Airtac ACQD140 Double Rod Compact Cylinder ACQD140X30S
The AirTAC Airtac ACQD140 Double Rod Compact Cylinder ACQD140X30S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø140mm bore and 30mm 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 ACQD140X30S
The AirTAC ACQD140X30S is a double-acting JIS compact cylinder featuring a piston rod protruding from both ends. Because a rod occupies each chamber, the annular area remains identical in either direction, yielding perfectly equal push and pull forces of 7294.8N at 0.5MPa and 10212.7N at 0.7MPa. This big-bore unit handles heavy loads up to a maximum 1488kgf at 1.0MPa within a space-saving riveted body.
Its twin-rod architecture inherently resists rotation and provides an extended guide length, eliminating the need for a separate external guide in many setups. The second rod end can drive a sensor flag or a secondary load. Deceleration relies on fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. Equipped with the -S magnet, the piston works seamlessly with reed or electronic solid-state switches fitted into the body grooves.
Airtac ACQD140 Double Rod Compact Cylinder ACQD140X30S Technical Specifications
| Model | Airtac ACQD140 Double Rod Compact Cylinder ACQD140X30S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø140 mm |
| Stroke | 30 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 ACQD140X30S Is Used
Heavy-Duty Symmetric Transfer
Drives a large machining center pallet shuttle where equal push and pull forces ensure stable bidirectional indexing of heavy cast iron workpieces.
Twin-Guided Press Ejection
Ejects stamped metal parts from a press bed using the anti-rotation twin rods to prevent binding under severe off-center lateral loads.
Dual-Station Actuation
Powers a dual-station assembly fixture where the primary rod moves the tooling while the opposite rod end directly mounts a physical sensor flag.
Is the Airtac ACQD140 Double Rod Compact Cylinder ACQD140X30S the Right Cylinder?
When sizing this 140mm bore, moving down to a 125mm version drops the bidirectional force to 5733.8N at 0.5MPa, whereas stepping up to 160mm raises it to 9424.8N at 0.5MPa. Choose this specific model when your application demands massive symmetric thrust within a compact footprint. If your mechanism only requires standard unidirectional push force, a single-rod ACQ cylinder provides a simpler alternative. For loads requiring precise multi-axis guidance without torsional deflection, a guided TACQ module might fit better. Confirm your ordering essentials: 30mm stroke, PT3/8 port, M22x2.5 female rod-end thread, and the integrated magnet.
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 ACQD140X30S FAQ
This cylinder generates equal push and pull forces of 7294.8N at 0.5MPa and 10212.7N at 0.7MPa, with a maximum capacity of 1488kgf at 1.0MPa. Push equals pull because the double-rod design creates matching annular areas on both sides. The maximum standard stroke available for this 140mm big-bore variant is 300mm.
It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, meaning there is no adjustable air cushion. For high kinetic energy loads, add an external shock absorber. A plain ACQD does not hold position on air loss; the rod drifts, so you must add an external rod lock or pilot-operated check valve for fail-safe load holding.
