Airtac ACQD Double Acting Compact Cylinder ACQD50X300B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X300B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 300mm 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 ACQD50X300B
The AirTAC ACQD50X300B is a double-acting JIS compact cylinder featuring a 300mm stroke and a piston rod extending from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding perfectly equal push and pull forces of 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa. The twin rods inherently resist rotation and provide an extended guide length, allowing you to carry a tool platform without adding an external guide. This 50mm bore variant features a male M18x1.5 rod-end thread for direct load coupling and a PT1/4 port.
This unit is a long-stroke, made-to-order variant exceeding the 100mm standard maximum for its bore. It relies on fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The body includes magnetic-switch grooves, but this specific configuration ships without a magnet. Note that a standard compact cylinder does not hold position upon air loss; if fail-safe load holding is required, an external rod lock or pilot check valve must be installed.
Airtac ACQD Double Acting Compact Cylinder ACQD50X300B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X300B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 300 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 ACQD50X300B Is Used
Symmetric Transfer Pusher
Drives a dual-sided pusher on a packaging conveyor where the 824.6N equal force ensures consistent advancement and retraction across the 300mm travel.
Twin-Guided Actuation
Actuates a secondary mechanism or sensor flag via the second rod end on an automated assembly machine without needing a separate anti-rotation block.
Dual-Station Indexing
Shifts a tooling carriage between two stations on a CNC loading station, utilizing the twin rods to maintain platform stability over the extended 300mm span.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X300B the Right Cylinder?
Selecting this 50mm bore double-rod cylinder provides 824.6N of equal bidirectional force at 0.5 MPa. If your application requires less force, the neighboring 40mm bore delivers 527.8N, while stepping up to the 63mm bore provides 1401.5N. This 300mm stroke is a nonstandard long-stroke configuration; for shorter travels under 100mm, the standard ACQD50 offers quicker availability. If your mechanism already features an external linear guide and does not require anti-rotation, a single-rod ACQ50 may suffice. When ordering, confirm the 50mm bore, 300mm stroke, and the -B male M18x1.5 rod thread requirement.
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 ACQD50X300B FAQ
The ACQD50X300B provides equal push and pull forces of 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa, with a maximum force of 168kgf at 1.0 MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The 300mm stroke is a nonstandard long-stroke variant, exceeding the 100mm standard maximum for this 50mm bore.
This model uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration; it does not have adjustable air cushions. A standard ACQ-type cylinder does not hold its load if air pressure is lost, so for fail-safe positioning, you must install an external rod lock or pilot-operated check valve.
