Airtac ACQD Double Acting Compact Cylinder ACQD63X35SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X35SB 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 ACQD63X35SB
The AirTAC ACQD63X35SB is a double-acting JIS compact cylinder featuring twin rods exiting both ends. Because a shaft occupies each chamber, the annular piston 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. The extra rod also resists rotation and provides a longer guide length, letting you mount a tool platform directly without needing an external anti-rotation guide.
This 63mm bore unit includes a male M18x1.5 rod-end thread for direct load coupling and a PT1/4 port. It carries a built-in magnet for electronic or reed switches, and relies on fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable cushions. Operating pressure spans 0.15-1.0 MPa, with a maximum speed of 30-500 mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD63X35SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X35SB |
|---|---|
| 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 ACQD63X35SB Is Used
Symmetric Transfer Shuttle
Drives a dual-sided parts shuttle on an assembly line, utilizing the equal push and pull forces to maintain consistent cycle timing in both directions without requiring separate pressure tuning.
Twin-Guided Pick-and-Place
Mounts a gripper plate directly to the protruding second rod end in electronics packaging equipment, leveraging the extended guide length to prevent jaw rotation during vertical placement.
Dual-Station Actuation
Powers a dual-station stamping press where one rod end drives the primary tool and the opposite end actuates a secondary sensor flag, ensuring synchronized machine sequencing.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X35SB the Right Cylinder?
When sizing this 63mm bore, dropping down to the 50mm model reduces the bidirectional force to 824.6 N at 0.5 MPa, while stepping up to the 80mm version increases it to 2267.8 N. This ACQD63X35SB is optimal when your application requires 1401.5 N of symmetric thrust and inherent twist resistance. If your mechanism already has an external linear guide and only needs unidirectional thrust, a single-rod ACQ series cylinder might be a more compact choice. Confirm the 35mm stroke, the male M18x1.5 rod thread, and the PT1/4 porting 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 ACQD63X35SB FAQ
The cylinder generates 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 capacity of 286 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods create the same effective annular area in both chambers. The maximum standard stroke available for this 63mm bore is 100 mm.
It uses fixed NBR elastomer bumpers at both ends for impact absorption rather than adjustable air cushions. A plain ACQD does not hold its load if air pressure is lost; for fail-safe positioning, an external rod lock or pilot-operated check valve is required. The included -S magnet works with both reed and solid-state electronic switches mounted in the body grooves.
