Airtac ACQD Double Acting Compact Cylinder ACQD80X20B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X20B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 20mm 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 ACQD80X20B
The AirTAC ACQD80X20B is a double-acting JIS compact cylinder featuring twin rods extending from both body ends. Because a piston rod occupies each chamber, the effective annular area is identical in either direction. This design yields equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa, ensuring perfectly symmetric cycles without force imbalance.
Twin rods drastically resist rotation and extend the guide length, letting you mount a tool platform directly without needing an external anti-rotation guide. This 80mm bore unit uses a Ø25mm rod, PT3/8 port, and a male M22x1.5 rod-end thread for direct load coupling. It relies on fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions. Note that without external pneumatics, a standard unit will not hold its position if air pressure drops.
Airtac ACQD Double Acting Compact Cylinder ACQD80X20B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X20B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 20 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 ACQD80X20B Is Used
Twin-Guided Pusher
Drives a wide web-guiding pusher in a paper converting machine, using the dual rods to prevent yaw and maintain parallel contact across the rollers.
Symmetric Transfer
Actuates a dual-sided parts transfer arm in automotive assembly, utilizing the equal push and pull forces to move heavy chassis brackets smoothly in both directions.
Dual-Station Actuation
Powers a secondary stamping station in packaging equipment, using the opposite rod end to trigger a mechanical flag for a synchronized downstream cut.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X20B the Right Cylinder?
Selecting this 80mm bore with a 20mm stroke provides 2267.8N of force at 0.5MPa. If your application requires slightly less thrust, stepping down to a 63mm bore yields 1401.5N at 0.5MPa. Conversely, moving up to a 100mm bore offers 3524.8N at 0.5MPa. This specific configuration includes the -B male thread option (M22x1.5) for direct mounting, but ships without the -S magnet. If your mechanism only needs unidirectional thrust, a single-rod ACQ might be more space-efficient. For pure vertical lifting without drift, pair this cylinder with an external pilot-operated check valve.
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 ACQD80X20B FAQ
This double-rod cylinder 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. Forces are identical in both directions because the rod occupies both chambers. The maximum standard stroke available for this 80mm bore is 100mm.
The twin rods exiting both ends resist rotation and provide a longer guide length, eliminating the need for a separate external guide. End-of-stroke deceleration is handled by fixed NBR elastomer bumpers, not adjustable air cushions. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach speed.
