Airtac ACQD Double Acting Compact Cylinder ACQD63X300SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X300SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 300mm 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 ACQD63X300SB
The AirTAC ACQD63X300SB is a double-acting JIS compact cylinder featuring a 63mm bore and a 300mm stroke. Because twin rods protrude from both ends, the annular piston area remains identical in each direction, yielding perfectly equal thrust and retraction forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This symmetric output is ideal for balanced cycling, and the extra rod can drive a secondary load or sensor flag.
Built with a robust C-clip body, this variant includes an S magnet for electronic or reed switches and B male M18x1.5 rod threads for direct mounting. It uses a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Note that the 300mm stroke is a made-to-order long-stroke configuration, exceeding the standard 100mm maximum for this bore.
Airtac ACQD Double Acting Compact Cylinder ACQD63X300SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X300SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 300 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 ACQD63X300SB Is Used
Symmetric Transfer Shuttle
Drives a dual-sided packaging shuttle where equal push and pull thrust ensures stable, balanced product transfer across a 300mm gap without rotational drift.
Twin-Guided Pusher Array
Actuates a multi-stage electronics assembly pusher, using the second rod end to mount a physical sensor flag for precise mid-stroke position confirmation.
Dual-Station Actuation
Powers a long-reach clamping station on an automotive fixture, utilizing the male M18x1.5 threads to secure a tooling platform directly to both rod ends.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X300SB the Right Cylinder?
Selecting this 63mm bore model provides 1401.5N of equal bidirectional force at 0.5MPa. If your application requires less thrust, the adjacent 50mm bore delivers 824.6N; stepping up to the 80mm bore provides 2267.8N. A single-rod ACQ cylinder is preferable if you only need standard push action and asymmetric force. For this 300mm extended travel length, ensure your load is guided externally if side loads are high, as the fixed bumpers only absorb impact energy near the stroke endpoints. Confirm the PT1/4 port size and M18x1.5 male threads during 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 ACQD63X300SB FAQ
This cylinder provides equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum holding capacity of 286kgf at 1.0MPa. The equal force is due to the double-rod design creating the same annular area in both directions. It features a 300mm made-to-order long stroke (exceeding the 100mm standard max), a PT1/4 port, and M18x1.5 male rod threads.
The twin rods resist rotation and provide extended guide length without needing an external anti-rotation guide. It uses fixed NBR elastomer bumpers at both ends for deceleration, not adjustable air cushions. A plain ACQD does not hold its load if air pressure is lost; for fail-safe positioning, you must install an external rod lock or pilot-operated check valve.
