Airtac ACQD Double Acting Compact Cylinder ACQD50X35
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X35 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 35mm 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 ACQD50X35
The AirTAC ACQD50X35 is a double-acting JIS compact cylinder where a Ø20mm piston rod protrudes from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding perfectly equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. The twin-rod architecture inherently resists rotation and extends guide length, allowing a tool platform to be carried directly without a separate external anti-rotation guide.
This 50mm bore unit features a PT1/4 port and a female M10x1.5 rod-end thread. It incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The body retains magnetic-switch grooves for tracking position, though this specific configuration ships without a magnet. Operating pressure spans 0.15-1.0MPa, with a maximum standard stroke capacity of 100mm for this bore size.
Airtac ACQD Double Acting Compact Cylinder ACQD50X35 Technical Specifications

| Stroke | 35 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 ACQD50X35 Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place arm in packaging machinery, using the equal push and pull forces to ensure consistent cycle times in both directions.
Twin-Guided Pusher
Pushes parts in a CNC loading station where the twin rods prevent deflection and rotation without needing a bulky external guide rail.
Dual-Station Actuation
Actuates a secondary mechanism or sensor flag from the rear rod end on an assembly line while driving the primary workpiece from the front.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X35 the Right Cylinder?
Providing 824.6N of force both ways at 0.5MPa, this 50mm bore sits comfortably between the 63mm bore (1401.5N) and the 40mm bore (527.8N). Select this size when your application requires symmetric push/pull cycles and moderate force. If your cycle only needs force in one direction, a single-rod ACQ might offer a simpler footprint. For higher kinetic energy at stroke ends, consider an external shock absorber since the bumpers are fixed. Confirm the PT1/4 port and female M10x1.5 thread 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 ACQD50X35 FAQ
The push and pull forces are equal at 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum capacity of 168kgf at 1.0MPa. Push equals pull because the rod occupies both chambers, creating identical annular areas. The maximum standard stroke for a 50mm bore is 100mm.
No, a plain ACQD does not hold its load when air is lost or the valve is centered; the rod will drift. The fixed NBR bumpers only decelerate the motion near the stroke end. For fail-safe load holding, an external rod lock or pilot-operated check valve is required.
