Airtac ACQD Double Acting Compact Cylinder ACQD63X50S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X50S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm 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 ACQD63X50S
The AirTAC ACQD63X50S is a double-acting JIS compact cylinder featuring twin rods extending from both body ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. The integrated piston magnet (-S) pairs with reed or solid-state switches via built-in grooves for position sensing.
Twin rods inherently resist rotation and lengthen the guide span, allowing a tool platform to be carried directly without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. Deceleration relies on fixed NBR elastomer bumpers at each end rather than adjustable air cushions, and the PT1/4 porting handles standard pneumatic supply.
Airtac ACQD Double Acting Compact Cylinder ACQD63X50S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X50S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 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 (Ø63mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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 ACQD63X50S Is Used
Symmetric Transfer Unit
Drives a dual-sided parts shuttle on an assembly line where matching push and pull forces prevent uneven wear during rapid reversals.
Twin-Guided Tool Platform
Carries a small machining head directly on the extended rods, leveraging the extended guide length to resist torsional twist without external rails.
Dual-Station Actuation
Uses the second protruding rod end to trigger an external mechanical flag on a packaging machine while the primary end performs the main work stroke.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X50S the Right Cylinder?
Providing 1401.5 N of symmetric force both ways at 0.5 MPa, this 63mm bore suits loads needing stability without external guides. For lighter duty at 0.5 MPa, a 50mm bore yields 824.6 N, while a heavier 80mm bore provides 2267.8 N. If your application only needs unidirectional push force, a single-rod ACQ offers a more compact footprint, and a guided TACQ fits when external lateral loads are high. Verify your load requires 50mm of travel, select the -S magnet for sensing, and confirm the default female M10x1.5 rod-end thread matches your tooling.
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 ACQD63X50S FAQ
It delivers an equal push and pull force of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, with a maximum of 286 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The maximum standard stroke for this 63mm bore is 100mm, and operating pressure is 0.15-1.0 MPa.
Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions. The built-in -S magnet works with reed or solid-state switches for position sensing. Note that a plain ACQD does not hold its load if air pressure is lost; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
