Airtac ACQD Double Acting Compact Cylinder ACQD63X70SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X70SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 70mm 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 ACQD63X70SB
The AirTAC ACQD63X70SB is a double-acting JIS compact cylinder featuring a piston rod exiting both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding perfectly equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This symmetry is ideal for cycles requiring consistent bi-directional thrust, reaching a maximum of 286kgf at 1.0MPa.
Twin rods resist rotation and provide an extended guide length, allowing you to carry a small tool platform without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. This 63mm bore unit includes a male M18x1.5 rod-end thread for direct coupling, fixed NBR elastomer bumpers at both ends, and a built-in magnet compatible with reed or solid-state switches.
Airtac ACQD Double Acting Compact Cylinder ACQD63X70SB Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 70 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 ACQD63X70SB Is Used
Symmetric Transfer Pusher
Drives a dual-sided parts pusher in packaging machinery where matching advance and retract forces prevent jarring during rapid cycling.
Twin-Guided Tooling Platform
Carries a small machining fixture on a CNC loader, using the extended guide length to resist torsional deflection without external rails.
Dual-Station Actuation
Powers a diverter gate on a conveyor line, using the second rod end to mechanically trigger a positional flag for control logic.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X70SB the Right Cylinder?
Selecting this 63mm bore involves sizing against adjacent options. The 50mm bore provides 824.6N at 0.5MPa, while the 80mm bore yields 2267.8N at 0.5MPa; this model delivers 1401.5N at 0.5MPa, striking a balance for medium-duty transfer. If your application only requires unidirectional thrust and standard guiding, a single-rod ACQ cylinder might suffice. However, if you need strict anti-rotation and equal forces, this twin-rod configuration is optimal. Confirm your ordering essentials: 70mm stroke, PT1/4 port, male M18x1.5 rod thread, and the integrated magnet.
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 ACQD63X70SB FAQ
The push and pull forces are equal at 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum of 286kgf at 1.0MPa. This equality occurs because the double-rod design creates the same annular piston area in both directions. The maximum standard stroke available for a 63mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, not adjustable air cushions. A plain ACQ-type cylinder does not hold its load if air pressure is lost; the rod will drift. For fail-safe holding, you must install an external rod lock or a pilot-operated check valve.
