Airtac ACQD140 Double Rod Compact Cylinder ACQD140X150SB
The AirTAC Airtac ACQD140 Double Rod Compact Cylinder ACQD140X150SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø140mm bore and 150mm 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 ACQD140X150SB
The AirTAC ACQD140X150SB is a large-bore JIS compact cylinder featuring a double-acting design with twin piston rods extending from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding perfectly equal push and pull forces of 7294.8N at 0.5MPa and 10212.7N at 0.7MPa. The Ø32mm rods provide an extended guide length to resist torsion without needing an external non-rotating guide.
This 140mm bore variant incorporates a male M30x1.5 rod-end thread (-B) for direct mounting and a built-in piston magnet (-S) for position sensing. It uses PT3/8 ports and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The second rod end can drive a sensor flag or a secondary tool platform simultaneously.
Airtac ACQD140 Double Rod Compact Cylinder ACQD140X150SB Technical Specifications
| Model | Airtac ACQD140 Double Rod Compact Cylinder ACQD140X150SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø140 mm |
| Stroke | 150 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 ACQD140X150SB Is Used
Heavy-Duty Stamping Press
Drives a large stamping die in an automotive parts plant, utilizing the twin rods to maintain precise parallelism and prevent tool binding under high impact loads.
Symmetric Transfer Unit
Indexes heavy pallets between machining centers, using the equal push and pull forces to ensure consistent cycle times and smooth bi-directional movement.
Dual-Station Lifter
Elevates dual workpiece platforms simultaneously in a packaging line, with the second rod end driving a flag for a solid-state magnetic sensor to confirm stroke completion.
Is the Airtac ACQD140 Double Rod Compact Cylinder ACQD140X150SB the Right Cylinder?
Select this 140mm bore unit when your application requires substantial equal bidirectional thrust up to 1488kgf at 1.0MPa within a compact footprint. If you need less force, the neighboring Ø125 bore provides 5733.8N at 0.5MPa; stepping up to the Ø160 bore yields 9424.8N at 0.5MPa. Choose the ACQD140X150SB specifically for heavy symmetric transfer tasks requiring anti-rotation stability. Note that a single-rod ACQ cylinder is preferable if you only need standard unidirectional pushing and want higher forward thrust. Confirm the 150mm stroke, PT3/8 port size, and male M30x1.5 thread when 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 ACQD140X150SB FAQ
The cylinder generates equal push and pull forces of 7294.8N at 0.5MPa and 10212.7N at 0.7MPa, with a maximum holding capacity of 1488kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 140mm bore is 300mm.
It uses fixed NBR elastomer bumpers at both ends to absorb impact, meaning there is no adjustable air cushion; for high-energy cycles, you should add an external shock absorber. The -S option includes a piston magnet compatible with both reed and electronic solid-state switches mounted in the body grooves, while the -B option provides a male M30x1.5 rod thread for direct load coupling.
