Airtac ACQD Double Acting Compact Cylinder ACQD25X70S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X70S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 70mm 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 ACQD25X70S
The AirTAC ACQD25X70S is a double-acting JIS compact cylinder featuring a 25mm bore and 70mm stroke. A Ø12mm piston rod protrudes from both ends, creating identical annular working areas. This design yields perfectly equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa, enabling symmetrically balanced motion cycles without differential pressure biases.
Twin rods provide an extended guide length and inherent anti-rotation properties, eliminating the need for a separate external guide in many applications. The second rod end can drive a sensor flag or a secondary load. Fixed TPU elastomer bumpers absorb impact at stroke ends, while the built-in magnet (-S) interfaces with reed or solid-state switches via the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD25X70S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X70S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 70 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø25mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 189 N | 189 N |
| 0.7 MPa | 264 N | 264 N |
| Max (@1.0 MPa) | 39 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 ACQD25X70S Is Used
Symmetric Transfer Arms
Drives a dual-ended pick-and-place arm where equal push and pull forces maintain balanced dynamics while moving components between machining centers.
Twin-Guided Pusher
Acts as a part pusher on a conveyor line, using the inherent anti-rotation property of the dual rods to keep the tooling plate perfectly aligned.
Dual-Station Actuation
Powers a small testing fixture where one rod end strokes the primary test piece and the opposite end mounts a sensor flag for position verification.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X70S the Right Cylinder?
This 25mm bore generates 188.9N of force both directions at 0.5MPa. For lighter duties, the 20mm bore provides 117.8N, while the 32mm bore offers 301.6N for heavier demands. If your mechanism strictly requires non-rotating guidance without equal force, a single-rod ACQ paired with an external slide rail might fit better. When ordering, confirm the 70mm stroke, M5x0.8 port, and the default M6x1.0 female 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 ACQD25X70S FAQ
The cylinder delivers equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa, with a maximum capacity of 39kgf at 1.0MPa. Forces are identical both ways because the twin rods occupy both chambers, creating matching annular areas. The maximum standard stroke for this 25mm bore is 100mm.
The twin rods resist rotation and extend guide length. The -S magnet works with reed or electronic switches in the body grooves. Fixed TPU bumpers decelerate the piston near stroke ends but do not hold the load on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve.
