Airtac ACQD Double Acting Compact Cylinder ACQD80X40S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X40S 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 ACQD80X40S
The AirTAC ACQD80X40S is a double-acting JIS compact cylinder featuring twin rods that exit from both ends of the body. Because a rod occupies each chamber, the effective annular area remains identical in both directions, yielding equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa. This symmetry is ideal for applications requiring consistent bi-directional thrust up to a maximum 463kgf at 1.0MPa.
The dual-rod architecture inherently resists rotation and provides an extended guide length, allowing you to carry a tool platform directly without needing a separate external guide. The 80mm bore uses a PT3/8 port and a 25mm piston rod with an M16x2.0 female thread. Deceleration is handled by fixed NBR elastomer bumpers at both ends, while the integrated -S magnet supports reed or solid-state switches via the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD80X40S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X40S |
|---|---|
| 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 ACQD80X40S Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer carriage on packaging machinery where matching push and pull thrust prevents load skewing during rapid reversals.
Twin-Guided Stamping Platform
Mounts a small stamping head directly to the cylinder body in CNC auxiliary lines, utilizing the extended guide length to resist lateral deflection.
Dual-Station Actuation
Uses the second protruding rod end to trigger a solid-state sensor flag on an assembly machine while the primary end moves the workpiece.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X40S the Right Cylinder?
Selecting this 80mm bore involves comparing neighbouring sizes: the 63mm bore provides 1401.5N at 0.5MPa, whereas the 100mm bore offers 3524.8N at 0.5MPa. If your mechanism only requires heavy thrust in one direction, a single-rod ACQ cylinder might suffice, but choose this ACQD model when symmetric force and high torsional rigidity are mandatory. Remember that a plain compact cylinder drifts when air pressure is lost; for fail-safe load holding, you must integrate an external rod lock or pilot check valve. Confirm your ordering essentials: 40mm stroke, -S magnet, and standard 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 ACQD80X40S FAQ
This double-acting cylinder generates 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 equal because the twin rods create the same annular area in both chambers. The maximum standard stroke available for this 80mm bore is 100mm.
The twin-rod design resists rotation and provides a longer guide length without needing an external guide. End-of-stroke deceleration is managed by fixed NBR elastomer bumpers, which are not adjustable; for high-energy impacts, use an external shock absorber. The -S magnet allows mounting reed or electronic switches directly into the body grooves.
