Airtac ACQD Double Acting Compact Cylinder ACQD25X50B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X50B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm 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 ACQD25X50B
The AirTAC ACQD25X50B is a double-acting JIS compact cylinder featuring twin rods that exit from both ends of the riveted body. Because a piston rod occupies each chamber, the effective annular area is identical in both directions. This means the push and pull forces are perfectly equal at 188.9 N at 0.5 MPa and 264.5 N at 0.7 MPa, with a maximum output of 39 kgf at 1.0 MPa.
The dual-rod architecture inherently resists rotation and provides a longer guide length, allowing you to mount a small tool platform directly without needing an external anti-rotation guide. This specific variant includes a male M10x1.25 piston rod end for direct load coupling and a fixed TPU elastomer bumper at each end to absorb end-of-stroke impact. While it lacks a magnet, the body retains sensor grooves for adding switches later. It uses an M5x0.8 port and operates smoothly between 30-500 mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD25X50B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X50B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 50 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø25mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 189 N | 189 N |
| 0.7 MPa | 264 N | 264 N |
| Max (@1.0 MPa) | 39 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 ACQD25X50B Is Used
Symmetric Transfer Arms
Drives a pick-and-place arm where the second rod end simultaneously actuates a mechanical ejector, ensuring matched timing for both strokes on packaging lines.
Twin-Guided Pusher
Pushes small electronic components through a test fixture; the dual rods prevent chassis deflection and maintain precise alignment during high-speed cycling.
Dual-Station Actuation
Indexes a small dual-station machining fixture by driving a platform from both ends, keeping the tooling centered and resistant to rotational torque.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X50B the Right Cylinder?
For a 50 mm stroke, this 25 mm bore provides 188.9 N of equal bidirectional force at 0.5 MPa. If your application requires less force, stepping down to the 20 mm bore yields 117.8 N, while moving up to the 32 mm bore provides 301.6 N. Choose this ACQD twin-rod design when you need symmetric push/pull cycles and rotational stability without adding an external guide. If you only need standard single-rod extension with higher forward force, a standard ACQ cylinder is more appropriate. To order, confirm the 50 mm stroke, M5x0.8 port, and the male M10x1.25 rod 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 ACQD25X50B FAQ
Because the double-rod design uses the same annular area in both directions, push and pull forces are equal: 188.9 N at 0.5 MPa and 264.5 N at 0.7 MPa. The maximum output is 39 kgf at 1.0 MPa. The maximum standard stroke available for this 25 mm bore is 100 mm.
No, a plain ACQD does not hold its load when air is lost or the valve is centered; the rod will drift. The fixed TPU elastomer bumper only decelerates the piston near stroke end. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
