Airtac ACQD Double Acting Compact Cylinder ACQD50X40
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X40 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm 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 ACQD Double Acting Compact Cylinder ACQD50X40
The AirTAC ACQD50X40 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 both directions, generating equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This symmetry is ideal for applications requiring consistent bi-directional thrust without force drop on the retract stroke.
Twin rods provide extended guiding length and high torsional resistance, allowing you to carry a small tool platform directly without adding a separate external anti-rotation guide. The body incorporates fixed NBR elastomer bumpers at each end to soften end-of-stroke impacts, and includes magnetic-switch grooves, though this specific configuration ships without the -S magnet. With a 50mm bore, 40mm stroke, PT1/4 port, and a 20mm diameter rod with an M10x1.5 female thread, it offers robust performance within a minimal footprint.
Airtac ACQD Double Acting Compact Cylinder ACQD50X40 Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 40 mm |
| Acting type | Double acting, double rod |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 100 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 (Ø50mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 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 ACQD Double Acting Compact Cylinder ACQD50X40 Is Used
Symmetric Transfer Shuttle
Drives a dual-sided pick-and-place shuttle in packaging lines where identical push and pull thrust ensures stable product handoff without momentum shifts.
Twin-Guided Pusher Station
Pushes parts along a conveyor using a directly mounted tool plate, relying on the two rods to prevent torsional deflection under offset loads.
Dual-Station Actuation
Actuates two separate clamps or stations sequentially in CNC machining centers, utilizing the second protruding rod end to drive a secondary mechanism.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X40 the Right Cylinder?
Selecting this 50mm bore yields 824.6N of thrust both ways at 0.5MPa. If your payload is lighter, stepping down to a 40mm bore provides 527.8N, whereas moving up to a 63mm bore offers 1401.5N for heavier demands. This twin-rod design is optimal when you need built-in rotational resistance; if your mechanism only requires standard single-direction actuation, a single-rod ACQ cylinder is sufficient. When ordering, confirm the 40mm stroke, the default female M10x1.5 rod-end thread, and the PT1/4 port size.
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 ACQD Double Acting Compact Cylinder ACQD50X40 FAQ
It delivers equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum capacity of 168kgf at 1.0MPa. Push equals pull because the twin rods create identical annular areas on both sides. The maximum standard stroke available for this 50mm bore is 100mm.
The dual-rod construction inherently resists rotation and provides a longer guide length, eliminating the need for an external anti-rotation guide. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. Note that this model lacks the -S magnet, so while sensor grooves exist, no magnetic field is generated for switches.
