Airtac ACQD Double Acting Compact Cylinder ACQD25X90S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X90S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 90mm 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 ACQD25X90S
The AirTAC ACQD25X90S is a double-acting JIS compact cylinder featuring twin Ø12mm rods that exit both ends of the riveted body. Because a piston rod occupies both internal chambers, the effective annular area remains identical in each direction. This yields perfectly equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa, ensuring symmetric cycle dynamics without the force differential found in single-rod variants.
The dual rods inherently resist rotation and provide an extended guide length, allowing you to mount a small tool platform directly without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. Deceleration relies on fixed TPU elastomer bumpers at both ends, while the integrated -S piston magnet interfaces cleanly with reed or solid-state electronic switches via the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD25X90S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X90S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 90 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 ACQD25X90S Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place manipulator in electronics assembly, leveraging equal 264.5N force for perfectly balanced part transfer.
Twin-Guided Pusher
Pushes PCB panels through a fluxing station on a conveyor, using the twin rods to prevent chassis twist without an external guide rail.
Dual-Station Actuation
Actuates a secondary stamping head via the rear rod end on a packaging line, while the front rod drives a primary sealing jaw.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X90S the Right Cylinder?
For sizing context, stepping down to a bore 20 yields 117.8N at 0.5MPa, while stepping up to a bore 32 provides 301.6N at 0.5MPa. If your application strictly requires unequal push-over-pull mechanics, a single-rod ACQ fits better. For heavier lateral loads requiring a longer bearing, a guided TACQ series is recommended. When ordering, confirm the 90mm stroke (within the 100mm max standard), the M5x0.8 port, and the default female M6x1.0 rod-end thread.
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 ACQD25X90S FAQ
The push and pull forces are equal at 188.9N @0.5MPa and 264.5N @0.7MPa, with a maximum capacity of 39kgf @1.0MPa. The 90mm stroke is standard for this 25mm bore (max 100mm). Operating pressure is 0.15-1.0MPa. Push equals pull because the twin rods create identical annular piston areas in both directions.
Fixed TPU elastomer bumpers absorb impact at both stroke ends; they are not adjustable air cushions. The dual rods resist rotation and double the guide length, allowing direct tool mounting. A plain ACQD does not hold position on air loss, so an external rod lock or pilot check valve is required for fail-safe load holding.
