Airtac ACQD Double Acting Compact Cylinder ACQD63X20SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X20SB 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 ACQD63X20SB
The AirTAC ACQD63X20SB is a JIS compact, double-acting cylinder featuring twin Ø20mm rods exiting both ends. Because a rod occupies each chamber, the annular area remains identical in both directions, 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 balanced cycling operations.
The dual-rod architecture inherently resists rotation and extends the guide length, allowing a tool platform to mount directly without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. Equipped with the -S magnet for reed or solid-state switches and a -B male M18x1.5 thread for direct coupling, it uses fixed NBR bumpers for end-of-stroke deceleration rather than adjustable cushions.
Airtac ACQD Double Acting Compact Cylinder ACQD63X20SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X20SB |
|---|---|
| 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 ACQD63X20SB Is Used
Twin-Guided Pusher
Drives a wide format web-splicing blade in a paper mill, using both rods to prevent yaw without an external guide rail.
Symmetric Transfer
Actuates a dual-clamp arm on a CNC lathe loader, utilizing the equal push and pull forces to move parts smoothly in both directions.
Dual-Station Actuation
Powers a secondary stamping head on an automated assembly line, mounting the tool to the male M18x1.5 thread while the opposite rod carries a sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X20SB the Right Cylinder?
At 0.5MPa, this 63mm bore generates 1401.5N of force both ways. If less thrust is needed, the 50mm bore provides 824.6N, or for heavier loads, the 80mm bore offers 2267.8N. Choose this double-rod ACQD model when torsional stability or a two-sided drive is required; a single-rod ACQ is better for basic unguided pushing. Confirm your porting (PT1/4) and the M18x1.5 male rod thread when 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 ACQD63X20SB FAQ
The cylinder provides equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum holding capacity of 286kgf at 1.0MPa. Push and pull forces are identical because the twin rods create equal annular areas in both chambers. The standard stroke max for this 63mm bore is 100mm, and it features a male M18x1.5 rod-end thread.
No, a plain ACQD cylinder will drift if air pressure is lost or the valve is centered, as the fixed NBR bumpers only decelerate the piston near the stroke ends and do not lock the rod. For fail-safe vertical load holding, you must install an external rod lock or a pilot-operated check valve in the air circuit.
