Airtac ACQD Double Acting Compact Cylinder ACQD50X300
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X300 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 300mm 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 ACQD50X300
The AirTAC ACQD50X300 is a double-acting JIS compact cylinder featuring a 50mm bore and a 300mm stroke. Because twin rods exit both ends, the annular piston area remains identical in each direction, yielding perfectly balanced thrust. You get 824.6N of force at 0.5MPa and 1154.5N at 0.7MPa for both extension and retraction, with a maximum capacity of 168kgf at 1.0MPa.
This 300mm travel variant is a made-to-order long-stroke unit, exceeding the 100mm standard maximum for this bore size. The Ø20mm rods use a female M10x1.5 end thread, while the body integrates PT1/4 ports and fixed NBR elastomer bumpers. Although the body retains magnetic-switch grooves, this specific configuration ships without a piston magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD50X300 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X300 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 300 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 ACQD50X300 Is Used
Symmetric Transfer Pusher
Drives a dual-sided pusher on a conveyor line, leveraging the equal push and pull forces to move packages smoothly in both directions without stroke imbalance.
Twin-Guided Stamping Tool
Operates a small stamping platform on an electronics production machine, using the two protruding rods to resist rotation and maintain tool alignment over the 300mm travel.
Dual-Station Actuation
Powers a dual-station testing fixture where the secondary rod end mounts a sensor flag, triggering a reed or solid-state switch to sequence operations on packaging equipment.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X300 the Right Cylinder?
For a 50mm bore, sizing neighbours are 40mm (527.8N) and 63mm (1401.5N) at 0.5MPa. If your application only needs one-sided actuation, a single-rod ACQ saves space; for heavy lateral loads, a guided TACQ provides better support. When ordering this 300mm long-stroke variant, confirm the female M10x1.5 rod thread and PT1/4 porting. Note that a standard ACQ-type will not hold a load if air pressure drops; install an external rod lock or pilot check valve for fail-safe positioning.
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 ACQD50X300 FAQ
It provides equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum load of 168kgf at 1.0MPa. Push equals pull because the twin rods create the same annular area both ways. The 300mm stroke is a made-to-order long-stroke variant, exceeding the 100mm standard maximum for a 50mm bore.
It uses fixed NBR elastomer bumpers at both ends to absorb impact energy, not adjustable air cushions. For high-speed approaches, an external shock absorber is recommended. A plain ACQ-type does not hold its load on air loss; you must add an external rod lock or pilot-operated check valve for fail-safe positioning.
