Airtac ACQD Double Acting Compact Cylinder ACQD80X80B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X80B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 80mm 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 ACQD80X80B
The AirTAC ACQD80X80B is an 80mm JIS compact pneumatic cylinder featuring a dual-rod design where a shaft protrudes from both ends. Because the piston sees identical annular areas in each direction, it generates identical push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa. The twin 25mm rods inherently resist rotation and extend the guiding length, allowing you to mount a tool platform directly without needing a separate external guide.
This double-acting unit utilizes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. It includes a male M22x1.5 rod-end thread for direct load coupling, a PT3/8 port, and integrated magnetic-switch grooves. Note that this specific configuration ships without a piston magnet and does not hold its position on air loss; a pilot-operated check valve or external rod lock is required for fail-safe load holding.
Airtac ACQD Double Acting Compact Cylinder ACQD80X80B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X80B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 80 mm |
| Acting type | Double acting, double rod |
| Port size | PT3/8 |
| Rod end thread | M16×2.0 female / M22×1.5 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 (Ø80mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 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 ACQD80X80B Is Used
Twin-Guided Tool Platform
Drives a machining fixture on a CNC lathe loader, using the dual rods to keep the tool centered and prevent rotational drift during heavy metalworking tasks.
Symmetric Transfer Unit
Indexes parts along an automotive assembly conveyor, utilizing the identical push and pull forces to maintain stable dual-station actuation across the line.
Dual-End Actuation
Operates a packaging diverter where one rod end moves the sorting flap while the opposite end directly mounts a sensor flag for position tracking.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X80B the Right Cylinder?
When sizing this 80mm bore option, the adjacent 63mm version yields 1401.5N at 0.5MPa, while the larger 100mm bore provides 3524.8N at the same pressure. If your application requires unilateral extension and higher forward thrust over reverse pull, the single-rod ACQ series is a better fit. For tasks demanding precise linear guidance without torsional deflection, this ACQD twin-rod configuration is optimal. Confirm your ordering essentials: an 80mm bore, 80mm stroke, male M22x1.5 rod thread, and PT3/8 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 ACQD80X80B FAQ
This 80mm double-acting cylinder provides equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum capacity of 463kgf at 1.0MPa. Push and pull forces are identical because the twin rods occupy both chambers, resulting in the same annular area in each direction. The maximum standard stroke available for this bore is 100mm.
Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions, so external shock absorbers may be needed for high-energy loads. Additionally, a plain ACQD does not hold its load when air pressure is lost or valves are centered; the rod will drift. For fail-safe holding, you must install an external rod lock or a pilot-operated check valve.
