Airtac ACQD Double Acting Compact Cylinder ACQD80X45
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X45 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 45mm 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 ACQD80X45
The AirTAC ACQD80X45 is a double-acting JIS compact cylinder featuring a twin-rod design where a piston rod protrudes from both ends of the riveted body. Because a rod occupies both internal chambers, the effective annular area is identical in each direction, yielding equal push and pull forces of 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. The dual rods inherently resist rotation and provide an extended guide length, allowing it to carry a tool platform directly without needing a separate external anti-rotation guide.
This 80mm bore unit integrates fixed NBR elastomer bumpers at both ends to decelerate the stroke, rather than relying on adjustable air cushions. It uses a PT3/8 port and a Ø25mm rod with a female M16x2.0 thread end. The body retains magnetic-switch grooves for positioning reed or solid-state sensors, though this specific configuration ships without a magnet. Note that a standard ACQD does not hold its load if air pressure is lost; a pilot-operated check valve or external rod lock is required for fail-safe holding.
Airtac ACQD Double Acting Compact Cylinder ACQD80X45 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X45 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 45 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 ACQD80X45 Is Used
Twin-Guided Pusher Station
Drives a wide packaging pusher plate in a carton erector, leveraging the dual rods to prevent yaw and maintain parallel alignment without a separate external guide rail.
Symmetric Transfer Mechanism
Powers a pick-and-place transfer arm in electronics assembly, utilizing the equal push/pull forces to execute identical extension and retraction cycles at consistent speeds.
Dual-Station Actuation
Actuates opposing clamp jaws simultaneously on a machining center, using the second protruding rod end to mount a sensor flag for confirming jaw position.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X45 the Right Cylinder?
Selecting this 80mm bore model provides 2267.8 N of equal bidirectional force at 0.5 MPa. If your application requires less thrust, the next size down is the 63mm bore delivering 1401.5 N, whereas stepping up to the 100mm bore yields 3524.8 N for heavier loads. If your mechanism only needs unidirectional push force and space is less critical, a single-rod ACQ cylinder might suffice. Conversely, if your payload demands exceptionally high lateral moment resistance beyond the twin rods, a guided TACQ cylinder offers a stiffer bearing solution. Confirm your 45mm stroke requirement and verify the female M16x2.0 rod end fits your mounting hardware.
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 ACQD80X45 FAQ
The ACQD80X45 delivers equal push and pull forces of 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum force of 463 kgf at 1.0 MPa. Push and pull forces are identical because the twin-rod design creates the same effective annular area in both directions. The operating pressure range is 0.15-1.0 MPa, and the maximum standard stroke available for this 80mm bore is 100mm.
This model uses fixed NBR elastomer bumpers at both ends to absorb impact energy, meaning there is no adjustable air cushion to tune. For high-speed or high-energy loads, you should add an external shock absorber or slow the approach speed. Additionally, a plain ACQD does not hold its load when air is lost or the valve is centered; the rod will drift. For fail-safe load holding, an external rod lock or pilot-operated check valve is required.
