Airtac ACQD Double Acting Compact Cylinder ACQD50X50H
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X50H 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 ACQD50X50H
The AirTAC ACQD50X50H is a double-acting JIS compact cylinder featuring twin rods that exit both ends of the body. Because a rod occupies both internal chambers, the effective annular area remains identical in either direction. This yields equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, ensuring symmetric thrust for advancing and retracting cycles.
Two protruding shafts drastically increase guide length and resist torsional deflection, allowing you to mount a tooling platform directly without needing an external anti-rotation guide. The unit uses a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. It features a PT1/4 port, a 20mm piston rod with a female M10x1.5 thread, and operates smoothly between 30-500mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD50X50H Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X50H |
|---|---|
| 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 ACQD50X50H Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer mechanism in packaging machinery, utilizing the equal push and pull thrust to move cartons consistently in both directions without force discrepancies.
Twin-Guided Stamping Platform
Carries a small marking stamp on a CNC machining center, leveraging the extended guide length of the two rods to prevent rotational play during precise metal embossing.
Dual-Station Actuation
Actuates a secondary component or sensor flag from the rear rod end on an automated assembly line, synchronizing two processes simultaneously from one compact body.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X50H the Right Cylinder?
Selecting this 50mm bore provides 824.6N of thrust both ways. If your application requires less force, the adjacent 40mm bore yields 527.8N; if you need more power, stepping up to the 63mm bore provides 1401.5N at 0.5MPa. A single-rod ACQ cylinder is preferable if you only need unidirectional thrust or have spatial constraints on one side, while a guided TACQ module is better for absorbing heavy lateral loads. To order, confirm the 50mm stroke, female M10x1.5 rod-end threads, and PT1/4 porting.
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 ACQD50X50H FAQ
The cylinder delivers an equal push and pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum capacity of 168kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 50mm bore is 100mm.
No, a plain ACQD does not maintain position upon air loss or valve centering; the rod will drift. The fixed NBR elastomer bumpers only decelerate the load near the stroke ends and do not act as a brake. For fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve.
