Airtac ACQD Double Acting Compact Cylinder ACQD50X30S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X30S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 30mm 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 ACQD50X30S
The AirTAC ACQD50X30S is a double-acting JIS compact cylinder featuring a 50mm bore and 30mm stroke. Because twin rods protrude from both ends, the effective annular area remains identical in each direction. This yields perfectly equal push and pull forces of 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa, enabling highly symmetric cycle movements without any differential thrust.
Twin rods inherently resist torsion and add guiding 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. Built with a fixed NBR elastomer bumper at each end, it safely decelerates the payload. The integrated -S piston magnet works seamlessly with reed or solid-state electronic switches.
Airtac ACQD Double Acting Compact Cylinder ACQD50X30S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X30S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 30 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 ACQD50X30S Is Used
Symmetric Transfer Assembly
Drives a dual-sided pick-and-place head in electronics manufacturing, using the equal push/pull force to maintain perfectly balanced positioning during component transfer.
Twin-Guided Pusher
Acts as a compact part pusher on a conveyor line, leveraging the dual-rod anti-rotation design to keep the tooling plate perfectly straight without needing an external guide rail.
Dual-Station Actuation
Powers a dual-station clamping fixture in packaging machinery, using the second rod end to trigger a solid-state sensor flag while securely holding the carton.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X30S the Right Cylinder?
Selecting this 50mm bore yields 824.6N of thrust both ways. If your payload is lighter, step down to the 40mm bore which provides 527.8N at 0.5 MPa. For heavier demands, the 63mm bore offers 1401.5N at 0.5 MPa. If your application requires unequal push/pull mechanics, a single-rod ACQ cylinder is a better fit. When ordering, confirm the 30mm stroke, PT1/4 port, and the default female M10x1.5 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 ACQD50X30S FAQ
This double-acting cylinder generates an equal push and pull force of 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa, with a maximum load capacity of 168 kgf at 1.0 MPa. Because the twin rods occupy both chambers, the annular area is identical in both directions, making the thrust perfectly symmetric. The maximum standard stroke available for this 50mm bore is 100mm.
The dual rods provide inherent resistance to torsion and extend the guiding length. It uses fixed NBR elastomer bumpers at stroke ends for deceleration rather than adjustable air cushions. Note that a plain ACQD does not hold position when air is lost; for fail-safe load holding, you must install an external rod lock or pilot-operated check valve.
