Airtac ACQD Double Acting Compact Cylinder ACQD63X20B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X20B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 20mm 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 ACQD63X20B
The AirTAC ACQD63X20B is a double-acting JIS compact cylinder featuring twin rods that exit both ends of the body. Because a piston rod occupies each chamber, the effective annular area remains identical in both directions. This yields perfectly equal push and pull forces of 1401.5N at 0.5 MPa and 1962.2N at 0.7 MPa, with a maximum capacity of 286 kgf at 1.0 MPa.
The dual-rod architecture inherently resists torsion and extends the guide bearing length, eliminating the need for an external anti-rotation guide in many applications. This specific unit includes a male M18x1.5 rod-end thread on both sides for direct load coupling. It relies on fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions, and the body features integrated grooves for mounting reed or solid-state sensors.
Airtac ACQD Double Acting Compact Cylinder ACQD63X20B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X20B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 20 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 ACQD63X20B Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place head in electronics assembly, using the equal push and pull forces to maintain stable acceleration and deceleration profiles.
Twin-Guided Pusher
Indexes PCB panels on a conveyor line where the twin rods prevent platform twisting without requiring a bulky external linear guide rail.
Dual-Station Actuation
Operates a secondary clamping mechanism via the rear rod end on a CNC machining fixture while the front rod drives the primary workpiece stop.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X20B the Right Cylinder?
When sizing this 63mm bore, consider the neighboring options: the 50mm bore provides 824.6N at 0.5 MPa, while the 80mm bore offers 2267.8N at 0.5 MPa. The ACQD63X20B is optimal when your cycle requires 1401.5N of symmetric force across a 20mm stroke. If your mechanism only needs single-sided actuation, the standard single-rod ACQ series provides greater forward thrust. For applications demanding precise non-rotating guidance over longer strokes, a guided TACQ cylinder might be a better fit. Ensure your setup specifies PT1/4 ports and the male M18x1.5 rod threads for proper integration.
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 ACQD63X20B FAQ
It generates 1401.5N at 0.5 MPa and 1962.2N at 0.7 MPa, with a maximum capacity of 286 kgf at 1.0 MPa. Push and pull forces are identical because the double-rod design creates equal annular areas on both sides. The maximum standard stroke available for this 63mm bore is 100mm.
The twin rods resist rotation and provide extended guiding length. End-of-stroke deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. A plain ACQD does not hold its position when air pressure is lost; for fail-safe load holding, you must install an external rod lock or pilot-operated check valve.
