Airtac ACQD Double Acting Compact Cylinder ACQD50X75SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X75SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 75mm 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 ACQD50X75SB
The AirTAC ACQD50X75SB is a double-acting JIS compact cylinder where a Ø20mm piston rod protrudes from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding perfectly symmetric thrust of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. The twin-rod architecture inherently resists rotation and extends guiding depth, eliminating the need for an external anti-rotation guide while allowing a second load or sensor flag to mount on the opposite end.
This 50mm bore unit features a 75mm stroke and integrated NBR elastomer bumpers at both ends to absorb impact energy near stroke limits. The -S magnet enables tracking via reed or solid-state electronic switches, while the -B male M18x1.5 rod-end thread couples directly to your tooling. Operating pressure spans 0.15-1.0MPa, with a PT1/4 port ensuring reliable pneumatic supply.
Airtac ACQD Double Acting Compact Cylinder ACQD50X75SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X75SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 75 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 ACQD50X75SB Is Used
Symmetric Transfer Unit
Drives a dual-sided packaging pusher where matching push and pull thrust of 824.6N ensures stable product transfer without momentum shifts.
Twin-Guided Stripper
Resists rotational torque during stamping eject operations, using the second rod end to mount a mechanical stop or sensor flag.
Dual-Station Actuation
Powers a 50mm bore assembly station platform, simultaneously indexing two tooling plates via both M18x1.5 male rod ends.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X75SB the Right Cylinder?
Select this 50mm bore if your application requires 824.6N of bi-directional force at 0.5MPa. Stepping down to a 40mm bore yields 527.8N, whereas moving up to a 63mm bore provides 1401.5N. A standard single-rod ACQ is preferable when equal push/pull cycles are unnecessary, or a guided TACQ excels if heavy lateral loads exceed twin-rod capacity. This configuration includes the -S magnet for switch readiness and the -B male M18x1.5 thread for direct mounting.
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 ACQD50X75SB FAQ
It delivers 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 double-rod design creates equal annular areas in both chambers. The stroke is 75mm, and the maximum standard stroke for this 50mm bore is 100mm.
No, a plain ACQD does not hold position upon air loss; the rod drifts and the fixed NBR bumper only decelerates near stroke end. For fail-safe load holding, an external rod lock or pilot-operated check valve is required. The twin rods prevent rotation, and the -S magnet works with reed or electronic switches for position sensing.
