Airtac ACQD Double Acting Compact Cylinder ACQD63X25SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X25SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 25mm 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 ACQD63X25SB
The AirTAC ACQD63X25SB is a double-acting JIS compact cylinder where a piston rod protrudes from both ends. Because a rod occupies each chamber, the effective 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 is ideal for applications requiring consistent bi-directional thrust up to a maximum of 286 kgf at 1.0 MPa.
Twin rods resist rotation and provide a longer 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 version includes a male M18x1.5 rod-end thread (-B) for direct coupling, a built-in piston magnet (-S) for position sensing, and fixed NBR elastomer bumpers at both ends. It operates at 30-500 mm/s with PT1/4 ports.
Airtac ACQD Double Acting Compact Cylinder ACQD63X25SB Technical Specifications

| Bore size | Ø63 mm |
| Stroke | 25 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 ACQD63X25SB Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer carriage on a packaging line, utilizing the equal push and pull forces to move components consistently in both directions without thrust imbalance.
Twin-Guided Pick & Place
Lifts and places electronic components using a tooling plate mounted to the twin rods, leveraging the extended guide length to prevent rotational torque without external guide rails.
Dual-Station Actuation
Powers a dual-station clamping fixture on an automotive machining center, using the second protruding rod end to trigger a solid-state sensor flag for cycle confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X25SB the Right Cylinder?
Selecting this 63mm bore provides 1401.5 N of equal force both ways at 0.5 MPa. Stepping down to a 50mm bore drops the output to 824.6 N, while moving up to an 80mm bore increases it to 2267.8 N. If your application does not require equal push/pull force or twin-rod anti-rotation, a standard single-rod ACQ cylinder may suffice and save space. For loads requiring precise linear guidance over a longer distance, a guided TACQ cylinder might be a better fit. When ordering, confirm the 25mm stroke, the male M18x1.5 thread, and the magnet requirement.
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 ACQD63X25SB FAQ
The ACQD63X25SB delivers equal push and pull forces 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 equals pull because the rod occupies both chambers, creating identical annular areas. The maximum standard stroke for a 63mm bore is 100mm. It features a male M18x1.5 rod-end thread and a PT1/4 port.
No, a plain ACQD does not hold position when air is lost; the rod will drift and the fixed NBR elastomer bumper only decelerates the piston near the stroke end. For fail-safe load holding, an external rod lock or pilot-operated check valve is required. The fixed bumpers are not adjustable air cushions, so for high-energy cycles, you should slow the approach speed or add an external shock absorber.
