Airtac ACQD Double Acting Compact Cylinder ACQD50X50B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X50B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 50mm 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 ACQD50X50B
The AirTAC ACQD50X50B is a double-acting JIS compact cylinder featuring twin Ø20mm rods exiting both ends. Because a rod occupies each chamber, the annular piston area is identical in both directions, yielding exactly 824.6N at 0.5MPa and 1154.5N at 0.7MPa of thrust and pull. This equal-force design enables perfectly symmetric cycles without force mismatch.
Built with a fixed NBR elastomer bumper at each end, it absorbs end-of-stroke impact without adjustable air cushions. The extended guide length from the dual rods resists torsion, letting you mount a tool platform directly without an external guide. This B-option variant includes male M18x1.5 rod-end threads for direct load coupling, and the body retains sensor grooves for adding reed or solid-state switches later.
Airtac ACQD Double Acting Compact Cylinder ACQD50X50B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X50B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 50 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 ACQD50X50B Is Used
Symmetric Transfer Pusher
Drives a dual-sided conveyor pusher in packaging lines, using the equal push and pull forces to shift cartons cleanly in both directions without guide binding.
Twin-Guided Cutting Station
Powers a film or web slitter where the twin rods prevent blade rotation during penetration, ensuring a straight cut without a separate external guide.
Dual-Station Actuation
Actuates two adjacent test fixtures simultaneously in electronics manufacturing, using the second protruding rod end to drive a secondary contact block.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X50B the Right Cylinder?
For 50mm bore sizing, the ACQD50X50B delivers 824.6N both ways at 0.5MPa. If you need less force, the ACQD40X50B provides 527.8N; for heavier drives, the ACQD63X50B outputs 1401.5N. Choose this double-rod model when your mechanism needs anti-rotation or a second rod end for a sensor flag. If rotation is not a concern, a single-rod ACQ50X50B is more compact. If your load drifts on air loss, add an external rod lock or pilot check valve, as the fixed bumper only decelerates near stroke end. Confirm PT1/4 ports and the M18x1.5 male thread 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 ACQD50X50B 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 equals pull because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 50mm bore is 100mm.
The twin rods resist torsion and provide a longer guide length. It uses fixed NBR elastomer bumpers at both ends for impact absorption, not adjustable air cushions. This B-option model has male M18x1.5 rod threads for direct mounting; while it ships without a magnet, the body features grooves ready for reed or solid-state switches.
