Airtac ACQD Double Acting Compact Cylinder ACQD80X50S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X50S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 50mm 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 ACQD80X50S
The AirTAC ACQD80X50S is a double-acting JIS compact cylinder featuring a twin-rod design where a shaft exits both ends. Because a rod occupies each chamber, the annular areas match, yielding perfectly equal push and pull forces of 2267.8N at 0.5 MPa and 3175N at 0.7 MPa. This symmetry is ideal for applications requiring identical extension and retraction dynamics.
Twin Ø25mm rods resist torsion and provide an extended guide length, allowing you to mount a tool platform directly without needing a separate external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. Deceleration relies on fixed NBR elastomer bumpers at each end rather than adjustable air cushions. The -S option includes a piston magnet compatible with reed or solid-state switches installed in the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD80X50S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X50S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 50 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 ACQD80X50S Is Used
Twin-Guided Pusher
Drives a wide packaging pusher plate in a beverage line, using the dual rods to prevent plate yaw without an external guide rail.
Symmetric Transfer Unit
Powers a pick-and-place transfer bridge in electronics assembly, leveraging the equal push and pull forces for balanced vertical cycling.
Dual-Station Actuation
Indexes a machining fixture on a multi-spindle drill, using the second protruding rod end to trigger a solid-state sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X50S the Right Cylinder?
At 0.5 MPa this 80mm bore generates 2267.8N of force both directions. Stepping down to the 63mm bore yields 1401.5N, while moving up to the 100mm bore provides 3524.8N, giving you clear adjacent sizing options. If your mechanism only needs unidirectional thrust, a single-rod ACQ provides a shorter footprint. For heavy lateral loads, a guided TACQ might serve better. To order, confirm the 50mm stroke, PT3/8 port, and female M16x2.0 rod-end threads.
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 ACQD80X50S FAQ
It delivers equal push and pull forces of 2267.8N at 0.5 MPa and 3175N at 0.7 MPa, with a maximum holding capability of 463 kgf at 1.0 MPa. Push and pull match because the twin rods create identical annular areas on both sides. The maximum standard stroke available for an 80mm bore is 100mm.
No, a plain ACQ-type cylinder drifts when air is lost or a valve is centered. The fixed NBR bumpers only decelerate the rod near stroke ends and do not function as a brake. For fail-safe load holding, you must add an external rod lock or a pilot-operated check valve.
