Airtac ACQD Double Acting Compact Cylinder ACQD63X125SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X125SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 125mm 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 ACQD63X125SB
The AirTAC ACQD63X125SB is a double-acting JIS compact cylinder featuring a twin-rod design where a Ø20mm piston rod protrudes from both body ends. Because a rod occupies both internal chambers, the effective annular area is identical in each direction. This yields perfectly equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, enabling symmetric cycle movements without the force differential found in single-rod units.
Configured with a 125mm stroke, this is a made-to-order long-stroke variant exceeding the 100mm standard maximum for this bore. The twin rods inherently resist rotation and extend the guide length, allowing a tool platform to be carried directly without needing an external anti-rotation guide. It includes a male M18x1.5 rod-end thread for direct load coupling, a PT1/4 port, and a built-in magnet (-S) for electronic or reed switches. Fixed NBR elastomer bumpers absorb end-of-stroke impact.
Airtac ACQD Double Acting Compact Cylinder ACQD63X125SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X125SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 125 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 (Ø63mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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 ACQD63X125SB Is Used
Symmetric Transfer Unit
Drives a dual-sided parts shuttle in packaging machinery, utilizing the equal push and pull forces to maintain perfectly balanced indexing in both travel directions.
Twin-Guided Pusher
Deploys a machining fixture clamp without an external guide rail, relying on the two protruding rods to resist torsional stress and prevent platform rotation.
Dual-Station Actuation
Operates two separate workstations simultaneously from a single body, using the second rod end to drive a secondary mechanism or a sensor flag on an automated assembly line.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X125SB the Right Cylinder?
Selecting this 63mm bore provides 1401.5N of thrust both ways at 0.5MPa. If your application requires less force, stepping down to a 50mm bore yields 824.6N, while moving up to an 80mm bore provides 2267.8N. If anti-rotation is unnecessary and a shorter depth is critical, a standard single-rod ACQ cylinder might fit better. Conversely, if heavy side loads exceed the twin-rod guide capacity, a TACQ guided cylinder is recommended. Confirm your ordering essentials: this ACQD63X125SB specifies the 63x125 size, -S magnet, and -B male M18x1.5 rod 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 ACQD63X125SB FAQ
This cylinder provides equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum capacity of 286kgf at 1.0MPa. Push equals pull because the rod occupies both chambers, creating identical annular areas. The 125mm stroke is a made-to-order long-stroke variant, as the standard maximum for a 63mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends to absorb impact, which are not adjustable air cushions. For high-speed approaches, an external shock absorber is recommended. A plain ACQD does not hold position when air is lost; if fail-safe load holding is required, you must add an external rod lock or pilot-operated check valve.
