Airtac ACQD Double Acting Compact Cylinder ACQD40X60
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD40X60 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø40mm bore and 60mm 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 ACQD40X60
The AirTAC ACQD40X60 is a 40mm bore, 60mm stroke double-acting JIS compact cylinder featuring a twin-rod design where a piston rod protrudes from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding perfectly equal push and pull forces of 527.8N at 0.5MPa and 738.9N at 0.7MPa. This symmetry is ideal for applications requiring balanced bidirectional cycling.
The dual Ø16mm rods resist rotation and provide an extended guide length, allowing the unit to support a small tool platform without needing a separate external anti-rotation guide. The compact C-clip and riveted body incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. It features PT1/8 ports and a standard female M8x1.25 rod-end thread, while the second rod end can drive a sensor flag or secondary load.
Airtac ACQD Double Acting Compact Cylinder ACQD40X60 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD40X60 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 60 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 ACQD40X60 Is Used
Twin-Guided Pusher
Drives a dual-rail pusher in packaging machinery, using the symmetrical 738.9N force to shift cartons without rotational torque skewing the guide rails.
Symmetric Transfer
Powers a pick-and-place transfer arm in electronics assembly, leveraging the equal push/pull areas to maintain identical acceleration profiles in both travel directions.
Dual-Station Actuation
Actuates a dual-station clamping fixture on a machining center, using the protruding second rod end to mechanically trigger a remote position flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD40X60 the Right Cylinder?
When sizing this 40mm bore, consider the neighbouring capacities: stepping down to a 32mm bore yields 301.6N at 0.5MPa, while stepping up to a 50mm bore provides 824.6N at 0.5MPa. If your mechanism only needs unidirectional thrust where push exceeds pull, a single-rod ACQ series is more appropriate. For loads requiring precise lateral stability over a longer span, a guided TACQ profile might fit better. To order, confirm the 60mm stroke, female M8x1.25 rod thread, PT1/8 port, and note this specific SKU ships without a magnet (-S omitted) though switch grooves remain machined into the body.
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 ACQD40X60 FAQ
The ACQD40X60 operates on 0.15-1.0 MPa air pressure and delivers an equal push and pull force of 527.8N at 0.5MPa or 738.9N at 0.7MPa, with a maximum holding capacity of 108kgf at 1.0MPa. Push and pull forces are identical because the twin rods create the same annular piston area in both chambers. The maximum standard stroke available for this 40mm bore is 100mm.
The twin Ø16mm rods inherently resist rotation and extend the guide length, eliminating the need for an external anti-rotation guide. It uses fixed NBR elastomer bumpers at both ends for impact absorption, not adjustable air cushions. Note that a plain ACQD does not hold its load if air pressure is lost; for fail-safe position holding, you must install an external rod lock or pilot-operated check valve.
