Airtac ACQD Double Acting Compact Cylinder ACQD63X35B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X35B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 35mm 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 ACQD63X35B
The AirTAC ACQD63X35B is a double-acting JIS compact cylinder featuring twin rods that exit from both body ends. Because a piston rod occupies each chamber, the effective annular area is identical in both directions, yielding perfectly equal push and pull forces of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. This symmetry eliminates force differential issues during bidirectional cycling, while the parallel rods drastically resist rotation and extend the guiding length without requiring a separate external guide.
This 63 mm bore unit incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. It features a PT1/4 port and a male M18x1.5 rod-end thread (-B option) for direct load coupling. The body retains integrated magnetic-switch grooves, though this specific configuration ships without a piston magnet. Operating pressure spans 0.15-1.0 MPa, with a maximum standard stroke capacity of 100 mm for this bore size.
Airtac ACQD Double Acting Compact Cylinder ACQD63X35B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X35B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 35 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 ACQD63X35B Is Used
Symmetric Transfer Shuttle
Drives a dual-sided parts shuttle on packaging machinery, utilizing the second rod end to mirror a synchronized pick-and-place motion without rotational deflection.
Twin-Guided Pusher Station
Actuates a multi-stage pusher on an assembly line, where the twin rods carry a wide tooling plate directly, negating the need for a separate external anti-rotation guide.
Dual-Station Actuation
Powers a dual-station clamping fixture in CNC machining, using the equal 1962.2 N force at 0.7 MPa to secure parts identically in both extend and retract directions.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X35B the Right Cylinder?
When sizing this 63 mm bore actuator, consider the neighboring bores for your force requirements: the 50 mm variant provides 824.6 N at 0.5 MPa, while the 80 mm version yields 2267.8 N at 0.5 MPa. If your application only requires unidirectional thrust and allows rotational play, a single-rod ACQ cylinder might suffice. However, if you need precise multi-axis stability or a secondary attachment point, this double-rod configuration is superior. Remember that a plain ACQ-type cylinder will not hold a load if air pressure is lost; for fail-safe positioning, an external rod lock or pilot-operated check valve is required. Confirm the 35 mm stroke, male M18x1.5 thread, and PT1/4 port 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 ACQD63X35B FAQ
The ACQD63X35B 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 capacity of 286 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods occupy both chambers, creating the same effective annular area in each direction. The maximum standard stroke available for this 63 mm bore is 100 mm.
Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions; for high kinetic energy loads, an external shock absorber is recommended. The body includes grooves for reed or solid-state switches, but this specific model ships without a piston magnet (-S option omitted). Additionally, it features a male M18x1.5 rod-end thread for direct coupling.
