Airtac ACQD Double Acting Compact Cylinder ACQD12X50B
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X50B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm 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 ACQD Double Acting Compact Cylinder ACQD12X50B
The AirTAC ACQD12X50B is a double-acting JIS compact cylinder featuring a 12mm bore and 50mm stroke, with twin Ø6mm rods exiting both ends. Because a rod occupies each chamber, the annular area is identical in both directions, generating perfectly equal push and pull forces of 42.4N at 0.5 MPa and 59.4N at 0.7 MPa. This symmetric thrust is ideal for applications requiring consistent bi-directional cycling.
The dual-rod layout inherently resists rotation and extends the guiding length, allowing a small tool platform to be carried directly without needing a separate external guide. This B-option variant features M5x0.8 male rod-end threads for direct load coupling, while the body incorporates fixed TPU elastomer bumpers at each end for end-of-stroke deceleration. Although this specific unit ships without a magnet, the body retains magnetic-switch grooves for future sensing upgrades.
Airtac ACQD Double Acting Compact Cylinder ACQD12X50B Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 50 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 50 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 (Ø12mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 42 N | 42 N |
| 0.7 MPa | 59 N | 59 N |
| Max (@1.0 MPa) | 9 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 ACQD12X50B Is Used
Symmetric Transfer Pusher
Drives a small parts shuttle back and forth across a conveyor in packaging machinery, utilizing the equal push and pull forces to maintain consistent cycle times.
Twin-Guided Pick & Place
Mounts directly to a lightweight tooling plate in electronics assembly, leveraging the anti-rotation properties of the dual rods to prevent deflection during vertical placement.
Dual-Station Actuation
Operates a secondary sensor flag or small latch on the opposite rod end in a semiconductor tester, allowing one cylinder to trigger two separate mechanical events.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X50B the Right Cylinder?
Selecting this 12mm bore provides 42.4N of thrust at 0.5 MPa; if your application requires less force, stepping down is not an option as this is the smallest available bore. Conversely, moving up to a 16mm bore increases thrust to 75.4N at 0.5 MPa if your payload demands more power. This model is specified with a 50mm stroke, which is the maximum standard stroke for the 12mm bore. If your mechanism only needs one-sided actuation and unequal force is acceptable, a single-rod ACQ cylinder offers a more compact footprint. For heavier radial loads requiring extended support, a guided TACQ series might be a better fit. Confirm your ordering essentials: this configuration includes the B-option male M5x0.8 rod threads and standard PT M5x0.8 ports.
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 ACQD12X50B FAQ
It delivers an equal push and pull force of 42.4N at 0.5 MPa and 59.4N at 0.7 MPa, with a maximum capacity of 9 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The 50mm stroke is the maximum standard stroke available for the 12mm bore.
It uses fixed TPU elastomer bumpers at both ends to decelerate the piston, meaning it does not have adjustable air cushions. If air pressure is lost, the cylinder will not hold its load and the rod will drift; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
