Airtac ACQD Double Acting Compact Cylinder ACQD63X125S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X125S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 125mm 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 ACQD63X125S
The AirTAC ACQD63X125S is a double-acting JIS compact cylinder featuring twin Ø20mm rods exiting both ends. Because a rod occupies each chamber, the effective annular area is identical on extension and retraction, yielding perfectly symmetric push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This 125mm stroke is a made-to-order long-stroke variant, exceeding the 100mm standard maximum for this bore.
The dual-rod architecture inherently resists torsional rotation and provides an extended guide length, allowing you to mount a tooling platform directly without needing an external anti-rotation guide. The second rod end can simultaneously drive a secondary load or a sensor flag. Deceleration is handled by fixed NBR elastomer bumpers inside the compact riveted body, and the integrated piston magnet (-S) supports both reed and solid-state electronic switches.
Airtac ACQD Double Acting Compact Cylinder ACQD63X125S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X125S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 125 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 ACQD63X125S Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer carriage on a packaging line, utilizing the equal push and pull forces to maintain perfectly balanced indexing without rotational drift.
Twin-Guided Stamping Press
Mounts a small stamping tool directly to the protruding rods in an electronics fab, leveraging the extended guide length to resist torsional deflection during precise pressing.
Dual-Station Actuation
Powers two adjacent clamping stations simultaneously from a single compact body on an automotive component assembly machine, using the second rod end to mount a position sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X125S the Right Cylinder?
Choosing this 63mm bore provides 1401.5N of equal bidirectional force at 0.5MPa. If your application requires less push, the adjacent 50mm bore yields 824.6N, while stepping up to the 80mm bore provides 2267.8N for heavier demands. A single-rod ACQ cylinder is preferable if you only need standard unbalanced push force and lack anti-rotation requirements, whereas a fully guided slide unit might be better for very high lateral loads. When ordering, confirm the PT1/4 port, the female M10x1.5 rod-end threads, and the 125mm nonstandard stroke specification.
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 ACQD63X125S FAQ
It delivers an equal push and pull force of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum capacity of 286kgf at 1.0MPa. The push and pull forces are identical because the twin rods create the same annular piston area in both directions. This 125mm unit is a made-to-order long-stroke variant, exceeding the 100mm standard maximum for a 63mm bore.
A standard ACQ-type cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; a fail-safe hold requires an external rod lock or pilot-operated check valve. End-of-stroke deceleration is provided by fixed NBR elastomer bumpers, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
