Airtac ACQD Double Acting Compact Cylinder ACQD63X175B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X175B 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 ACQD63X175B
The AirTAC ACQD63X175B is a double-acting JIS compact cylinder featuring twin rods that exit from both ends of the body. Because a rod occupies each chamber, the annular area is identical in both directions, yielding perfectly equal push and pull forces of 1401.5N at 0.5 MPa and 1962.2N at 0.7 MPa. The dual-rod architecture inherently resists rotation and provides an extended guide length, allowing it to carry a tool platform directly without needing an external anti-rotation guide.
This unit features a 175mm stroke, which exceeds the 100mm standard maximum for this bore, making it a made-to-order long-stroke variant. It includes the -B male rod-end thread (M18x1.5) for direct load coupling and uses a PT1/4 port. Fixed NBR elastomer bumpers at both ends absorb end-of-stroke impact, while the body retains magnetic-switch grooves, though this specific configuration ships without the internal magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD63X175B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X175B |
|---|---|
| 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 ACQD63X175B Is Used
Symmetric Transfer Arms
Drives long-reach pick-and-place arms in packaging lines where the 175mm travel and equal push/pull cycles prevent sagging or biased motion during product transfer.
Twin-Guided Pusher
Pushes heavy cartons on a conveyor system; the dual rods absorb lateral stress without twisting, eliminating the need for a separate external guide rail.
Dual-Station Actuation
Actuates two separate clamps or stations simultaneously from a single cylinder body, using both rod ends to drive independent tooling on an automated assembly machine.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X175B the Right Cylinder?
When sizing this 63mm bore, note the 1401.5N force at 0.5 MPa. If your application requires less force, the next size down (50mm) provides 824.6N, while stepping up to 80mm yields 2267.8N. Because this is a 175mm stroke—exceeding the 100mm standard max for bore 63—it is configured as a non-standard, made-to-order long-stroke unit. Choose a single-rod ACQ if equal bidirectional force is unnecessary, or a guided TACQ if your load exceeds the torsional limits of twin rods. Confirm the -B male M18x1.5 thread and PT1/4 port during ordering.
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 ACQD63X175B FAQ
It delivers an equal push and pull force of 1401.5N at 0.5 MPa and 1962.2N at 0.7 MPa, with a maximum force of 286 kgf at 1.0 MPa. Push and pull forces are identical because the rod occupies both chambers, making the effective annular area the same in each direction. The 175mm stroke is a non-standard, 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 decelerate the piston near stroke end; these are not adjustable air cushions. Additionally, a plain ACQD does not hold its load if air pressure is lost or the valve is centered, as the rod will drift. For fail-safe load holding, an external rod lock or pilot-operated check valve must be added to the system.
