Airtac ACQD Double Acting Compact Cylinder ACQD63X175SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X175SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 175mm 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 ACQD63X175SB
The AirTAC ACQD63X175SB is a double-acting, double-rod JIS compact cylinder featuring a 63mm bore and a 175mm stroke. Because twin rods exit both ends, the annular piston area is identical in each direction, yielding perfectly equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This symmetric thrust is ideal for precision cycles requiring balanced bi-directional force. A 175mm stroke exceeds the 100mm standard, making this a made-to-order long-stroke variant.
Twin Ø20mm rods 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 unit includes a male M18x1.5 rod-end thread for direct coupling, PT1/4 ports, and a piston magnet (-S) compatible with reed or solid-state switches. NBR bumpers fixed at both ends absorb impact energy.
Airtac ACQD Double Acting Compact Cylinder ACQD63X175SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X175SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 175 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 ACQD63X175SB Is Used
Symmetric Transfer Station
Drives a dual-sided pick-and-place mechanism in packaging machinery, using the equal push and pull thrust to maintain stable dynamics while shifting products between conveyors.
Twin-Guided Pusher
Executes long-stroke pushing on a material handling line where the dual rods prevent jaw rotation, eliminating the space and cost of a separate external guide rail.
Dual-Station Actuation
Powers a secondary tooling platform on a CNC lathe loader, using the extra rod end to mount a sensor flag while driving a secondary ejector load simultaneously.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X175SB the Right Cylinder?
Selecting this 63mm bore yields 286kgf max thrust at 1.0MPa. If your application needs less force, the adjacent 50mm bore provides 824.6N at 0.5MPa; for heavier loads, the 80mm bore offers 2267.8N at 0.5MPa. If you do not require equal bidirectional force or anti-rotation, a single-rod ACQ cylinder is more compact. For applications demanding high lateral load support without external guides, a guided TACQ cylinder fits better. To order, confirm the 175mm stroke, PT1/4 port, and M18x1.5 male 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 ACQD63X175SB FAQ
The push and pull forces are equal at 1401.5N @0.5MPa and 1962.2N @0.7MPa, with a maximum of 286kgf @1.0MPa. Equality exists because the double-rod design presents the same annular area in both directions. The 175mm stroke is a made-to-order long-stroke variant, exceeding the 100mm standard maximum for this 63mm bore.
Twin rods resist rotation and extend guide length. Fixed NBR bumpers at both ends absorb end-of-stroke impact, though external shock absorbers are recommended for high-energy approaches. A plain ACQD does not hold position on air loss; for fail-safe load holding, install an external rod lock or pilot-operated check valve.
