Airtac ACQD Double Acting Compact Cylinder ACQD40X75B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD40X75B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø40mm bore and 75mm 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 ACQD40X75B
The AirTAC ACQD40X75B is a double-acting JIS compact cylinder where a 16mm rod protrudes from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 527.8N at 0.5MPa and 738.9N at 0.7MPa. The twin rods prevent rotation and extend guide length, allowing a tool platform to mount directly without external anti-rotation guides.
This 40mm bore unit features a PT1/8 port and a male M14x1.5 rod-end thread (-B) for direct load coupling. It uses fixed NBR elastomer bumpers at stroke ends rather than adjustable cushions. The body retains magnetic-switch grooves, but this specific configuration ships without a piston magnet. Standard stroke extends to 100mm, operating pressure spans 0.15-1.0MPa, and speed ranges 30-500mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD40X75B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD40X75B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 75 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 ACQD40X75B Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place head in packaging lines, using the matching push and pull forces to move components identically in both directions.
Twin-Guided Pusher
Pushes parts in CNC machining cells where the twin rods resist torsional loads and prevent jaw deflection without adding an external guide rail.
Dual-Station Actuation
Actuates two synchronized clamps in an assembly fixture, using the second rod end to drive a secondary mechanism or sensor flag simultaneously.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD40X75B the Right Cylinder?
At 0.5MPa, this 40mm bore generates 527.8N both ways. Dropping to a 32mm bore drops force to 301.6N, while stepping up to a 50mm bore increases it to 824.6N. Choose this size when matching those mid-range loads. If your application needs asymmetric push/pull forces, a single-rod ACQ fits better. If you need heavy lateral load capacity beyond twin-rod guidance, a guided TACQ series is recommended. Confirm the 75mm stroke, male M14x1.5 thread, and PT1/8 port 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 ACQD40X75B FAQ
Push and pull forces are equal due to the double-rod annular area: 527.8N at 0.5MPa and 738.9N at 0.7MPa, with a maximum of 108kgf at 1.0MPa. The maximum standard stroke for this 40mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends, not adjustable air cushions. A plain ACQD does not hold position on air loss; the rod drifts. For fail-safe holding, install an external rod lock or pilot-operated check valve.
