Airtac ACQD140 Double Rod Compact Cylinder ACQD140X40S
The AirTAC Airtac ACQD140 Double Rod Compact Cylinder ACQD140X40S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø140mm 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 ACQD140 Double Rod Compact Cylinder ACQD140X40S
The AirTAC ACQD140X40S is a double-acting, double-rod JIS compact cylinder engineered for heavy-duty applications. Because a Ø32 mm piston rod exits both ends of the body, the effective annular area remains identical in each direction. This geometry yields perfectly equal push and pull forces, delivering 7294.8 N at 0.5 MPa and 10212.7 N at 0.7 MPa in either travel direction.
Featuring a built-in magnet for solid-state or reed switches, this big-bore unit accepts up to 300 mm of standard stroke. The twin-rod layout inherently resists torsion and lengthens the guide bearing span, allowing a tool platform to be mounted directly without needing an external anti-rotation guide. Fixed NBR elastomer bumpers absorb end-of-stroke impact across the 0.15-1.0 MPa operating range, while the second rod end can drive a secondary load or sensor flag.
Airtac ACQD140 Double Rod Compact Cylinder ACQD140X40S Technical Specifications
| Model | Airtac ACQD140 Double Rod Compact Cylinder ACQD140X40S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø140 mm |
| Stroke | 40 mm |
| Acting type | Double acting, double rod |
| Port size | PT3/8 |
| Rod end thread | M22×2.5 female / M30×1.5 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 300 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 (Ø140mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 7295 N | 7295 N |
| 0.7 MPa | 10213 N | 10213 N |
| Max (@1.0 MPa) | 1488 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 ACQD140 Double Rod Compact Cylinder ACQD140X40S Is Used
Heavy-Duty Symmetric Transfer
Drives a large dual-sided transfer carriage on an automotive assembly line, utilizing the equal bidirectional force to push and pull heavy stampings without torsional deflection.
Twin-Guided Pusher Station
Actuates a heavy-duty pusher on a structural steel conveyor, where the twin rods provide the extended guide length needed to prevent binding under offset loads.
Dual-Station Actuation
Indexes a large machining fixture by driving one load from the primary rod end while mounting a sensor flag on the opposing secondary rod end for stroke confirmation.
Is the Airtac ACQD140 Double Rod Compact Cylinder ACQD140X40S the Right Cylinder?
When sizing this 140 mm bore actuator, evaluate the 0.5 MPa output of 7294.8 N against your dynamic and static load limits. If your application requires less force, the neighboring Ø100 bore provides 3524.8 N at 0.5 MPa; conversely, the Ø160 variant steps up to 9424.8 N for heavier demands. Choose this ACQD140X40S for symmetric push/pull cycles needing high resistance to rotation within a 40 mm stroke. If precise end-position holding is mandatory during air loss, recognize that the fixed bumper only decelerates near stroke end—a supplementary external rod lock or pilot check valve is required. Confirm your porting (PT3/8) and the default female M22x2.5 rod-end thread when finalizing your build.
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 ACQD140 Double Rod Compact Cylinder ACQD140X40S FAQ
The ACQD140X40S delivers an equal push and pull force of 7294.8 N at 0.5 MPa and 10212.7 N at 0.7 MPa, with a maximum capacity of 1488 kgf at 1.0 MPa. Push and pull forces are identical because the rod occupies both chambers, creating the same annular area in each direction. The maximum standard stroke available for this 140 mm bore is 300 mm.
The second rod end can be used to drive a secondary load or mount a sensor flag for position detection. It works with the built-in -S magnet, which is compatible with both reed and electronic solid-state switches. End-of-stroke energy is managed by fixed NBR elastomer bumpers; they are not adjustable, so external shock absorbers may be needed for high-speed approaches.
