Airtac ACQD Double Acting Compact Cylinder ACQD100X250B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD100X250B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø100mm 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 ACQD100X250B
The ACQD100X250B is a double-acting JIS compact cylinder featuring a 32mm piston rod protruding from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, generating equal push and pull forces of 3524.8N at 0.5MPa and 4934.8N at 0.7MPa. This symmetric thrust is ideal for applications requiring identical drive power in both travel directions. The twin rods also provide extended guiding length and high torsional resistance without needing an external guide.
This made-to-order variant features a 250mm stroke, exceeding the 100mm standard maximum for this 100mm bore size. It includes a male M26x1.5 rod-end thread for direct load coupling and uses a PT3/8 port. Fixed NBR elastomer bumpers at both ends absorb end-of-stroke impact, operating effectively across 0.15-1.0MPa at speeds of 30-500mm/s. Note that this configuration ships without a sensor magnet, though the body retains magnetic switch grooves for external sensors.
Airtac ACQD Double Acting Compact Cylinder ACQD100X250B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD100X250B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 250 mm |
| Acting type | Double acting, double rod |
| Port size | PT3/8 |
| Rod end thread | M20×2.5 female / M26×1.5 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 (Ø100mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 N |
| Max (@1.0 MPa) | 719 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 ACQD100X250B Is Used
Symmetric Transfer Shuttle
Drives a large parts shuttle on an automotive assembly line where identical push and pull thrust ensures precise bi-directional positioning without momentum drift.
Twin-Guided Pusher Array
Pushes heavy pallets in a packaging facility; the dual 32mm rods resist torsional loads entirely, eliminating the need for a separate external guide rail.
Dual-Station Actuation
Actuates two separate clamps on a large metal stamping press simultaneously using both rod ends, maintaining perfect synchronization across the 250mm travel.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD100X250B the Right Cylinder?
Selecting this 100mm bore double-rod actuator involves comparing its 3524.8N equal bidirectional force against adjacent sizes; the 80mm bore provides 2267.8N, while the 125mm bore yields 5733.8N at 0.5MPa. This specific 250mm stroke is a long-stroke variant made-to-order, surpassing the 100mm standard maximum. If your mechanism only needs unidirectional thrust, a single-rod ACQ cylinder offers a more compact footprint, while a guided TACQ might be preferred if the load requires extreme lateral stability beyond what the twin rods provide. Confirm the male M26x1.5 thread and PT3/8 port match your pneumatic setup.
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 ACQD100X250B FAQ
This 100mm bore cylinder provides equal push and pull forces of 3524.8N at 0.5MPa and 4934.8N at 0.7MPa, with a maximum capacity of 719kgf at 1.0MPa. The push and pull forces are equal because the double-rod design creates the same annular area in both chambers. It features a 250mm stroke (a made-to-order long-stroke variant exceeding the 100mm standard max), a 32mm rod, a male M26x1.5 rod thread, and a PT3/8 port.
It uses fixed NBR elastomer bumpers at both ends to absorb impact; these are not adjustable air cushions, so external shock absorbers may be needed for high-energy cycles. Additionally, a plain ACQ-type cylinder does not hold its load if air pressure is lost or the valve is centered, as the rod will drift. For fail-safe load holding, an external rod lock or pilot-operated check valve is required.
