Airtac ACQD Double Acting Compact Cylinder ACQD40X100B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD40X100B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø40mm bore and 100mm 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 ACQD40X100B
The AirTAC ACQD40X100B is a double-acting JIS compact cylinder featuring twin rods extending from both body ends. Because a rod occupies each chamber, the annular areas match, generating identical push and pull forces of 527.8N at 0.5MPa and 738.9N at 0.7MPa. This symmetry is ideal for cycles requiring perfectly balanced bi-directional thrust. The unit hits a maximum thrust of 108kgf at 1.0MPa.
Twin rods inherently resist rotation and extend guiding length, letting you mount a tool platform directly without adding a separate anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. This 40mm bore variant uses a 16mm piston rod with PT1/8 ports and an M14x1.5 male thread (-B) for direct coupling. It relies on fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions.
Airtac ACQD Double Acting Compact Cylinder ACQD40X100B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD40X100B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 100 mm |
| Acting type | Double acting, double rod |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | 739 N |
| Max (@1.0 MPa) | 108 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 ACQD40X100B Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place shuttle in packaging lines, leveraging the equal push and pull thrust for consistent bi-directional timing.
Twin-Guided Pusher
Indexes parts on an assembly conveyor without twisting, using the inherent anti-rotation properties of the dual rods to maintain tool alignment.
Dual-Station Actuation
Simultaneously operates two separate clamps on a CNC machining fixture, using the second protruding rod end to actuate the secondary mechanism.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD40X100B the Right Cylinder?
Providing 527.8N of thrust at 0.5MPa, this 40mm bore model sits between the 32mm bore (301.6N) and the 50mm bore (824.6N). Choose this 100mm stroke variant for full 100mm standard travel limits. If your application only needs unidirectional push force, a single-rod ACQ might save space, while a guided TACQ fits better for heavy lateral loads. This configuration ships without a magnet (-S omitted) but retains body sensor grooves for adding reed or solid-state switches later. The male M14x1.5 rod thread ensures rigid load coupling.
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 ACQD40X100B FAQ
It delivers an equal push and pull force of 527.8N at 0.5MPa and 738.9N at 0.7MPa, with a maximum thrust of 108kgf at 1.0MPa. Push and pull forces are identical because the rod occupies both chambers, making the effective annular area the same in each direction. The maximum standard stroke for this 40mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends for impact absorption, not adjustable air cushions. A plain ACQD does not hold its position if air pressure is lost; the rod will drift. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
