Airtac ACQD Double Acting Compact Cylinder ACQD50X30B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X30B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm 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 ACQD Double Acting Compact Cylinder ACQD50X30B
The AirTAC ACQD50X30B is a double-acting JIS compact cylinder featuring a twin-rod design where a piston rod protrudes from both ends. Because a rod occupies both internal chambers, the effective annular area is identical in each direction. This means push and pull forces are perfectly equal at 824.6 N @0.5 MPa and 1154.5 N @1.0 MPa, enabling perfectly symmetric cycles without force imbalance.
The dual rods provide extended guiding length and high resistance to rotation, allowing it to carry a tool platform directly without needing an external anti-rotation guide. This specific variant includes a male-thread rod end (M18x1.5) for direct load coupling and a PT1/4 port. Deceleration is handled by fixed NBR elastomer bumpers at both ends, rather than adjustable air cushions. Note that this model ships without a sensor magnet, though the body retains switch grooves for future use.
Airtac ACQD Double Acting Compact Cylinder ACQD50X30B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X30B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 30 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 ACQD50X30B Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer arm in packaging machinery, using the equal push and pull forces to move products smoothly in both directions without torque imbalance.
Twin-Guided Stamping Platform
Carries a small stamping or marking head on a second rod end in electronics manufacturing, leveraging the anti-rotation properties to maintain precise angular alignment.
Dual-Station Actuation
Powers a dual-station clamping fixture on an automotive parts assembly line, using the protruding secondary rod to mount a mechanical flag or secondary load.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X30B the Right Cylinder?
When sizing this 50mm bore, consider the neighbouring capacities: a 40mm bore yields 527.8 N @0.5 MPa, while stepping up to a 63mm bore provides 1401.5 N @0.5 MPa. If your application requires push force to exceed pull force, a single-rod ACQ cylinder is a better choice. For applications with heavy lateral loads needing external guide rails, a guided TACQ cylinder offers superior support. To order, confirm the 50mm bore, 30mm stroke, male M18x1.5 rod thread, and PT1/4 porting.
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 ACQD50X30B FAQ
The push and pull forces are equal due to the double-rod annular area: 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa, with a maximum of 168 kgf at 1.0 MPa. The standard stroke limit for this 50mm bore is 100mm, and this specific model has a 30mm stroke.
It uses fixed NBR elastomer bumpers at both ends for impact absorption, not adjustable air cushions. Because it is a standard compact cylinder, it does not hold position if air pressure is lost; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
