Airtac ACQD Double Acting Compact Cylinder ACQD50X70S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X70S 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 ACQD50X70S
The AirTAC ACQD50X70S is a double-acting JIS compact cylinder featuring twin rods that exit from 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. The Ø20mm rods provide a longer guide length to carry a small tool platform without needing an external anti-rotation guide.
This 50mm bore unit integrates a built-in piston magnet for position sensing, compatible with reed or solid-state electronic switches. It uses a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The second protruding rod end can drive a sensor flag or synchronize a secondary load, making it highly versatile for symmetric automation cycles.
Airtac ACQD Double Acting Compact Cylinder ACQD50X70S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X70S |
|---|---|
| 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 ACQD50X70S Is Used
Symmetric Transfer Pusher
Drives a dual-sided parts pusher in packaging machinery, utilizing the equal push and pull force to shuttle products smoothly in both directions without stroke bias.
Dual-Station Actuation
Powers two independent workstations simultaneously from a single actuator body, using both rod ends to index separate tooling platforms on an assembly carousel.
Twin-Guided Press Tool
Deploys a small stamping or clamping head in electronics manufacturing, relying on the twin rods to resist torsional loads and prevent binding during vertical press operations.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X70S the Right Cylinder?
When sizing this 50mm bore actuator, consider the neighboring capacities: the 40mm bore provides 527.8N, while the 63mm bore offers 1401.5N, both at 0.5MPa. If your application only requires unidirectional thrust and lacks space for twin rods, a single-rod ACQ cylinder is a better fit. For processes demanding precise multi-axis motion without torsional deflection, a guided TACQ cylinder provides superior stability. Confirm your ordering essentials: this ACQD50X70S configuration includes a 70mm stroke, a -S magnet for electronic or reed switches, a standard PT1/4 port, and a female M10x1.5 rod-end thread.
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 ACQD50X70S FAQ
It delivers an equal push and pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum holding capacity of 168kgf at 1.0MPa. Push and pull forces are identical because the twin-rod design creates the same effective annular area in both chambers. The maximum standard stroke available for this 50mm bore is 100mm.
A plain ACQD does not hold position on air loss; the rod drifts and requires an external rod lock or pilot-operated check valve for fail-safe holding. For impact handling, it uses a fixed NBR elastomer bumper at each end rather than an adjustable air cushion. For high-energy cycles, you should slow the approach speed or add an external shock absorber.
