Airtac ACQD Double Acting Compact Cylinder ACQD63X250
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X250 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm 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 ACQD63X250
The AirTAC ACQD63X250 is a double-acting JIS compact cylinder featuring a 63mm bore and a 250mm stroke. Because twin rods exit both ends, the annular piston area remains identical in each direction, yielding exactly 1401.5N of force at 0.5MPa and 1962.2N at 0.7MPa on both the extend and retract strokes. This symmetric thrust is ideal for balanced cycling, and the extra guide length resists torsional deflection without needing an external non-rotating guide.
Configured as a made-to-order long-stroke variant exceeding the 100mm standard maximum for this bore, it utilizes a 20mm rod with a female M10x1.5 end thread. NBR elastomer bumpers fixed at each end absorb end-of-travel impact, as no adjustable air cushion is present. While this specific unit omits the -S magnet, the body retains magnetic-switch grooves for adding reed or solid-state sensors later.
Airtac ACQD Double Acting Compact Cylinder ACQD63X250 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X250 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 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 (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 ACQD63X250 Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place head in electronics assembly, using the equal push and pull thrust to maintain stable indexing across a 250mm span.
Twin-Guided Pusher
Pushes heavy cartons on a packaging line where the extended guide length of the two rods prevents chassis yaw without needing a separate external guide bearing.
Dual-Station Actuation
Actuates a secondary clamping mechanism via the second protruding rod end on a machining center, synchronizing two separate workholding stations in one stroke.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X250 the Right Cylinder?
Selecting this 63mm bore involves sizing against adjacent options: a 50mm bore yields 824.6N, while an 80mm bore provides 2267.8N at 0.5MPa. This model fits applications needing roughly 1400N of symmetric thrust over an extended 250mm travel. If your mechanism only requires single-directional thrust, a standard single-rod ACQ provides a smaller footprint. For multi-axis loads requiring extreme side-load capacity, a guided TACQ might serve better. When ordering, confirm the PT1/4 port, female M10x1.5 rod thread, and the 250mm nonstandard stroke requirement.
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 ACQD63X250 FAQ
It delivers an equal push and pull force 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 rods occupy both chambers, creating identical annular areas. The 250mm stroke is a nonstandard long-stroke variant exceeding the 100mm standard maximum for this bore.
No, a plain ACQ-type cylinder will drift downward if air is lost or the valve is centered, as the fixed NBR bumpers only decelerate the piston near the stroke ends. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
