Airtac ACQD Double Acting Compact Cylinder ACQD25X75
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X75 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 75mm 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 ACQD25X75
The AirTAC ACQD25X75 is a double-acting JIS compact cylinder where a Ø12mm piston rod protrudes from both ends of the body. Because a rod occupies both internal chambers, the effective annular area is identical in each direction, yielding perfectly equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa. This symmetry is ideal for applications requiring consistent bi-directional thrust.
The twin-rod design inherently resists rotation and provides a longer guide length, allowing you to mount a small tool platform directly without needing a separate anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. It uses a fixed TPU elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Please note this specific configuration ships without a magnet, though the body retains magnetic-switch grooves, and it does not hold position if air pressure is lost.
Airtac ACQD Double Acting Compact Cylinder ACQD25X75 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X75 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 75 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø25mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 189 N | 189 N |
| 0.7 MPa | 264 N | 264 N |
| Max (@1.0 MPa) | 39 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 ACQD25X75 Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer arm in packaging machinery, using the twin rods to maintain platform alignment and equal force during part handoff.
Dual-Station Actuation
Actuates two separate test probes simultaneously from a single compact body, utilizing the second rod end to drive a secondary load.
Twin-Guided Stripper
Lifts a stripper plate in a small stamping die, relying on the built-in anti-rotation properties of the dual rods to prevent tool binding.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X75 the Right Cylinder?
When sizing this 25mm bore, consider the neighbouring bores: a 20mm bore yields 117.8N at 0.5MPa, while a 32mm bore yields 301.6N. The 25mm provides a balanced 188.9N thrust. If your application requires a single protruding rod or inherently unequal push/pull forces, the standard single-rod ACQ series is a better fit. For heavier radial loads needing precise external linear guidance, a guided TACQ cylinder is recommended. To order, confirm the 75mm stroke, the default female M6x1.0 rod-end thread, and the M5x0.8 PT port.
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 ACQD25X75 FAQ
The ACQD25X75 provides equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa, with a maximum force of 39kgf at 1.0MPa. Push and pull forces are identical because the rod occupies both chambers, creating equal annular areas. The maximum standard stroke for this 25mm bore is 100mm. It features a Ø12mm rod, an M5x0.8 port, and a female M6x1.0 rod-end thread.
No, it uses a fixed TPU elastomer bumper at each end for deceleration, not an adjustable air cushion. For high kinetic energy loads, an external shock absorber is required. Additionally, this specific model ships without a sensor magnet, though the body retains grooves for mounting reed or solid-state switches. A plain ACQD does not hold its load on air loss; use an external rod lock or pilot check valve for fail-safe holding.
