Airtac ACQD Double Acting Compact Cylinder ACQD63X35S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X35S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 35mm 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 ACQD63X35S
The AirTAC ACQD63X35S is a double-acting JIS compact cylinder featuring twin rods that exit from both body ends. Because a rod occupies each chamber, the annular areas match, yielding identical push and pull forces of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. The symmetrical layout is ideal for balanced actuation cycles. It includes a built-in magnet (-S) for position sensing.
Twin rods significantly increase guide length and resist torsional loads without needing an external guide rail. The second rod end can drive a sensor flag or a secondary tool platform. Fixed NBR elastomer bumpers absorb impact at stroke extremes, operating effectively within a 0.15-1.0 MPa pressure range and 30-500 mm/s speed limits. Note that this cylinder does not inherently hold its load if air pressure is lost; an external rod lock or pilot check valve is required for fail-safe positioning.
Airtac ACQD Double Acting Compact Cylinder ACQD63X35S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X35S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 35 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 ACQD63X35S Is Used
Symmetric Transfer Pusher
Drives a dual-sided pusher in packaging lines, utilizing the equal push and pull forces to move cartons smoothly in both directions without force imbalance.
Twin-Guided Pick-and-Place
Handles electronic components on a PCB assembly machine, where the extended guide length of the two rods prevents jaw twist during vertical lifting.
Dual-Station Actuation
Powers a dual-station clamping mechanism in automotive parts machining, using the second protruding rod end to trigger a mechanical valve or secondary stop.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X35S the Right Cylinder?
For this 63mm bore, the equal bidirectional force is 1401.5 N at 0.5 MPa (1962.2 N at 0.7 MPa). If your application requires less force, step down to the 50mm bore providing 824.6 N at 0.5 MPa. If you need more power, the 80mm bore offers 2267.8 N at 0.5 MPa. If rotational resistance is unnecessary and space is tight, a single-rod ACQ cylinder may suffice. When ordering, confirm the 35mm stroke, PT1/4 port, and the default female M10x1.5 rod-end thread. The -S suffix ensures compatibility with both reed and solid-state electronic switches.
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 ACQD63X35S FAQ
The cylinder provides equal push and pull forces 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. Push and pull forces are identical because the twin rods create equal annular areas on both sides of the piston. The operating pressure is 0.15-1.0 MPa, and the maximum standard stroke available for this 63mm bore is 100mm.
The dual-rod design inherently resists rotation and extends the guide length, eliminating the need for an external anti-rotation guide. It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, which are not adjustable. The -S option includes a piston magnet that works seamlessly with both reed switches and solid-state electronic sensors mounted in the standard grooves.
