Airtac ACQD Double Acting Compact Cylinder ACQD50X100SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X100SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 100mm 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 ACQD50X100SB
The AirTAC ACQD50X100SB is a double-acting JIS compact cylinder where a rod protrudes from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This symmetry is ideal for cycles requiring consistent force both ways.
The twin rods prevent rotation and extend the guiding length, allowing you to mount a tool platform without needing an external guide. This 50mm bore variant includes a male M18x1.5 rod-end thread for direct coupling, a built-in magnet for reed or solid-state switches, and fixed NBR bumpers at both ends. It operates at 0.15-1.0MPa with a speed range of 30-500mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD50X100SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X100SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 100 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 ACQD50X100SB Is Used
Symmetric Transfer Unit
Moves parts between stations with identical push and pull force, ensuring stable transit without momentum shifts.
Twin-Guided Pusher
Pushes products on a conveyor using the dual rods to resist torsional loads and maintain alignment without an external guide.
Dual-Station Actuation
Drives a secondary mechanism or sensor flag from the rear rod end while the front rod executes the primary work task.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X100SB the Right Cylinder?
Selecting this 50mm bore with a 100mm stroke provides a maximum standard stroke capacity of 824.6N at 0.5MPa. If your application needs less force, step down to the 40mm bore (527.8N), or step up to the 63mm bore (1401.5N) for heavier loads. If your mechanism already features an external linear guide and only needs a basic actuator, a single-rod ACQ cylinder is a simpler choice. Confirm the PT1/4 port, male M18x1.5 rod thread, and magnet options when ordering.
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 ACQD50X100SB FAQ
It delivers equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum load of 168kgf at 1.0MPa. Push and pull are equal because the rods occupy both chambers, creating identical annular areas. The maximum standard stroke is 100mm.
No, a plain ACQD does not hold position on air loss; the rod drifts. The fixed NBR bumpers only decelerate the piston near stroke ends. For fail-safe holding, install an external rod lock or pilot-operated check valve.
