Airtac ACQD Double Acting Compact Cylinder ACQD100X40
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD100X40 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø100mm bore and 40mm 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 ACQD100X40
The ACQD100X40 is a JIS double-acting compact cylinder with twin rods extending from both ends. Because a rod occupies each chamber, the annular piston area is identical in both directions, yielding equal push and pull thrust of 3524.8N at 0.5MPa and 4934.8N at 0.7MPa. This bore 100mm unit uses a Ø32mm rod, PT3/8 ports, and a female M20x2.5 rod-end thread.
Dual rods provide a longer guide length and high torsional resistance, allowing you to mount a tool platform directly without adding an external anti-rotation guide. The second rod end can drive a second load or sensor flag. Deceleration relies on fixed NBR elastomer bumpers at both ends, not adjustable air cushions. Note that this variant ships without a magnet, though the body retains switch grooves for adding sensors later.
Airtac ACQD Double Acting Compact Cylinder ACQD100X40 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD100X40 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 40 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 ACQD100X40 Is Used
Twin-Guided Press Tool
Drives a heavy stamping die on a metalworking line where the dual rods prevent deflection and maintain precise parallelism under high 4934.8N loads.
Symmetric Transfer Carriage
Shifts large automotive subassemblies between machining stations, using the second protruding rod end to mirror a secondary conveyor movement simultaneously.
Dual-Station Actuation
Powers a heavy-duty packaging press that must push and pull identical 3524.8N loads, ensuring perfectly balanced dwell times without twisting.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD100X40 the Right Cylinder?
For 0.5MPa operations, this 100mm bore generates 3524.8N both ways; stepping down to an 80mm bore yields 2267.8N, while moving up to a 125mm bore provides 5733.8N. Choose this specific 40mm stroke when your fixture requires massive equal-force cycling within a short 100mm maximum standard stroke envelope. If your load must resist drift during a compressed air failure, remember this cylinder needs an external rod lock or pilot check valve, as the fixed bumper only decelerates near stroke end. Select female rod-end M20x2.5 mounting and PT3/8 pneumatic connections for your 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 ACQD100X40 FAQ
The push and pull forces are equal because the twin rods create matching annular areas. It outputs 3524.8N at 0.5MPa and 4934.8N at 0.7MPa, with a maximum of 719kgf at 1.0MPa. The maximum standard stroke available for this 100mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, not adjustable air cushions. For high kinetic energy, slow the approach speed or use an external shock absorber. It does not hold position on air loss; you must add an external rod lock or pilot check valve for fail-safe load holding.
