Airtac ACQD Double Acting Compact Cylinder ACQD16X25SB
The AirTAC ACQD Double Acting Compact Cylinder ACQD16X25SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø16mm 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 ACQD16X25SB
The AirTAC ACQD16X25SB is a double-acting JIS compact cylinder featuring twin rods exiting both ends. Because a piston rod occupies each chamber, the annular area remains identical in both directions, yielding perfectly equal push and pull forces of 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa. This symmetry is ideal for applications requiring consistent force in both travel directions. The twin rods also significantly increase guide length and resist torsional load without needing an external anti-rotation guide.
This 16mm bore variant includes an M5x0.8 port and a male M6x1.0 threaded rod end (-B) for direct load coupling. It contains a built-in magnet (-S) compatible with reed or solid-state electronic switches via its integrated sensor grooves. Deceleration is handled by fixed TPU elastomer bumpers at both stroke ends, and the unit operates smoothly between 30-500 mm/s within a -20 to +70 C environment.

| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M4×0.7 female / M6×1.0 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 60 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 (Ø16mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 75 N | 75 N |
| 0.7 MPa | 106 N | 106 N |
| Max (@1.0 MPa) | 15 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 ACQD16X25SB Is Used
Symmetric Transfer Arms
Drives dual-sided pick-and-place arms in electronics assembly, using the second rod end to mount a counterweight or secondary actuator for balanced vertical motion.
PCB Testing Fixtures
Applies equal 75.4 N clamping and release pressure on printed circuit boards, ensuring delicate components are not crushed by uneven force during testing.
Twin-Guided Pusher
Pushes small machined parts along a conveyor in a CNC lathe, leveraging the twin rods to prevent the pusher block from twisting under friction.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD16X25SB the Right Cylinder?
When sizing this 16mm bore actuator, verify your load requires 75.4 N of equal bidirectional force at 0.5 MPa. If your application demands less force, stepping down to the 12mm bore provides 42.4 N, whereas stepping up to the 20mm bore offers 117.8 N. If you need unbalanced push force exceeding pull force, a single-rod ACQ cylinder is a better choice. For heavy lateral loads requiring extensive support, a guided TACQ model should be considered. To order, confirm the 25mm stroke, M6x1.0 male rod thread, and PT port standard.
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 ACQD16X25SB FAQ
The ACQD16X25SB delivers an equal push and pull force of 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa, with a maximum force of 15 kgf at 1.0 MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 16mm bore is 60 mm.
No, a plain ACQD does not hold its load on air loss or when a valve is centered; the rod will drift. The fixed TPU elastomer bumpers only decelerate the piston near stroke ends and do not act as a brake. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
