Airtac ACQD Double Acting Compact Cylinder ACQD80X35S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X35S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 35mm 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 ACQD80X35S
The AirTAC ACQD80X35S is a double-acting JIS compact cylinder where a Ø25mm piston rod protrudes from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding perfectly 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 without force imbalance.
The twin-rod architecture inherently resists rotation and provides an extended guide length, allowing you to carry a tooling platform directly without adding an external non-rotating guide. The second rod end can drive a sensor flag or a secondary load. It features a fixed NBR elastomer bumper at each end for end-of-stroke deceleration, and the included -S piston magnet works with reed or solid-state switches via the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD80X35S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X35S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 35 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 ACQD80X35S Is Used
Symmetric Transfer Pusher
Drives a packaging line shuttle from both ends, ensuring equal 3175N push and pull thrust at 0.7MPa for stable bi-directional product transfer without rotational drift.
Dual-Station Actuator
Uses the secondary rod end to trigger a remote solid-state sensor flag on a CNC machining center while the primary end positions a 35mm stroke clamping jaw.
Twin-Guided Lifter
Lifts a heavy electronics assembly fixture in a vertical press, leveraging the extended guide length of the dual rods to prevent binding without external guide rails.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X35S the Right Cylinder?
Delivering 2267.8N of equal force both ways at 0.5MPa, this 80mm bore fits between the 63mm (1401.5N) and 100mm (3524.8N) models. Choose the ACQD80X35S when your fixture demands high symmetric thrust and built-in anti-rotation within a 35mm stroke. If your mechanism only needs force in one direction, a single-rod ACQ80 is more compact. For heavy lateral loads exceeding the twin rods' guide capacity, consider a guided TACQ cylinder. This unit has a PT3/8 port and a female M16x2.0 rod-end thread; confirm your mounting and thread requirements when ordering.
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 ACQD80X35S FAQ
The ACQD80X35S provides equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum rated force of 463kgf at 1.0MPa. Push and pull forces are equal because the double-rod design creates the same annular area in both chambers. The standard stroke maximum for this 80mm bore is 100mm, the port is PT3/8, and the default rod-end thread is female M16x2.0.
No, a standard ACQD does not hold position on air loss; the rod will drift and an external rod lock or pilot-operated check valve is required for fail-safe holding. For end-of-stroke deceleration, it uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. For high kinetic energy loads, you should add an external shock absorber or slow the approach speed.
