both ends to decelerate the piston, meaning there is no adjustable air cushion. For high-speed or high-energy loads, an external shock absorber or slower approach speed is required. Additionally, a plain ACQD does not hold position if air pressure is lost; a fail-safe hold requires an external rod lock or pilot-operated check valve.
