Airtac ACQD Double Acting Compact Cylinder ACQD80X5SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X5SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 5mm 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 ACQD80X5SB
The AirTAC ACQD80X5SB is a double-acting JIS compact cylinder featuring a piston rod exiting both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 2267.8N at 0.5MPa. This symmetric thrust is ideal for applications requiring consistent bi-directional power. The twin rods inherently resist rotation and significantly increase guide length, allowing the unit to carry a tool platform without needing a separate external guide.
This 80mm bore model includes an integrated piston magnet (-S) for tracking with reed or solid-state electronic switches, and a male M22x1.5 thread (-B) on both rod ends for direct load coupling. It uses PT3/8 ports and relies on fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. Operating pressure spans 0.15-1.0MPa, and the unit handles speeds of 30-500mm/s. Note that a plain ACQD does not hold its position upon air loss; maintaining a load requires an external pilot check valve or rod lock.
Airtac ACQD Double Acting Compact Cylinder ACQD80X5SB Technical Specifications

| 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 ACQD80X5SB Is Used
Twin-Guided Press Tool
Drives a heavy stamping die in an automotive parts plant, utilizing the dual rods to maintain parallelism and prevent binding under high offset loads.
Symmetric Transfer Clamp
Actuates a centering clamp on a machining center, using the equal push and pull forces to securely grip and release workpieces without directional force variance.
Dual-Station Actuation
Powers a short 5mm ejection stroke on an automated assembly line, using the second rod end to mount a sensor flag for confirming part ejection.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X5SB the Right Cylinder?
When sizing this 80mm bore, stepping down to the 63mm version yields 1401.5N at 0.5MPa, while stepping up to the 100mm provides 3524.8N. If your mechanism only needs thrust in one direction and lacks space for twin rods, a single-rod ACQ cylinder is more appropriate. For applications needing precise non-rotating guidance over a long span, a guided TACQ cylinder might be a better structural fit. To order the ACQD80X5SB, confirm the 5mm stroke, the male M22x1.5 rod-end threads, the required -S magnet for sensing, and the PT3/8 port size.
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 ACQD80X5SB FAQ
The ACQD80X5SB delivers equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum holding capacity of 463kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates equal annular areas on both sides. The standard maximum stroke for this 80mm bore is 100mm, and this specific unit has a 5mm stroke. It features a 25mm rod, PT3/8 ports, and male M22x1.5 rod-end threads.
The twin rods exiting both ends resist rotation and provide a longer guide length without needing an external guide. It uses fixed NBR elastomer bumpers at both ends for deceleration, meaning there are no adjustable air cushions; for high-speed or high-energy loads, an external shock absorber is required. Additionally, a plain ACQD cylinder will drift if air pressure is lost, so an external rod lock or pilot-operated check valve is necessary for fail-safe load holding.
