Airtac ACQD Double Acting Compact Cylinder ACQD50X50
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X50 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 50mm 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 ACQD50X50
The AirTAC ACQD50X50 is a double-acting JIS compact cylinder featuring twin rods extending from both ends. Because a piston rod occupies each internal chamber, the annular area remains identical in either direction, generating equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This symmetry is ideal for applications requiring perfectly balanced bi-directional cycles.
The dual-rod architecture inherently resists rotation and provides an extended guide length, allowing a tool platform to be mounted directly without needing an external anti-rotation guide. This 50mm bore unit uses a PT1/4 port, a Ø20mm piston rod, and a fixed NBR elastomer bumper at each end for end-of-stroke deceleration. The second protruding rod end can drive a sensor flag or a secondary load simultaneously.
Airtac ACQD Double Acting Compact Cylinder ACQD50X50 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X50 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 50 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 ACQD50X50 Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place arm in electronics assembly, using equal bi-directional force to push and pull components without stroke imbalance.
Twin-Guided Pusher
Indexes cartons on a packaging conveyor where the twin rods prevent platform twisting under offset loads without needing an external guide rail.
Dual-Station Actuation
Actuates two separate clamp stations simultaneously on an automotive fixture, utilizing both protruding rod ends to drive independent mechanisms.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X50 the Right Cylinder?
Providing 824.6N of force at 0.5MPa, this 50mm bore unit sits between the 40mm bore (527.8N) and the 63mm bore (1401.5N) options, making it a solid mid-range choice for moderate payloads. If your application only requires unidirectional pushing, a single-rod ACQ cylinder offers greater forward thrust. For high kinetic energy at stroke ends, pair this cylinder with an external shock absorber since the built-in elastomer bumper is fixed. This specific configuration ships without a magnet (no -S suffix) and features a default 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 ACQD50X50 FAQ
The ACQD50X50 generates equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum holding capacity of 168kgf at 1.0MPa. Because a rod exits both ends, the annular piston area is identical in each direction, making push and pull forces perfectly equal. The maximum standard stroke available for this 50mm bore is 100mm.
No, a plain ACQD does not hold its load when air is lost; the rod will drift and the fixed NBR bumper only decelerates near the stroke end. For fail-safe load holding, an external rod lock or pilot-operated check valve is required. Additionally, this specific model ships without a magnet, though the body retains sensor grooves for external switches.
