Airtac ACQD Double Acting Compact Cylinder ACQD50X80SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X80SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 80mm 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 ACQD50X80SB
The AirTAC ACQD50X80SB is a double-acting JIS compact cylinder featuring twin rods that exit from both ends of its riveted C-clip body. Because a piston rod occupies each internal chamber, the effective annular area remains identical in both directions. This geometry yields exactly equal push and pull forces, giving you 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa without any differential. The extended guide length resists torsional deflection, allowing you to mount a small tool platform directly without adding an external anti-rotation guide.
This 50mm bore unit includes an integrated piston magnet for position sensing alongside male M18x1.5 threaded rod ends for direct load coupling. Air enters via PT1/4 ports, and travel is halted by fixed NBR elastomer bumpers at each end. These bumpers are not adjustable air cushions; for high kinetic energy applications, slow the approach speed or install an external shock absorber. Note that a standard double-rod cylinder drifts when air pressure is lost, so add an external rod lock if fail-safe holding is required.
Airtac ACQD Double Acting Compact Cylinder ACQD50X80SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X80SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 80 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 ACQD50X80SB Is Used
Symmetric Transfer Conveyor
Drives a dual-sided pusher on a packaging line, utilizing the equal push and pull forces to move cartons smoothly in both directions without stroke imbalance.
Twin-Guided Pick & Place
Mounts a small pneumatic gripper directly to the male rod end on an electronics assembly machine, relying on the twin rods to prevent rotation during vertical pick operations.
Dual-Station Actuation
Uses the second protruding rod end to trigger a solid-state position sensor flag on a metal stamping press, while the primary end drives the forming tool.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X80SB the Right Cylinder?
Selecting this 80mm stroke model gives a 50mm bore generating 824.6N both ways. If your payload is lighter, the 40mm bore provides 527.8N, whereas the heavier 63mm bore offers 1401.5N at the same 0.5 MPa. The twin-rod build is ideal for symmetric transfer tasks, but if you need greater lateral load capacity on a single platform, a guided TACQ cylinder might fit better. Confirm your ordering essentials: this configuration includes the -S magnet for electronic or reed switches and the -B male M18x1.5 rod thread, with a maximum standard stroke limit of 100mm for this bore.
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 ACQD50X80SB FAQ
The 50mm bore provides equal push and pull forces of 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa, with a maximum load capacity of 168kgf at 1.0 MPa. Push and pull are equal because the double-rod design creates the same annular area in both chambers. The maximum standard stroke for this bore is 100mm.
The -S option adds a piston magnet compatible with both reed and electronic solid-state switches mounted in the body grooves. The -B option provides male M18x1.5 threads on the Ø20mm piston rods exiting both ends, allowing you to directly attach mounts or tooling without separate rod-end couplers.
