Airtac ACQD Double Acting Compact Cylinder ACQD80X90SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X90SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 90mm 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 ACQD80X90SB
The AirTAC ACQD80X90SB is an 80mm JIS compact double-rod cylinder featuring a 90mm stroke, a built-in magnet (-S), and male rod-end threads (-B). A Ø25mm piston rod extends from both front and rear covers, creating an identical annular working area in each chamber. This architecture yields perfectly equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa, enabling perfectly symmetric cycles without force imbalances.
Twin rods inherently resist rotational torque and provide an extended guide length, allowing you to mount a tool platform directly without needing an external anti-rotation guide. The protruding M22x1.5 male threads couple directly to your load, while the opposite rod end can drive a sensor flag or secondary mechanism. NBR elastomer bumpers fixed inside the body decelerate impacts at stroke extremes, and the integrated magnet supports both reed and solid-state electronic switches along the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD80X90SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X90SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 90 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 ACQD80X90SB Is Used
Twin-Guided Tool Platform
Drives a machining fixture on a CNC lathe, using the dual rods to maintain strict parallelism and absorb cutting torque without an external guide rail.
Symmetric Transfer Unit
Executes a balanced pick-and-place transfer between two packaging lanes, leveraging the identical 3175N push and pull forces to maintain stable acceleration in both travel directions.
Dual-Station Actuation
Indexes two separate stamping stations simultaneously from a central body, using the rear rod extension to trigger a positional limit switch via the integrated magnet.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X90SB the Right Cylinder?
For 0.5MPa operations, this 80mm bore delivers 2267.8N of equal bidirectional force. If your payload requires less thrust, the adjacent 63mm bore provides 1401.5N; if you need more power, stepping up to the 100mm bore yields 3524.8N. Choose a single-rod ACQ when equal push/pull forces are not required and space is limited, or select a TACQ slide unit when carrying extreme lateral loads. To order this version correctly, confirm the 90mm stroke, the -S magnet option, and the -B male M22x1.5 rod-end specification.
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 ACQD80X90SB FAQ
The 80mm bore generates an equal push and pull force 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 identical because the twin rods occupy both chambers, creating the same effective annular area in each direction. The 90mm stroke is well within the 100mm maximum standard stroke limit for this bore size.
It relies on fixed NBR elastomer bumpers at both stroke ends to absorb impact energy; it does not feature adjustable air cushions. For high-speed or high-mass applications, you should add an external shock absorber. Additionally, a plain ACQD does not hold its load if air pressure drops—the rod will drift—so an external rod lock or pilot-operated check valve is required for fail-safe positioning.
