Airtac ACQD Double Acting Compact Cylinder ACQD50X25
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X25 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm 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 ACQD50X25
The AirTAC ACQD50X25 is a double-acting JIS compact cylinder featuring a piston rod protruding from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This symmetry is ideal for applications requiring consistent bidirectional thrust without the force differential found in single-rod units.
Twin rods resist rotation and provide a longer guide length, allowing you to carry a small tool platform without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. This 50mm bore variant uses a PT1/4 port, a Ø20mm rod with an M10x1.5 female thread, and relies on fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. Note that this specific configuration ships without a magnet, though the body retains sensor grooves for adding reed or solid-state switches if needed later.
Airtac ACQD Double Acting Compact Cylinder ACQD50X25 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X25 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 25 mm |
| Acting type | Double acting, double rod |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø50mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 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 ACQD50X25 Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place arm in electronics assembly, using the matching push and pull forces to move components smoothly between stations.
Twin-Guided Pusher
Pushes cartons on a packaging line without twisting, leveraging the inherent anti-rotation properties of the dual rods to keep the contact plate square.
Dual-Station Actuation
Actuates a second mechanism via the opposite rod end on a textile machine, synchronizing two processes with a single compact actuator.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X25 the Right Cylinder?
For sizing context, scaling down to a 40mm bore yields 527.8N at 0.5MPa, while stepping up to a 63mm bore provides 1401.5N at 0.5MPa. If your application only needs unidirectional thrust and you want a higher forward force, a single-rod ACQ cylinder might be a better choice. If your load demands precise lateral stability over a longer span, a guided TACQ cylinder could be more appropriate. When ordering this ACQD50X25, confirm your 25mm stroke requirement, the default female M10x1.5 rod-end thread, and the PT1/4 port size.
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 ACQD50X25 FAQ
It delivers an equal push and pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum holding capacity of 168kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 50mm bore is 100mm.
No, a plain ACQD does not hold position when air is lost, as the fixed NBR bumper only decelerates the rod near the stroke end. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
