Airtac ACQD Double Acting Compact Cylinder ACQD63X45B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X45B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 45mm 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 ACQD63X45B
The AirTAC ACQD63X45B is a double-acting JIS compact cylinder featuring a 63mm bore and a 45mm stroke. Because twin piston rods exit both ends of the C-clip riveted body, the effective annular area is identical in each direction. This yields perfectly equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, enabling symmetric cycles without force mismatch.
The dual rods inherently resist rotation and provide a longer guide length, allowing you to mount a tool platform directly without needing an external anti-rotation guide. This specific unit includes a male M18x1.5 rod-end thread for direct load coupling and PT1/4 ports. It uses fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions, and while the body retains sensor grooves, this variant ships without a magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD63X45B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X45B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 45 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 ACQD63X45B Is Used
Symmetric Transfer Unit
Drives a dual-sided parts shuttle in packaging machinery, using the equal push and pull forces to maintain stable conveying without momentum shifts.
Twin-Guided Pusher
Mounts a tooling head directly to the rods on an CNC loading station, leveraging the anti-rotation properties to push parts without a separate guide rail.
Dual-Station Actuation
Operates two independent clamps simultaneously from a single actuator in an automotive assembly fixture, utilizing the second rod end to drive a secondary mechanism.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X45B the Right Cylinder?
Selecting this 63mm bore provides 1401.5N of thrust at 0.5MPa. If your application requires less force, stepping down to the 50mm bore yields 824.6N at 0.5MPa. For heavier demands, the 80mm bore provides 2267.8N at 0.5MPa. If you only need unidirectional thrust where push exceeds pull, a single-rod ACQ cylinder is a simpler choice. For applications needing precise non-rotating guidance over a longer span, a guided TACQ cylinder might fit better. When ordering, confirm the 45mm stroke, the male M18x1.5 rod thread, and PT1/4 porting.
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 ACQD63X45B FAQ
The push and pull forces are equal at 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum force of 286kgf at 1.0MPa. The equal force occurs because the rods occupy both chambers, creating identical annular areas. The stroke is 45mm, the maximum standard stroke for a 63mm bore is 100mm, and the operating pressure range is 0.15-1.0MPa.
It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, not adjustable air cushions. A plain ACQ-type cylinder does not hold its load if air is lost, as the rod will drift and the bumper only decelerates near the stroke end. For fail-safe load holding, an external rod lock or pilot-operated check valve is required.
