Airtac ACQD Double Acting Compact Cylinder ACQD80X25B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X25B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 25mm 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 ACQD80X25B
The AirTAC ACQD80X25B is a double-acting JIS compact cylinder where a rod protrudes from both ends. Because the rod occupies both chambers, the annular area is identical in each direction, yielding equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa. This model includes a male M22x1.5 rod-end thread (-B) for direct load coupling and uses a PT3/8 port.
Twin rods provide a longer guide length and inherently resist rotation, allowing you to carry a tool platform without adding a separate external guide. The fixed NBR elastomer bumpers at both ends decelerate the motion near stroke ends, though external shock absorbers are recommended for high-energy cycles. Note that this specific unit ships without a magnet, meaning the integrated sensor grooves are present but inactive for reed or solid-state switches.
Airtac ACQD Double Acting Compact Cylinder ACQD80X25B Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 25 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 ACQD80X25B Is Used
Twin-Guided Pusher
Drives a wide format pusher plate in packaging machinery, using the dual rods to prevent yaw and maintain precise alignment without a separate external guide rail.
Symmetric Transfer Unit
Executes equal push and pull cycles on a horizontal transfer line, leveraging the identical annular area to ensure consistent force during both the advance and retract strokes.
Dual-Station Actuation
Actuates a secondary mechanism or sensor flag from the rear rod end on an automated assembly machine while the primary rod drives the main workpiece.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X25B the Right Cylinder?
Selecting this 80mm bore with a 25mm stroke provides a maximum holding force of 463kgf at 1.0MPa. If your application requires less force, stepping down to a 63mm bore yields 1401.5N at 0.5MPa, while moving up to a 100mm bore provides 3524.8N at 0.5MPa. A single-rod ACQ cylinder is preferable if you only need unidirectional thrust and want to save space. If your process demands fail-safe load holding during air loss, pair this cylinder with an external rod lock or pilot-operated check valve, as the fixed bumper only decelerates near the stroke end and cannot lock the piston. When ordering, confirm the 25mm stroke, the male M22x1.5 rod thread, and the PT3/8 porting.
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 ACQD80X25B FAQ
It delivers an equal push and pull force of 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum holding capacity of 463kgf at 1.0MPa. The push and pull forces are identical because the rod occupies both chambers, creating the same annular area in each direction. The standard stroke limit for this 80mm bore is 100mm.
The twin rods resist rotation and extend the guide length. This specific model lacks a magnet, so the body grooves cannot interface with reed or solid-state switches. Fixed NBR bumpers decelerate the piston near the ends, but the cylinder will not hold its load if air is lost; an external rod lock or pilot check valve is required for fail-safe holding.
