Airtac ACQD Double Acting Compact Cylinder ACQD50X5S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X5S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 5mm 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 ACQD50X5S
The AirTAC ACQD50X5S is a double-acting JIS compact cylinder where a piston rod extends from both ends of the body. Because a rod occupies each chamber, the 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 symmetry is ideal for applications requiring perfectly balanced bi-directional cycles.
Twin rods provide extended guide length and high torsional resistance, allowing you to mount a small tool platform directly without needing an external anti-rotation guide. The 50mm bore uses a PT1/4 port and a 20mm diameter rod. This -S variant includes a piston magnet for position sensing, compatible with both reed and solid-state switches. Fixed NBR bumpers absorb impact at stroke ends, and the second rod end can drive a sensor flag or a secondary load.
Airtac ACQD Double Acting Compact Cylinder ACQD50X5S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X5S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 5 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 ACQD50X5S Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer carriage on packaging lines where equal push and pull force prevents load shifting during rapid direction changes.
Twin-Guided Tooling Platform
Mounts a small machining or clamping head directly to the twin rods on CNC loaders, using the extended guide length to resist torsional deflection.
Dual-Station Actuation
Uses the second protruding rod end to trigger a mechanical flag or secondary mechanism on a textile machine while the primary end executes the main work stroke.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X5S the Right Cylinder?
This 50mm bore generates 824.6N of force both ways. If your application requires less push, the 40mm bore provides 527.8N; for heavier demands, the 63mm bore offers 1401.5N at 0.5MPa. If you only need unidirectional thrust and can tolerate unequal return force, a single-rod ACQ cylinder may suffice. For loads exceeding the torsional limits of the twin rods, consider a guided TACQ series. To order, confirm the 5mm stroke, the -S magnet option, and the 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 ACQD50X5S FAQ
It delivers an equal push and pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum load capacity of 168kgf at 1.0MPa. Push and pull forces are identical because the rod occupies both chambers, creating the same annular area in each direction. The maximum standard stroke available for this 50mm bore is 100mm.
No, a plain ACQD does not hold position when air is lost; the rod will drift. The fixed NBR bumpers only decelerate the piston near the stroke ends and do not act as a brake. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
