Airtac ACQD Double Acting Compact Cylinder ACQD80X40B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X40B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 40mm 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 ACQD80X40B
The AirTAC ACQD80X40B is a double-acting JIS compact cylinder featuring a piston rod extending from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding perfectly equal push and pull forces of 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. This twin-rod architecture inherently resists rotation and provides a longer guide length, allowing you to carry a tool platform without needing a separate external anti-rotation guide.
This specific 80mm bore variant features a Ø25mm rod, PT3/8 ports, and a male M22x1.5 rod-end thread (-B) that couples directly to your load. It incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. While this unit ships without a magnet, the body retains magnetic-switch grooves for position sensing. Operating pressure spans 0.15-1.0 MPa, with a maximum standard stroke capacity of 100mm.
Airtac ACQD Double Acting Compact Cylinder ACQD80X40B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X40B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 40 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 ACQD80X40B Is Used
Twin-Guided Tooling Platform
Drives a machining fixture on a CNC lathe where the dual rods prevent rotational deflection under heavy 3175 N cutting loads.
Symmetric Transfer Pusher
Positions parts on a packaging line by using the equal push and pull forces to maintain precise centering during double-sided product transfers.
Dual-Station Actuation
Actuates a secondary mechanism on an automotive assembly press via the exposed second rod end while the primary side executes the main work stroke.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X40B the Right Cylinder?
When sizing this 80mm bore, note it delivers 2267.8 N of equal bidirectional force at 0.5 MPa. If your application requires less force, the 63mm bore provides 1401.5 N, whereas stepping up to the 100mm bore yields 3524.8 N. Choose this ACQD twin-rod model when your payload demands built-in anti-rotation support or requires driving a secondary load from the opposite rod end. If your mechanism already features an external guided rail and you only need unidirectional thrust, a single-rod ACQ cylinder might be a more compact fit. To order, confirm the 40mm stroke, the male M22x1.5 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 ACQD80X40B FAQ
The ACQD80X40B generates 2267.8 N of force at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum load capacity of 463 kgf at 1.0 MPa. Push and pull forces are exactly equal because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 80mm bore is 100mm.
No, a plain ACQD does not hold its load when air is lost or a valve is centered; the rod will drift. For fail-safe holding, you must install an external rod lock or pilot-operated check valve. For end-of-stroke deceleration, it uses fixed NBR elastomer bumpers rather than adjustable air cushions, so you should add an external shock absorber for high-speed or high-energy loads.
