Airtac ACQD Double Acting Compact Cylinder ACQD63X125
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X125 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 ACQD63X125
The AirTAC ACQD63X125 is a double-acting JIS compact cylinder featuring a twin-rod design where a piston rod protrudes from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, generating equal push and pull forces of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. The dual rods inherently resist rotation and provide an extended guide length, allowing a tool platform to be carried directly without needing an external anti-rotation guide.
This 63 mm bore unit features a 125 mm stroke, which exceeds the 100 mm standard maximum and is supplied as a long-stroke made-to-order variant. It incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The body includes magnetic-switch grooves, though this specific configuration ships without the internal magnet. With a Ø20 mm rod, PT1/4 port, and a female M10x1.5 rod-end thread, it operates smoothly between 30-500 mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD63X125 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X125 |
|---|---|
| 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 ACQD63X125 Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer mechanism on a packaging conveyor, utilizing the equal push and pull thrust to move cartons smoothly in both directions without force asymmetry.
Twin-Guided Press Fixture
Carries a small stamping or pressing tool head directly on the second rod end, relying on the extended guide length to prevent deflection during clamping operations.
Dual-Station Actuation
Actuates two separate workstations simultaneously from a single compact body, using the protruding rod at the opposite end to trigger a secondary process or sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X125 the Right Cylinder?
Selecting this 63 mm bore model provides a maximum force of 286 kgf at 1.0 MPa. If your application requires less thrust, the 50 mm bore variant offers 824.6 N at 0.5 MPa, whereas stepping up to the 80 mm bore yields 2267.8 N at 0.5 MPa. The 125 mm stroke is a non-standard long-stroke option; if your space constraints demand a shorter travel, the 100 mm standard maximum is readily available. For applications needing precise non-rotating guidance over a long span, this twin-rod body is ideal, whereas a single-rod ACQ fits simpler push-only tasks. Remember to specify the female M10x1.5 rod thread and 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 ACQD63X125 FAQ
Because it is a double-rod cylinder with equal annular area both ways, push and pull forces are identical: 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, with a maximum of 286 kgf at 1.0 MPa. It features a Ø20 mm rod, a female M10x1.5 rod-end thread, and a PT1/4 port. The 125 mm stroke exceeds the 100 mm standard maximum for this bore, making it a long-stroke made-to-order variant.
A plain ACQD does not hold position when air is lost or a valve is centered; the rod drifts, and an external rod lock or pilot-operated check valve is required for fail-safe holding. For motion control, it uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. For high-energy cycles, you should slow the approach speed or add an external shock absorber.
