Airtac ACQD Double Acting Compact Cylinder ACQD50X90
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X90 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 90mm 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 ACQD50X90
The AirTAC ACQD50X90 is a double-acting JIS compact cylinder where a rod protrudes from both ends. Because the twin rods occupy both internal chambers, the effective annular area is identical in either direction, yielding perfectly equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This symmetry is ideal for applications needing identical motion dynamics in both travel directions.
The dual-rod architecture inherently resists torsional rotation and extends the guide length, allowing you to mount a tooling platform directly without adding a separate external anti-rotation guide. It features fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. This specific unit has a 50mm bore, a 90mm stroke, PT1/4 ports, and ships without a magnet, though the body retains sensor grooves for adding external reed or solid-state switches.
Airtac ACQD Double Acting Compact Cylinder ACQD50X90 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X90 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 90 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 ACQD50X90 Is Used
Symmetric Transfer Shuttle
Drives a parts shuttle on a packaging machine where matching push and pull forces ensure identical cycle times and smooth handoff in both directions.
Twin-Guided Pick & Place
Carries a vertical gripper assembly on an electronics line, using the extended guide length to prevent jaw deflection without a separate external guide rail.
Dual-Station Actuation
Powers a dual-station press in metal stamping where one rod end moves the primary tool and the opposite end triggers an external solid-state sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X90 the Right Cylinder?
This 50mm bore unit delivers 824.6N of force both ways. If you need less force, the 40mm bore provides 527.8N; if you require more, the 63mm bore offers 1401.5N. Choose this double-rod model over a single-rod ACQ when your mechanism demands built-in rotational resistance or a second rod end to mount a sensor flag. Remember that a plain ACQD does not hold its load if air pressure drops, so integrate an external rod lock or pilot check valve for fail-safe positioning. Confirm you need the default female M10x1.5 rod-end thread and the standard PT1/4 port 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 ACQD50X90 FAQ
The ACQD50X90 provides equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum holding capability of 168kgf at 1.0MPa. Push and pull forces are identical because the twin rods create the same effective annular area in both chambers. The maximum standard stroke available for this 50mm bore is 100mm.
No, it uses fixed NBR elastomer bumpers at both ends for end-of-stroke impact absorption rather than adjustable air cushions. Additionally, this specific configuration ships without a magnet, but the body includes grooves allowing you to mount external reed or solid-state switches directly.
