Airtac ACQD Double Acting Compact Cylinder ACQD16X40S
The AirTAC ACQD Double Acting Compact Cylinder ACQD16X40S 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 ACQD16X40S
The AirTAC ACQD16X40S is a double-acting JIS compact cylinder featuring twin Ø8mm piston rods exiting both ends. Because a rod occupies each working chamber, the annular area is identical in both directions, yielding perfectly equal push and pull forces of 75.4N at 0.5MPa and 105.6N at 0.7MPa. This symmetric force profile is ideal for applications requiring consistent bidirectional cycling.
The dual-rod architecture inherently resists rotation and extends the guide length, allowing you to mount a small tool platform directly without needing a separate external anti-rotation guide. A fixed TPU elastomer bumper inside the compact riveted body absorbs impact at stroke ends, while the included -S magnet enables tracking via reed or solid-state electronic switches. The unit uses an M5x0.8 port and default female M4x0.7 rod-end threads.
Airtac ACQD Double Acting Compact Cylinder ACQD16X40S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD16X40S |
|---|---|
| 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 ACQD16X40S Is Used
Symmetric Transfer Shuttle
Drives a pick-and-place shuttle on an electronics assembly line, utilizing the equal push and pull forces to move components smoothly in both directions without force imbalance.
Twin-Guided Parts Pusher
Ejects machined plastic parts from a molding cell, relying on the dual rods to prevent yaw and maintain precise alignment of the ejection plate.
Dual-Station Actuation
Powers a compact testing fixture where one rod end drives the primary test probe while the opposite end mounts a sensor flag for position verification.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD16X40S the Right Cylinder?
Choosing this 16mm bore with a 40mm stroke provides 75.4N of equal bidirectional force at 0.5MPa. If your payload is lighter, stepping down to the 12mm bore yields 42.4N, whereas moving up to the 20mm bore provides 117.8N for heavier tooling. If your mechanism only needs unidirectional thrust, a single-rod ACQ cylinder offers a more compact footprint. Remember to specify the -S magnet for sensing and confirm your M4x0.7 female rod thread. Note that a plain ACQD will drift if air pressure is lost; add an external rod lock or pilot check valve for fail-safe load holding.
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 ACQD16X40S FAQ
The ACQD16X40S provides equal push and pull forces of 75.4N at 0.5MPa and 105.6N at 0.7MPa, with a maximum holding force of 15kgf at 1.0MPa. Push and pull are equal because the twin rods create matching annular areas in both chambers. The maximum standard stroke available for the 16mm bore is 60mm.
The twin-rod design resists torsional rotation and lengthens the guide support, eliminating the need for an external guide in many setups. Impact at the ends of travel is controlled by fixed TPU elastomer bumpers rather than adjustable air cushions. For high-speed or high-energy cycles, you should slow the approach or add an external shock absorber.
