Airtac ACQD140 Double Rod Compact Cylinder ACQD140X100S
The AirTAC Airtac ACQD140 Double Rod Compact Cylinder ACQD140X100S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø140mm bore and 100mm 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 ACQD140X100S
The AirTAC ACQD140X100S is a large-bore JIS compact pneumatic cylinder featuring a dual-rod design where a piston extends from both ends. Because both chambers share the same annular area, it delivers identical extending and retracting forces of 7294.8N at 0.5MPa and 10212.7N at 0.7MPa. This symmetry is ideal for operations requiring perfectly balanced push and pull cycles.
The twin rods provide extended guide length and high torsional resistance, allowing you to mount a tooling platform directly without adding an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. It uses a fixed NBR elastomer bumper for end-of-stroke deceleration rather than an adjustable cushion, and the included -S magnet works with reed or solid-state switches in the body grooves.
Airtac ACQD140 Double Rod Compact Cylinder ACQD140X100S Technical Specifications
| Model | Airtac ACQD140 Double Rod Compact Cylinder ACQD140X100S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø140 mm |
| Stroke | 100 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 ACQD140X100S Is Used
Heavy-Duty Twin-Guided Pusher
Drives a large stamping or pressing head in automotive assembly lines, utilizing the dual rods to maintain parallelism and prevent torsional deflection under high side loads.
Symmetric Transfer Mechanism
Powers a dual-station transfer arm in packaging machinery, where the equal annular push and pull forces ensure consistent cycling speeds in both directions.
Dual-Load Actuation Station
Actuates a primary clamp on the main rod end while using the opposite protruding rod to trigger a solid-state sensor flag for position confirmation in CNC machining.
Is the Airtac ACQD140 Double Rod Compact Cylinder ACQD140X100S the Right Cylinder?
For 100mm travel at 0.5MPa, the neighboring Ø125 bore yields 5733.8N, while the Ø160 option provides 9424.8N, making this Ø140 unit a strong middle ground for heavy tooling. If your application only requires one-sided actuation and you want higher forward thrust, a single-rod ACQ cylinder is preferable. If you need fail-safe load holding when air pressure drops, pair this cylinder with an external rod lock or pilot-operated check valve, as the fixed bumper alone will not prevent drift. Confirm the PT3/8 port and M22x2.5 female rod-end thread during 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 ACQD140 Double Rod Compact Cylinder ACQD140X100S FAQ
It delivers an equal push and pull force of 7294.8N at 0.5MPa and 10212.7N at 0.7MPa, with a maximum holding force of 1488kgf at 1.0MPa. The push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The standard stroke maximum for this 140mm bore is 300mm, and operating pressure ranges from 0.15-1.0MPa.
The two parallel rods exiting the body resist torsion and provide a longer bearing length, which stabilizes attached tooling without needing a separate external guide. For end-of-stroke deceleration, it relies on fixed NBR elastomer bumpers rather than adjustable air cushions; for high-speed or high-energy loads, you should add an external shock absorber or slow the approach speed.
