Airtac ACQD Double Acting Compact Cylinder ACQD63X250S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X250S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 250mm 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 ACQD63X250S
The AirTAC ACQD63X250S is a double-acting JIS compact cylinder featuring twin rods that exit both ends, yielding an identical annular area in each chamber. This symmetry delivers an equal push and pull force of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, ideal for symmetric transfer cycles. A 250mm stroke makes this a made-to-order long-stroke variant exceeding the 100mm standard maximum for this bore.
Two Ø20mm rods resist rotation and extend the guide length, allowing a tool platform to mount directly without an external guide. The second rod end can drive a sensor flag or a secondary load. NBR elastomer bumpers fixed at each end decelerate motion near stroke limits, while the -S magnet works with reed or solid-state switches in the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD63X250S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X250S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 250 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 ACQD63X250S Is Used
Twin-Guided Pusher
Drives a long 250mm stamping or machining head on a CNC lathe, using the dual rods to prevent platform rotation without an external guide rail.
Symmetric Transfer
Actuates a 1401.5N equal-force clamping and release station on an automotive assembly line, ensuring identical cycle dynamics in both directions.
Dual-Station Actuation
Indexes a packaging machine diverter gate where the primary rod moves the gate and the secondary rod end mounts a solid-state sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X250S the Right Cylinder?
Selecting this 63mm bore actuator involves comparing adjacent sizes: the 50mm bore yields 824.6N and the 80mm bore yields 2267.8N at 0.5MPa. Choose the ACQD63X250S when your application demands 1401.5N symmetric thrust over an extended 250mm travel. If your mechanism only requires single-direction work, a single-rod ACQ fits better. For pure vertical lifting without air pressure, a guided TACQ or an external pilot check valve is required since a plain ACQD drifts on air loss. Confirm the PT1/4 port and M10x1.5 female rod-end thread 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 ACQD63X250S 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. Push equals pull because the twin rods occupy both chambers, creating the same annular area each way. The 250mm stroke is a long-stroke made-to-order variant, exceeding the 100mm standard maximum for this 63mm bore.
The two protruding rods resist rotational torque and provide a longer guide length for mounted tools. The -S magnet in the piston works with reed or electronic solid-state switches fitted into the body grooves. Instead of adjustable air cushions, fixed NBR elastomer bumpers absorb impact at the stroke ends; for high energy loads, slow the approach or add an external shock absorber.
