Airtac ACQD Double Acting Compact Cylinder ACQD40X300
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD40X300 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø40mm bore and 300mm 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 ACQD40X300
The AirTAC ACQD40X300 is a double-acting JIS compact cylinder featuring a twin-rod design where a shaft exits both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding 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 loading.
This 40mm bore variant features a Ø16mm piston rod, PT1/8 port, and an M8x1.25 female rod-end thread. The extended 300mm stroke is a made-to-order long-stroke configuration exceeding the 100mm standard maximum. It includes fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. Note that this unit ships without a magnet, though the body retains sensor grooves for adding external switches. It does not hold position on air loss without an external rod lock or pilot check valve.
Airtac ACQD Double Acting Compact Cylinder ACQD40X300 Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 300 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 ACQD40X300 Is Used
Twin-Guided Pusher
Drives an extended 300mm transfer carriage in packaging machinery, using the dual shafts to prevent platform twisting without needing a separate external guide rail.
Symmetric Transfer
Executes balanced push and pull cycles on an assembly line fixture, leveraging the equal 527.8N annular force to ensure identical clamping pressure in both directions.
Dual-Station Actuation
Powers a secondary sensor flag or load on the opposite rod end for a large-format electronics handling machine, synchronizing two process stations across a long 300mm travel.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD40X300 the Right Cylinder?
Selecting this 40mm bore long-stroke model provides 527.8N of equal bidirectional force at 0.5MPa. If your application requires less force, scaling down to the 32mm bore yields 301.6N, while stepping up to the 50mm bore provides 824.6N. A single-rod ACQ cylinder is preferable if you need higher extension force than retraction force, or a guided TACQ fits better if you need external rotational resistance beyond what the twin rods provide. When ordering, confirm the 300mm made-to-order stroke, the default female M8x1.25 rod thread, and the PT1/8 pneumatic connection.
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 ACQD40X300 FAQ
The push and pull forces are equal at 527.8N @0.5MPa and 738.9N @0.7MPa, with a maximum load of 108kgf @1.0MPa. Because a rod exits both ends, the annular piston area is identical in each direction, making push and pull forces perfectly symmetrical. The 300mm stroke is a made-to-order long-stroke variant that exceeds the 100mm standard maximum for this 40mm bore.
The twin-rod structure inherently resists rotation and provides a longer guide length for the tool platform. It uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions; for high-speed 300mm travel, an external shock absorber is recommended. This specific model ships without a magnet, but the body retains grooves so you can mount reed or solid-state electronic switches externally if needed.
