Airtac ACQD Double Acting Compact Cylinder ACQD100X250
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD100X250 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 ACQD100X250
The AirTAC ACQD100X250 is a double-acting JIS compact cylinder featuring a 100mm bore and a 250mm stroke. Because twin rods protrude from both ends, the annular piston area remains identical in each direction, delivering equal push and pull forces of 3524.8N at 0.5MPa and 4934.8N at 0.7MPa. This symmetric thrust is ideal for balanced actuation cycles. A fixed NBR elastomer bumper manages end-of-stroke impact, while the extra rod end can drive a secondary load or sensor flag.
This 250mm variant is a long-stroke, made-to-order unit, exceeding the 100mm standard maximum for this bore size. It uses a PT3/8 port and a Ø32mm piston rod with an M20x2.5 female thread. The dual-rod architecture inherently resists rotation and extends guide length, eliminating the need for a separate external anti-rotation guide in many tooling setups.
Airtac ACQD Double Acting Compact Cylinder ACQD100X250 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD100X250 |
|---|---|
| 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 ACQD100X250 Is Used
Twin-Guided Tool Platform
Drives a heavy machining fixture on a CNC lathe, using the dual rods to maintain parallelism and prevent rotational drift under high cutting loads.
Symmetric Transfer Unit
Powers a heavy-duty automotive parts transfer line where identical push and pull forces ensure stable acceleration and deceleration of large castings.
Dual-Station Actuation
Actuates two separate press stations simultaneously from one body, using the second protruding rod end to operate a secondary mechanism or mechanical flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD100X250 the Right Cylinder?
Selecting this 100mm bore provides massive equal thrust up to 719kgf at 1.0MPa. For lower force needs, an 80mm bore yields 2267.8N at 0.5MPa. If your application requires less than 100mm of travel, choose a standard stroke to avoid the made-to-order lead times of this 250mm configuration. If true fail-safe load holding is required during air loss, add an external rod lock or pilot-operated check valve, as the fixed bumper only decelerates near stroke end. Confirm your port and M20x2.5 female rod 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 ACQD100X250 FAQ
It delivers equal push and pull forces of 3524.8N at 0.5MPa and 4934.8N at 0.7MPa, with a maximum thrust of 719kgf at 1.0MPa. Push equals pull because the rods occupy both chambers, creating identical annular areas. The 250mm stroke is a long-stroke, made-to-order variant, as the standard maximum stroke for a 100mm bore is 100mm.
The twin rods exiting both ends provide a longer guide length and inherent anti-rotation resistance without needing an external guide block. At the end of travel, fixed NBR elastomer bumpers absorb impact. Note that this specific model ships without a magnet, though the body retains sensor grooves for adding switches if needed.
