Airtac ACQD Double Acting Compact Cylinder ACQD50X40SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X40SB 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 ACQD50X40SB
The AirTAC ACQD50X40SB is a double-acting JIS compact cylinder featuring a 50mm bore and 40mm stroke. Because twin rods exit both ends, the annular piston area remains identical in either direction, generating an equal 824.6N of thrust and pull at 0.5MPa. This symmetric force profile is ideal for balanced cycling, while the parallel rods inherently resist torsion without needing an external guide.
This specific configuration includes a piston magnet for electronic or reed switch sensing, along with male M18x1.5 rod-end threads that couple directly to your tooling. The body uses a space-saving riveted design with integrated NBR elastomer bumpers fixed at both ends to soften end-of-stroke impacts. Operating pressure ranges from 0.15-1.0MPa, and the PT1/4 port ensures adequate airflow for its 30-500mm/s speed range.
Airtac ACQD Double Acting Compact Cylinder ACQD50X40SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X40SB |
|---|---|
| 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 ACQD50X40SB Is Used
Symmetric Transfer Shuttle
Drives a packaging line shuttle where equal push and pull forces prevent drift during high-speed part transfer between stations.
Twin-Guided Pick & Place
Lifts electronic components on a dual-rail head, relying on the twin rods to resist torsion and maintain precise vertical alignment.
Dual-Station Actuator
Powers a small clamping platform on an assembly machine, using the second protruding rod end to mount a sensor flag for position confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X40SB the Right Cylinder?
Selecting this 50mm bore provides 824.6N of equal bidirectional force at 0.5MPa. If your application requires less thrust, stepping down to a 40mm bore yields 527.8N; conversely, a 63mm bore offers 1401.5N for heavier payloads. Choose this ACQD variant when your mechanism demands anti-rotation stability or a secondary mounting point, whereas a standard single-rod ACQ is sufficient for basic linear pushes. Confirm your ordering essentials: this SB option specifies the male M18x1.5 thread and built-in magnet, with a maximum standard stroke limit of 100mm for this body 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 ACQD50X40SB FAQ
This double-acting cylinder outputs an equal push and pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum capacity of 168kgf at 1.0MPa. Push and pull forces are identical because the twin rods occupy both chambers, creating equal annular areas. The maximum standard stroke available for this 50mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends to decelerate the piston, meaning there is no adjustable air cushion. For high-energy impacts, you should add an external shock absorber. Additionally, a plain ACQ-type cylinder does not hold its load if air pressure is lost; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
