Airtac ACQD Double Acting Compact Cylinder ACQD63X20
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X20 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 ACQD63X20
The AirTAC ACQD63X20 is a double-acting JIS compact cylinder featuring a twin-rod design where a piston rod protrudes from both ends. 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 0.5MPa and 1962.2N at 0.7MPa. This symmetry is ideal for applications requiring consistent bi-directional power.
Two Ø20mm rods exiting the body significantly increase guide length and resist torsional deflection without needing an external guide. The unit operates at 30-500mm/s and relies on fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. It features a PT1/4 port and a female M10x1.5 rod-end thread, while the secondary rod end can conveniently drive a second load or mechanism.
Airtac ACQD Double Acting Compact Cylinder ACQD63X20 Technical Specifications

| 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 ACQD63X20 Is Used
Symmetric Transfer Arm
Drives a pick-and-place arm where the second rod end mounts a counterweight, ensuring balanced motion across packaging lines.
Twin-Guided Pusher
Pushes heavy pallets on a conveyor system where the dual rods prevent yawing and maintain precise alignment.
Dual-Station Actuation
Operates two separate forming dies simultaneously from opposite rod ends in an automotive stamping machine.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X20 the Right Cylinder?
Selecting this 63mm bore provides a robust 1401.5N force both ways at 0.5MPa. If your application requires less force, stepping down to a 50mm bore yields 824.6N; conversely, scaling up to an 80mm bore provides 2267.8N. Consider a single-rod ACQ if you only need unidirectional thrust and want to save space, or a guided TACQ cylinder if your load exceeds the anti-rotation capacity of the twin rods. This specific configuration ships without a sensor magnet, uses default PT port threading, and has a female M10x1.5 rod end.
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 ACQD63X20 FAQ
This 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 rod occupies both chambers, creating equal annular areas. The maximum standard stroke available for this 63mm bore is 100mm.
The twin-rod design inherently resists rotation and provides a longer guide length, eliminating the need for an external anti-rotation guide. End-of-stroke deceleration is handled by fixed NBR elastomer bumpers at both ends, which are not adjustable. Note that this specific model ships without a sensor magnet, though the body retains grooves for mounting reed or solid-state switches.
