Airtac ACQD Double Acting Compact Cylinder ACQD50X75
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X75 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 75mm 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 ACQD50X75
The AirTAC ACQD50X75 is a double-acting JIS compact cylinder featuring a twin-rod design where a piston extends from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions. This means push and pull forces are perfectly equal at 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa. The dual rods inherently resist rotation and provide a longer guide length, allowing you to carry a small tool platform without needing a separate anti-rotation guide.
This 50 mm bore unit uses a PT1/4 port and a Ø20 mm piston rod with a female M10x1.5 rod-end thread. It shares the standard C-clip and riveted body construction, operating reliably between 0.15-1.0 MPa. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet. Note that a plain ACQD does not hold its load if air pressure is lost; an external rod lock or pilot check valve is required for fail-safe positioning.
Airtac ACQD Double Acting Compact Cylinder ACQD50X75 Technical Specifications

| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 75 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 ACQD50X75 Is Used
Symmetric Transfer Pusher
Drives a dual-sided clamping fixture in packaging machinery where equal 824.6 N push and pull forces prevent workpiece distortion during transit.
Twin-Guided Tooling Platform
Carries a machining head on CNC loaders, using the second rod end to mount a sensor flag while the twin rods prevent rotational drift.
Dual-Station Actuation
Indexes two separate conveyor stops simultaneously from one body, leveraging the dual protruding rods to actuate parallel stations in sync.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X75 the Right Cylinder?
Selecting this 75 mm stroke model provides 824.6 N of equal bidirectional force at 0.5 MPa. If your application requires less force, dropping to a 40 mm bore yields 527.8 N, whereas stepping up to a 63 mm bore provides 1401.5 N. This 50 mm bore is an excellent middle ground for medium-duty transfer. A single-rod ACQ fits better when pull force can be lower than push force, and a guided TACQ is preferable if you need heavy external torque resistance. To order, confirm the 75 mm stroke, the standard female M10x1.5 rod thread, and the default 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 ACQD50X75 FAQ
The ACQD50X75 has a 50 mm bore and a 75 mm stroke. Because it is a double-rod cylinder with equal annular area on both sides, push and pull forces are identical: 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa. The maximum standard stroke for this bore is 100 mm, and it can generate up to 168 kgf at 1.0 MPa.
Twin rods exiting both ends resist rotation and provide a longer guide length without needing an external guide. Deceleration at stroke ends is handled by fixed NBR elastomer bumpers, not adjustable air cushions. For high-speed or high-energy loads, you should add an external shock absorber or slow the approach speed.
