Airtac ACQD140 Double Rod Compact Cylinder ACQD140X50S
The AirTAC Airtac ACQD140 Double Rod Compact Cylinder ACQD140X50S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø140mm bore and 50mm 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 ACQD140X50S
The AirTAC ACQD140X50S is a JIS-compact double-acting cylinder with twin Ø32mm rods exiting both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal 7294.8N push and pull force at 0.5MPa (10212.7N at 0.7MPa, max 1488kgf). This symmetry is ideal for opposing-stroke tooling.
The dual-rod geometry resists torsion and lengthens the guide bearing, allowing a heavy tool platform to ride directly on the cylinder without an external anti-rotation guide. The second rod end can drive a sensor flag or secondary load. It uses fixed NBR elastomer bumpers for end-stop damping, PT3/8 ports, and an M22x2.5 female rod-end thread. The built-in -S magnet supports reed or solid-state switches.
Airtac ACQD140 Double Rod Compact Cylinder ACQD140X50S Technical Specifications
| Model | Airtac ACQD140 Double Rod Compact Cylinder ACQD140X50S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø140 mm |
| Stroke | 50 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 ACQD140X50S Is Used
Twin-Guided Heavy Press
Drives a massive stamping die in an automotive parts plant, using the dual rods to prevent yaw and maintain precise parallel pressure during metal forming.
Symmetric Transfer Clamp
Actuates a centering jaw mechanism on a heavy-duty coil handling line, utilizing the identical push and pull forces to clamp and release steel billets evenly.
Dual-Station Actuation
Powers a multi-head machining fixture where the primary rod moves the cutting tool while the opposite rod end physically trips an external mechanical limit valve.
Is the Airtac ACQD140 Double Rod Compact Cylinder ACQD140X50S the Right Cylinder?
This 140mm bore provides 7294.8N of equal bidirectional force at 0.5MPa. Stepping down to a 125mm bore yields 5733.8N, while moving up to a 160mm bore provides 9424.8N. Choose this big-bore compact model when high equal-force transfer is required within a short 50mm stroke. If your layout only needs force in one direction, a single-rod ACQ saves space. For pure vertical lifting without drift on air loss, pair this cylinder with an external pilot check valve or rod lock, as the fixed bumpers only decelerate near stroke end.
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 ACQD140X50S FAQ
It generates 7294.8N at 0.5MPa and 10212.7N at 0.7MPa, with a maximum capacity of 1488kgf at 1.0MPa. Push and pull forces are exactly equal because the double-rod design creates identical annular piston areas on both sides. The standard stroke limit for this 140mm bore is 300mm.
The two Ø32mm rods resist torsion and provide extended bearing support, eliminating the need for a separate external guide in many setups. End damping is provided by fixed NBR elastomer bumpers rather than adjustable air cushions. For high kinetic energy loads, slow the approach speed or add external shock absorbers.
