Airtac ACQD Double Acting Compact Cylinder ACQD40X45
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD40X45 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø40mm 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 ACQD40X45
The AirTAC ACQD40X45 is a double-acting JIS compact cylinder with twin rods extending 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 527.8N at 0.5MPa and 738.9N at 0.7MPa. The 40mm bore uses a PT1/8 port and a 16mm piston rod with a female M8x1.25 end.
This riveted C-clip body relies on fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. The dual-rod architecture inherently resists torsion and lengthens guide support, allowing you to mount a tooling plate directly without needing an external anti-rotation guide. The second protruding rod can also drive a sensor flag or secondary load.
Airtac ACQD Double Acting Compact Cylinder ACQD40X45 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD40X45 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 45 mm |
| Acting type | Double acting, double rod |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | 739 N |
| Max (@1.0 MPa) | 108 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 ACQD40X45 Is Used
Twin-Guided Pusher
Drives a flat pick-and-place head in packaging machinery, using the dual rods to prevent yaw without an external guide rail.
Symmetric Transfer
Executes balanced advance and retract motions on an electronic component handler, leveraging identical push and pull forces for stable cycling.
Dual-Station Actuation
Indexes a tooling plate between two machining stations, using the opposite rod end to trip an external limit switch.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD40X45 the Right Cylinder?
For a 45mm stroke, this 40mm bore provides 527.8N of thrust both ways. If your payload is lighter, the 32mm bore yields 301.6N and saves space, while the 50mm bore steps up to 824.6N for heavier tooling. Choose a single-rod ACQ if equal force is irrelevant and you need maximum unobstructed extension. Select a guided TACQ when lateral loads exceed what the twin rods can support. Confirm your rod-end thread (female M8x1.25 standard) and PT1/8 porting before 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 ACQD40X45 FAQ
It generates equal push and pull forces of 527.8N at 0.5MPa and 738.9N at 0.7MPa, with a maximum kgf of 108 at 1.0MPa. Push and pull match because the twin rods create the same annular area in both chambers. The maximum standard stroke for this 40mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends to absorb impact, not adjustable air cushions. It does not include a magnet for sensors. A plain ACQD does not hold position on air loss; for fail-safe load holding, you must add an external rod lock or pilot-operated check valve.
