Airtac ACQD Double Acting Compact Cylinder ACQD16X25B
The AirTAC ACQD Double Acting Compact Cylinder ACQD16X25B 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 ACQD16X25B
The AirTAC ACQD16X25B is a double-acting JIS compact cylinder featuring twin rods that exit both ends of its C-clip riveted body. Because a rod occupies each chamber, the annular area remains identical in both directions, yielding an equal push and pull force of 75.4 N at 0.5 MPa. This symmetric thrust is ideal for balanced, reversing cycles.
The dual rods inherently resist rotation and extend the guide length, allowing you to mount a small tool platform directly without needing an external anti-rotation guide. This B-option unit features an M6x1.0 male thread on the rod end for direct load coupling, an M5x0.8 PT port, and a fixed TPU elastomer bumper at each end. Note that this specific configuration ships without a magnet, though the body retains sensor grooves for external reed or solid-state switches.
Airtac ACQD Double Acting Compact Cylinder ACQD16X25B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD16X25B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø16 mm |
| Stroke | 25 mm |
| 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 ACQD16X25B Is Used
Twin-Guided Pusher
Drives a small machining pusher station where the dual rods prevent deflection and maintain precise alignment during clamping.
Symmetric Transfer
Handles balanced pick-and-place transfer in electronics assembly, using the equal push/pull force to maintain consistent cycle timing.
Dual-Station Actuation
Powers a dual-station actuation mechanism on packaging machinery, using the second rod end to drive a secondary flag or load.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD16X25B the Right Cylinder?
At 0.5 MPa, this 16mm bore generates 75.4 N of force both ways; stepping down to a 12mm bore yields 42.4 N, while moving up to a 20mm bore provides 117.8 N. If your application requires holding the load on air loss, a plain ACQD will drift when pressure drops, so you must add an external rod lock or pilot-operated check valve. Choose this 25mm stroke variant when compact 25mm travel is needed; the maximum standard stroke for this bore is 60mm. Ensure your ordering code specifies the -B male thread if direct mounting is required.
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 ACQD16X25B FAQ
The ACQD16X25B provides 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 twin rods create the same annular area in both chambers. The maximum standard stroke available for this 16mm bore is 60mm.
No, a plain ACQD does not hold its position upon air loss; the rod will drift. The fixed TPU elastomer bumper only decelerates the piston near the stroke ends and is not an adjustable air cushion or brake. For fail-safe load holding, you must install an external rod lock or pilot-operated check valve.
