Airtac ACQD Double Acting Compact Cylinder ACQD50X75B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X75B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm 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 ACQD50X75B
The AirTAC ACQD50X75B is a double-acting JIS compact cylinder where a Ø20mm piston rod exits both ends. Because a rod occupies each chamber, the annular areas match, yielding identical push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This model includes a male M18x1.5 rod-end thread for direct load coupling and uses PT1/4 ports.
Twin rods inherently resist rotation and extend the guide length, letting you mount a tool platform without needing a separate external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. Deceleration relies on fixed NBR elastomer bumpers at both ends, not adjustable air cushions. Note that this specific unit ships without a magnet, though the body retains magnetic-switch grooves for adding sensors later if needed.
Airtac ACQD Double Acting Compact Cylinder ACQD50X75B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X75B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 75 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 (Ø50mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 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 ACQD50X75B Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place shuttle in packaging lines, utilizing the equal push and pull forces to maintain balanced cycle times in both directions.
Twin-Guided Tooling Platform
Carries a small machining head on a CNC router, relying on the twin rods to prevent rotational drift without installing a separate external guide rail.
Dual-Station Actuation
Powers a multi-position ejection mechanism on an assembly machine, using the second protruding rod end to trigger a physical sensor flag for part confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X75B the Right Cylinder?
At 0.5MPa this 50mm bore delivers 824.6N both ways. If you need less force, the 40mm bore provides 527.8N, or for heavier demands the 63mm bore offers 1401.5N. If your application requires true fail-safe load holding upon air loss, remember a standard ACQD drifts; you must add an external rod lock or pilot check valve. When ordering, confirm the 75mm stroke, the male M18x1.5 thread (-B), and PT1/4 porting to match your setup.
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 ACQD50X75B FAQ
It delivers equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum force of 168kgf at 1.0MPa. Push and pull are identical because the twin rods create equal annular areas on both sides. The standard stroke max is 100mm, this unit is 75mm. It features a male M18x1.5 rod thread and PT1/4 ports.
It uses fixed NBR elastomer bumpers at both stroke ends for impact absorption, not adjustable air cushions. For high kinetic energy loads, add an external shock absorber. A plain ACQD does not hold its position when air is lost; the rod drifts, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
