Airtac ACQD Double Acting Compact Cylinder ACQD50X250B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X250B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 250mm 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 ACQD50X250B
The AirTAC ACQD50X250B is a double-acting JIS compact cylinder where a rod protrudes from both ends. Because the twin rods occupy both chambers, the effective annular area remains identical in each direction. This means push and pull forces are perfectly equal at 824.6N at 0.5MPa and 1154.5N at 0.7MPa, enabling perfectly symmetric cycle dynamics without differential pressure biases.
Featuring a 50mm bore and a 250mm stroke, this long-stroke made-to-order variant exceeds the standard 100mm maximum. The twin rods prevent rotation and extend the guide length, allowing you to mount a tooling platform directly without needing an external guide. The male M18x1.5 rod-end threads couple directly to your load, while fixed NBR elastomer bumpers absorb impact energy at stroke ends rather than relying on adjustable cushions.
Airtac ACQD Double Acting Compact Cylinder ACQD50X250B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X250B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 250 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 ACQD50X250B Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place beam in packaging lines where equal 1154.5N push and pull forces prevent asymmetric drift during high-speed product transfers.
Twin-Guided Pusher
Pushes heavy pallets on a conveyor using the extended guide length of the dual rods to resist twisting moments without needing an external linear guide carriage.
Dual-Station Actuation
Actuates a secondary mechanism or sensor flag from the rear rod end on an automated assembly machine while the front rod drives the primary workpiece.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X250B the Right Cylinder?
When sizing this unit, consider the neighboring bores: the 40mm variant yields 527.8N at 0.5MPa, and the 63mm variant yields 1401.5N at 0.5MPa. This 50mm model provides a balanced 824.6N both ways. If your application requires less reach, a single-rod ACQ offers a more compact footprint, or a guided TACQ fits better for high side loads. To order, confirm the 250mm made-to-order stroke, PT1/4 ports, and the male M18x1.5 rod threads. Note that this unit lacks a sensor magnet.
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 ACQD50X250B FAQ
The push and pull forces are equal at 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum of 168kgf at 1.0MPa. Push equals pull because the twin rods create identical annular areas on both sides. The 250mm stroke is a long-stroke made-to-order variant exceeding the 100mm standard max. It features PT1/4 ports and male M18x1.5 rod-end threads.
It uses fixed NBR elastomer bumpers at both ends to absorb impact, which are not adjustable air cushions. A plain ACQD does not hold its load if air pressure is lost or the valve is centered; the rod will drift. For fail-safe holding, you must add an external rod lock or pilot-operated check valve.
