Airtac ACQD Double Acting Compact Cylinder ACQD12X25SB
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X25SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm bore and 25mm 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 ACQD12X25SB
The AirTAC ACQD12X25SB is a double-acting JIS compact cylinder featuring twin Ø6 mm 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 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa. This symmetry is ideal for cycles requiring consistent force both ways. The -B option provides male M5x0.8 rod-end threads for direct load coupling.
The dual rods inherently resist rotation and extend guide length, eliminating the need for a separate external anti-rotation guide in small tool platforms. The second rod end can drive a sensor flag or a secondary load. Fixed TPU elastomer bumpers at both ends manage end-of-stroke impact, while the -S magnet works with reed or electronic solid-state switches in the body grooves. Operating pressure spans 0.15-1.0 MPa with speeds of 30-500 mm/s.

| Bore size | Ø12 mm |
| Stroke | 25 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 50 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 (Ø12mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 42 N | 42 N |
| 0.7 MPa | 59 N | 59 N |
| Max (@1.0 MPa) | 9 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 ACQD12X25SB Is Used
Twin-Guided Pick-and-Place
Drives a small vacuum gripper in electronics assembly, using the opposing rod end to mount a reed sensor flag without adding an external guide rail.
Symmetric Transfer Pusher
Shifts light packaging components between two conveyor lanes with equal advance and retract force, ensuring stable part handling without rotational drift.
Dual-Station Actuation
Actuates a tiny clamping fixture on a semiconductor wafer handler, using both rod ends to operate a secondary release lever simultaneously.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X25SB the Right Cylinder?
For this 25 mm stroke, the 12 mm bore provides 42.4 N of equal bidirectional force at 0.5 MPa. Stepping up to the 16 mm bore raises that to 75.4 N if your tooling requires more push or pull, while dropping below 12 mm is not standard in this series. If your application needs a single protruding rod with higher forward thrust than return, the single-rod ACQ series is a better fit. For heavier radial loads requiring a longer bearing span, a guided TACQ cylinder should be considered. Confirm the M5x0.8 port and male M5x0.8 rod threads when specifying your mounting hardware.
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 ACQD12X25SB FAQ
The push and pull forces are equal at 42.4 N @0.5 MPa and 59.4 N @0.7 MPa, with a maximum holding capacity of 9 kgf @1.0 MPa. Because the twin rods occupy both chambers, the annular area is identical in each direction. The maximum standard stroke for this 12 mm bore is 50 mm.
The dual rods resist rotation and provide a longer guide length. It uses fixed TPU elastomer bumpers at both ends, not adjustable air cushions, so external shock absorbers may be needed for high-energy impacts. A plain ACQD does not hold its load if air pressure is lost; for fail-safe positioning, you must add an external rod lock or pilot-operated check valve.
