Airtac ACQD Double Acting Compact Cylinder ACQD50X50S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X50S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 50mm 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 ACQD50X50S
The AirTAC ACQD50X50S is a double-acting JIS compact cylinder featuring twin rods that exit both ends of its riveted C-clip body. Because a rod occupies each chamber, the annular piston area is identical in both directions, yielding perfectly equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This symmetric thrust is ideal for precise bidirectional cycles.
The dual shafts inherently resist rotation and provide an extended guide length, allowing you to mount a tool platform directly 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, houses Ø20mm rods, and includes fixed NBR elastomer bumpers at each end for end-of-stroke deceleration. Equipped with the -S magnet, it supports both reed and solid-state switches.
Airtac ACQD Double Acting Compact Cylinder ACQD50X50S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X50S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 50 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 ACQD50X50S Is Used
Symmetric Transfer Arms
Drives dual-sided pick-and-place arms in packaging lines where equal push and pull forces keep horizontal product transfers perfectly balanced.
Twin-Guided Pusher
Acts as a twin-guided pusher on a conveyor sorting station, using the extended guide length to resist deflection without an external guide rail.
Dual-Station Actuation
Powers dual-station actuation on a PCB testing fixture, using the second rod end to trigger a solid-state sensor flag simultaneously.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X50S the Right Cylinder?
Select the ACQD50X50S for 50mm stroke applications needing 824.6N of equal bidirectional thrust. If your push cycle requires less force, the 40mm bore delivers 527.8N at 0.5MPa; for heavier symmetric loads, the 63mm bore provides 1401.5N. A single-rod ACQ is preferable if unequal push/pull forces are acceptable and space is tight. For ordering, confirm the 50mm bore, 50mm stroke, S magnet option, and default female M10x1.5 rod-end threads with PT1/4 ports.
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 ACQD50X50S FAQ
The ACQD50X50S operates between 0.15-1.0 MPa and provides an equal push and pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. The maximum standard stroke for this 50mm bore is 100mm. Push and pull forces are identical because the twin rods create the same effective annular area in both directions.
It uses fixed NBR elastomer bumpers at both ends for deceleration, not adjustable air cushions. A plain ACQD does not hold its load if air pressure is lost; the rod will drift. For fail-safe load holding, you must add an external rod lock or pilot-operated check valve.
