Airtac ACQD Double Acting Compact Cylinder ACQD63X50H
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X50H 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 ACQD63X50H
The ACQD63X50H is a double-acting JIS compact cylinder featuring twin Ø20 mm rods extending from both body ends. Because a rod occupies each chamber, the 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. This symmetry ensures perfectly balanced cycle dynamics without the force disparity found in single-rod units.
The dual rods provide inherent anti-rotation support and an extended guide length, eliminating the need for a separate external guide in many setups. Built with a compact C-clip and riveted body, it includes fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. The body features magnetic-switch grooves for adding reed or solid-state sensors, though this specific unit ships without a magnet. It uses a PT1/4 port and a female M10x1.5 rod-end thread.
Airtac ACQD Double Acting Compact Cylinder ACQD63X50H Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X50H |
|---|---|
| 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 ACQD63X50H Is Used
Symmetric Transfer Unit
Drives a dual-sided clamping mechanism in CNC machining centers where equal push and pull forces prevent workpiece distortion during part transfer.
Twin-Guided Pusher
Transfers heavy metal billets along a conveyor in a steel mill, using the inherent twin-rod anti-rotation to maintain pushing platform alignment.
Dual-Station Actuation
Powers a secondary tooling platform on an automated packaging line, using the opposite rod end to trigger a solid-state flag sensor.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X50H the Right Cylinder?
At 0.5 MPa, this 63 mm bore generates 1401.5 N of force in both directions. If your application requires less force, the next smaller 50 mm bore provides 824.6 N. For heavier loads, the 80 mm bore offers 2267.8 N. If your mechanism already uses an external linear guide and only needs unidirectional thrust, a single-rod ACQ cylinder might be a simpler choice. For ordering, confirm the 50 mm stroke, the default female M10x1.5 rod thread, and the PT1/4 pneumatic port.
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 ACQD63X50H 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 holding capability of 286 kgf at 1.0 MPa. Push and pull forces are identical because the double-rod design creates the same annular piston area in both chambers. The maximum standard stroke available for this 63 mm bore is 100 mm.
No, a plain ACQD cylinder drifts when air is lost or the valve is centered. The fixed NBR elastomer bumpers only decelerate the piston near the stroke ends and do not act as a brake. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
