Airtac ACQD Double Acting Compact Cylinder ACQD25X70B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X70B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 70mm 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 ACQD25X70B
The AirTAC ACQD25X70B is a double-acting JIS compact cylinder featuring twin Ø12mm rods extending from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa. This symmetric thrust is ideal for balanced transfer cycles.
Equipped with male M10x1.25 rod-end threads, it couples directly to tooling platforms without needing an external anti-rotation guide. The body incorporates sensor grooves for reed or solid-state switches, though this specific unit ships without a magnet. Deceleration is handled by fixed TPU bumpers at both ends, and the M5x0.8 ports supply air efficiently within the 0.15-1.0MPa operating range.
Airtac ACQD Double Acting Compact Cylinder ACQD25X70B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X70B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 70 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 ACQD25X70B Is Used
Symmetric Transfer Shuttle
Drives a dual-sided parts shuttle in packaging machinery, using the equal push and pull thrust to maintain consistent cycle times in both directions.
Twin-Guided Pusher
Pushes components down an assembly line without twisting, relying on the two rods to provide ample guide length and resist rotational torque.
Dual-Station Actuation
Actuates a secondary mechanism or sensor flag from the rear rod end on a semiconductor handling fixture while the front rod drives the primary load.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X70B the Right Cylinder?
Select this 25mm bore for applications needing 188.9N of symmetric thrust at 0.5MPa. If your payload is lighter, the 20mm bore provides 117.8N, while heavier loads step up to the 32mm bore offering 301.6N. This 70mm stroke sits well within the 100mm maximum standard travel. If load holding is required during air loss, note that a plain ACQD drifts; you must add an external rod lock or pilot check valve. Choose a single-rod ACQ if you only need standard unidirectional pushing, or a guided TACQ for high lateral loads.
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 ACQD25X70B FAQ
It delivers an equal push and pull force of 188.9N at 0.5MPa and 264.5N at 0.7MPa, with a maximum capacity of 39kgf at 1.0MPa. The push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The stroke is 70mm, and the maximum standard stroke available for this 25mm bore is 100mm.
It uses fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration, which are not adjustable. For high-energy impacts, an external shock absorber is recommended. The rod ends feature male M10x1.25 threads, allowing direct coupling to your load, while the body includes grooves for mounting reed or solid-state sensors, though this model ships without a magnet.
