Airtac ACQD Double Acting Compact Cylinder ACQD50X70B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X70B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 70mm 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 ACQD50X70B
The AirTAC ACQD50X70B is a double-acting JIS compact cylinder featuring twin rods that exit both ends of its riveted body. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This 50mm bore design eliminates the force imbalance found in single-rod units, ensuring perfectly symmetric cycles.
The dual rods inherently resist rotation and provide a longer guide length, allowing you to mount a tooling platform directly without needing an external anti-rotation guide. This specific variant includes a male M18x1.5 rod-end thread for direct load coupling, PT1/4 supply ports, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. The body retains magnetic-switch grooves, though this unit ships without a piston magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD50X70B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X70B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 70 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 ACQD50X70B Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place head in electronics assembly, leveraging equal push/pull force to maintain consistent actuation speed in both directions without pressure tuning.
Twin-Guided Tool Platform
Carries a small machining spindle on a packaging line, using the dual rods to resist rotational torque and prevent platform deflection without adding an external linear guide.
Dual-Station Actuation
Powers a secondary cam or sensor flag from the opposite rod end on a textile machine, synchronizing two separate mechanisms from one compact 50mm body.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X70B the Right Cylinder?
For a 70mm stroke, this 50mm bore provides 824.6N of thrust both ways at 0.5MPa. If your payload is lighter, stepping down to the 40mm bore yields 527.8N, while moving up to the 63mm bore offers 1401.5N for heavier fixtures. Choose this twin-rod architecture over a single-rod ACQ when you need equal push/pull dynamics or cannot fit a separate external guide. Remember that a plain double-rod cylinder drifts when air is lost; for fail-safe holding, specify an external rod lock or pilot-operated check valve. Confirm you need the male M18x1.5 rod thread and PT1/4 porting 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 ACQD50X70B FAQ
The 50mm bore generates equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum holding capability of 168kgf at 1.0MPa. Push and pull forces are identical because the rod occupies both chambers, creating equal annular areas. This model has a 70mm stroke (max standard stroke is 100mm) and uses PT1/4 supply ports.
The twin rods inherently resist rotation and extend guide length, allowing direct tool mounting without an external guide rail. Deceleration is handled by fixed NBR elastomer bumpers at both ends, which are non-adjustable. The body features grooves for reed or solid-state switches, but this specific model ships without the -S piston magnet.
