Airtac ACQD Double Acting Compact Cylinder ACQD63X25S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X25S 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 ACQD63X25S
The AirTAC ACQD63X25S is a double-acting JIS compact cylinder featuring twin rods that exit from both ends of the body. Because a rod occupies each internal chamber, the effective annular area is identical in both directions. This yields equal push and pull forces of 1401.5 N at 0.5 MPa, enabling perfectly symmetric cycle movements without differential thrust.
The dual rods inherently resist rotation and provide an extended guide length, eliminating the need for a separate external anti-rotation guide for small tool platforms. The second rod end can drive a sensor flag or a secondary load. Built with a fixed NBR elastomer bumper at each end for end-of-stroke deceleration, this 63mm bore unit includes a built-in magnet (-S) compatible with reed or solid-state switches, and features a PT1/4 port.
Airtac ACQD Double Acting Compact Cylinder ACQD63X25S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X25S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| 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 ACQD63X25S Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place head in packaging machinery, utilizing the equal push and pull forces to maintain perfectly balanced horizontal shifting without momentum drift.
Twin-Guided Pusher
Executes straight pushing on a CNC stamping line where the twin rods prevent chassis deflection and resist torsional loads without needing an external linear guide.
Dual-Station Actuation
Powers a two-station clamping fixture on an automated assembly press, using the second protruding rod end to mechanically trigger a physical valve or flag on the opposite side.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X25S the Right Cylinder?
At 0.5 MPa, this 63mm bore generates 1401.5 N of thrust both ways. If your payload is lighter, the 50mm bore provides 824.6 N, saving space. For heavier demands, the 80mm bore yields 2267.8 N. If your application strictly requires non-rotating guidance over a very long stroke, consider a guided TACQ cylinder instead. To order: specify the ACQD63X25S model, confirm the 25mm stroke is within the 100mm maximum, and note the default female M10x1.5 rod end thread with PT1/4 piping.
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 ACQD63X25S FAQ
The cylinder provides 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 capacity of 286 kgf at 1.0 MPa. Because the rod occupies both chambers, the annular area is identical in each direction, making thrust equal both ways. The maximum standard stroke for this 63mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends for impact absorption, not adjustable air cushions. A plain ACQD does not hold its load if air pressure is lost; the rod will drift. For fail-safe position holding, an external rod lock or pilot-operated check valve is required.
