Airtac ACQD Double Acting Compact Cylinder ACQD40X30B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD40X30B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø40mm bore and 30mm 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 ACQD40X30B
The AirTAC ACQD40X30B is a double-acting JIS compact cylinder featuring twin rods that exit from both ends of the riveted body. Because a rod occupies each chamber, the annular area is identical in both directions, generating an equal 527.8 N of thrust and pull force at 0.5 MPa. This symmetric power is ideal for balanced actuation cycles where the return stroke must do real work.
Equipped with a male M14x1.5 rod-end thread on its Ø16 mm pistons, this variant couples directly to tooling platforms. The extended guide length provided by the dual rods prevents twisting without requiring an external anti-rotation guide. Deceleration is handled by fixed NBR elastomer bumpers at both ends, while the body retains sensor grooves for future automation upgrades.
Airtac ACQD Double Acting Compact Cylinder ACQD40X30B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD40X30B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 30 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 ACQD40X30B Is Used
Symmetric Transfer Shuttle
Drives a dual-sided packaging shuttle where matching push and pull forces prevent part skewing during high-speed product transfers.
Twin-Guided Tooling Platform
Carries a machining fixture on a CNC loader, utilizing the dual rods to resist torsional loads without adding a separate external guide rail.
Dual-Station Actuation
Powers a secondary stamping head from the opposite rod end on an automated assembly line, synchronizing two operations from one compact body.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD40X30B the Right Cylinder?
Select this 40 mm bore if your mechanism requires 527.8 N of force in both travel directions across a 30 mm span. Stepping down to a 32 mm bore drops the bidirectional output to 301.6 N, whereas a 50 mm bore raises it to 824.6 N at 0.5 MPa. If your application only needs heavy forward thrust, a single-rod ACQ provides higher push than pull. For multi-axis stability without external guides, this twin-rod configuration is the correct choice. Confirm your ordering code includes the B suffix for the male M14x1.5 thread and PT1/8 porting.
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 ACQD40X30B FAQ
This double-acting cylinder provides an equal push and pull force of 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a maximum capacity of 108 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The standard stroke limit for this 40 mm bore is 100 mm.
It uses fixed NBR elastomer bumpers at both ends to absorb impact, meaning there is no adjustable air cushion. For high kinetic energy loads, an external shock absorber is recommended. Additionally, a plain ACQ-type cylinder does not hold its load if air pressure is lost; you must add an external rod lock or pilot-operated check valve for fail-safe positioning.
