Airtac ACQD Double Acting Compact Cylinder ACQD80X35SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X35SB 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 ACQD80X35SB
The AirTAC ACQD80X35SB is a double-acting JIS compact cylinder featuring twin rods that exit both ends of the riveted body. Because a rod occupies each chamber, the annular area is identical on extension and retraction, yielding equal push and pull force of 2267.8N at 0.5MPa (3175N at 0.7MPa). This symmetry is ideal for applications requiring perfectly balanced bi-directional thrust.
The dual rods provide extended guide length and high torsional resistance, allowing you to mount a tool platform directly without needing an external anti-rotation guide. This SB variant includes a male M22x1.5 rod-end thread for direct load coupling and a built-in piston magnet for position sensing. Deceleration is handled by fixed NBR elastomer bumpers at each end, ensuring reliable operation within the 30-500mm/s speed range.
Airtac ACQD Double Acting Compact Cylinder ACQD80X35SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X35SB |
|---|---|
| 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 ACQD80X35SB Is Used
Twin-Guided Pusher
Drives a heavy machining fixture back and forth on a production line, using the dual rods to prevent platform deflection under offset loads.
Symmetric Transfer Unit
Shifts large automotive subassemblies between processing stations, leveraging the equal push and pull forces to maintain smooth, balanced cycling.
Dual-Station Actuation
Operates two clamps simultaneously in a packaging machine, using the second protruding rod end to drive a secondary mechanism or sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X35SB the Right Cylinder?
Delivering 2267.8N both ways, this 80mm bore sits between the 63mm unit (1401.5N) and the 100mm unit (3524.8N) at 0.5MPa. If your mechanism only needs thrust in one direction, a single-rod ACQ offers a lighter footprint, while a guided TACQ is preferable if your load exceeds the torsional limits of the twin rods. To order, confirm the 35mm stroke, PT3/8 port size, and the SB options (magnet and male M22x1.5 rod thread).
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 ACQD80X35SB FAQ
It 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. Because the double-rod design creates equal annular areas on both sides, thrust is identical in both directions. The maximum standard stroke available for this 80mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both stroke ends for impact absorption; these are not adjustable air cushions, so external shock absorbers may be needed for high-energy loads. Additionally, a plain ACQD does not hold position when air pressure is lost or valves are centered—an external rod lock or pilot-operated check valve is required for fail-safe load holding.
