Airtac ACQD Double Acting Compact Cylinder ACQD32X40
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD32X40 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø32mm 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 ACQD32X40
The AirTAC ACQD32X40 is a double-acting JIS compact cylinder featuring twin rods that exit both ends of the riveted body. Because a piston rod occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 301.6N at 0.5MPa and 422.2N at 0.7MPa. This symmetry is ideal for applications requiring balanced bidirectional cycles. The dual rods also prevent rotation and provide an extended guide length, allowing a 32mm bore platform to carry small tools without a separate external guide. The second rod end can drive a sensor flag or a secondary load. This variant ships without a magnet, though the body retains switch grooves. It uses a PT1/8 port and a female M8x1.25 rod-end thread. Deceleration is handled by fixed NBR bumpers at both stroke ends, not adjustable air cushions. A plain compact cylinder does not hold position on air loss; for fail-safe load holding, an external rod lock or pilot check valve is required.
Airtac ACQD Double Acting Compact Cylinder ACQD32X40 Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 40 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 (Ø32mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 302 N | 302 N |
| 0.7 MPa | 422 N | 422 N |
| Max (@1.0 MPa) | 62 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 ACQD32X40 Is Used
Symmetric Transfer Pusher
Drives a dual-sided workpiece transfer head in packaging machinery, leveraging equal 301.6N push and pull forces at 0.5MPa for balanced loading and unloading cycles.
Twin-Guided Stamping Platform
Carries a small stamping or marking tool on a 32mm twin-rod bed, using the inherent anti-rotation properties to maintain tool alignment without an external guide rail.
Dual-Station Actuation
Powers a dual-station clamping fixture on an electronics assembly line, using the second protruding rod end to trip a mechanical valve or external flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD32X40 the Right Cylinder?
At 0.5MPa this 32mm bore generates 301.6N of equal force both ways. If your load needs less thrust, stepping down to the 25mm bore yields 188.9N. For heavier pushing or pulling, the 40mm bore provides 527.8N. The 40mm stroke sits well within the 100mm maximum standard limit for this bore. Choose a single-rod ACQ if equal bidirectional force is unnecessary, or a guided TACQ when your load drastically exceeds the twin rods' torsional limits. To order, confirm the 32mm bore, 40mm stroke, default female M8x1.25 rod thread, PT1/8 port, and the absence of the -S magnet option.
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 ACQD32X40 FAQ
The ACQD32X40 generates equal push and pull forces of 301.6N at 0.5MPa and 422.2N at 0.7MPa, with a maximum holding force of 61kgf at 1.0MPa. Push and pull are equal because the twin rods create identical annular areas in both chambers. The maximum standard stroke available for the 32mm bore is 100mm.
Deceleration at stroke ends relies on fixed NBR elastomer bumpers, not adjustable air cushions; for high-energy impacts, slow the approach or use an external shock absorber. Additionally, a plain ACQD does not hold its load if air pressure is lost or a valve is centered, so an external rod lock or pilot check valve is required for fail-safe positioning.
