Airtac ACQD Double Acting Compact Cylinder ACQD16X40B
The AirTAC ACQD Double Acting Compact Cylinder ACQD16X40B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø16mm bore and 40mm 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 ACQD16X40B
The AirTAC ACQD16X40B is a double-acting JIS compact cylinder featuring twin 8mm rods that exit both ends of the riveted body. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 75.4N at 0.5MPa and 105.6N at 0.7MPa. This symmetric output is ideal for precise transfer tasks.
The dual rods resist rotation and extend guide length without needing an external guide rail. This B-option variant includes male M6x1.0 rod-end threads for direct load coupling. It uses fixed TPU bumpers for end-of-stroke deceleration, and the body retains sensor grooves for adding external switches, though this specific unit ships without a magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD16X40B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD16X40B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø16 mm |
| Stroke | 40 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 ACQD16X40B Is Used
Symmetric Transfer Shuttle
Drives a dual-sided pick-and-place shuttle in electronics assembly, using the equal push/pull force to maintain stable horizontal positioning without rotational drift.
Twin-Guided Component Pusher
Pushes small PCB fixtures into a test socket on an SMT line, relying on the two 8mm rods to prevent binding and maintain alignment over the 40mm travel.
Dual-Station Actuation
Uses both protruding rod ends to operate a primary clamp and a secondary sensor flag simultaneously on a small packaging machine, saving space.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD16X40B the Right Cylinder?
Providing 75.4N at 0.5MPa, this 16mm bore sits between the 12mm (42.4N) and 20mm (117.8N) sizes; choose the 20mm if your payload exceeds 75N, or the 12mm for lighter 40N duties. Select this twin-rod ACQD over a single-rod ACQ when symmetric push/pull cycles or anti-rotation are required. If you need precise guided lifting beyond what the dual rods offer, a guided TACQ slide is preferable. Confirm your port size (M5x0.8) and the 40mm stroke requirement before ordering.
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 ACQD16X40B FAQ
It generates 75.4N at 0.5MPa and 105.6N at 0.7MPa, with a maximum allowable force of 15kgf at 1.0MPa. Because it is a double-rod design with equal annular areas, push and pull forces are identical. The maximum standard stroke for a 16mm bore is 60mm.
It uses fixed TPU bumpers at both ends for impact absorption, not adjustable air cushions. A plain ACQD does not hold its load when air is lost; if fail-safe holding is required, you must add an external rod lock or pilot-operated check valve.
