Airtac ACQD Double Acting Compact Cylinder ACQD63X20S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X20S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 20mm 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 ACQD63X20S
The AirTAC ACQD63X20S is a double-acting JIS compact cylinder featuring twin rods that exit both ends of the riveted body. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 1401.5 N at 0.5 MPa. This 63mm bore actuator provides substantial thrust without needing an external anti-rotation guide.
It includes a built-in magnet for electronic or reed switch sensing in the dedicated grooves. Fixed NBR elastomer bumpers absorb impact at both stroke ends, while the Ø20mm rods feature M10x1.5 female thread ends and a PT1/4 port. The extra guide length prevents platform twist during short 20mm transfers.
Airtac ACQD Double Acting Compact Cylinder ACQD63X20S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X20S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 20 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 ACQD63X20S Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place head in packaging machinery, using the equal push and pull forces to move products consistently in both directions without torque skew.
Twin-Guided Pusher
Pushes electronic components onto a testing fixture in an SMT line, where the twin rods prevent the tooling plate from rotating during the 20mm clamping action.
Dual-Station Actuation
Actuates a secondary reject gate via the rear rod end on a conveyor system while the front rod end performs the primary sorting push, saving space and extra hardware.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X20S the Right Cylinder?
Providing 1401.5 N of thrust at 0.5 MPa, this 63mm bore unit sits between the 50mm bore (824.6 N) and the 80mm bore (2267.8 N). Choose the ACQD63X20S when your application requires symmetric push/pull cycles and resistance to torsion within a 20mm stroke. If your mechanism only needs force in one direction, a single-rod ACQ cylinder offers a lighter footprint. For loads requiring precise lateral alignment over longer strokes, a guided TACQ cylinder might be preferable. Ensure you specify the -S magnet option for sensing, the PT1/4 port thread, and the M10x1.5 female rod ends.
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 ACQD63X20S FAQ
The cylinder delivers an equal push and pull force of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, with a maximum holding capacity of 286 kgf at 1.0 MPa. Forces are identical both ways due to equal annular areas on both sides of the piston. The standard stroke is 20mm, the operating pressure range is 0.15-1.0 MPa, and the port size is PT1/4.
No, a plain ACQD cylinder will drift and cannot hold position if air is lost; an external rod lock or pilot-operated check valve is required for fail-safe load holding. For impact, it uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. For high-energy cycles, add an external shock absorber or slow the approach speed.
