Airtac ACQD Double Acting Compact Cylinder ACQD20X25B
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X25B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 25mm 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 ACQD20X25B
The AirTAC ACQD20X25B is a double-acting JIS compact cylinder featuring a 10mm piston rod extending from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, generating an equal push and pull force of 117.8N at 0.5MPa. This symmetric thrust is ideal for applications requiring consistent cycling in both directions.
Twin rods resist rotation and provide a longer guide length, allowing you to carry a small tool platform without needing an external anti-rotation guide. This specific unit includes male M8x1.25 rod-end threads for direct load coupling, fixed TPU bumpers for end-of-stroke deceleration, and a 25mm stroke within a space-saving riveted body.
Airtac ACQD Double Acting Compact Cylinder ACQD20X25B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X25B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 25 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø20mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 118 N | 118 N |
| 0.7 MPa | 165 N | 165 N |
| Max (@1.0 MPa) | 24 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 ACQD20X25B Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place arm in electronics assembly, utilizing the equal push and pull thrust for consistent part placement.
Twin-Guided Pusher
Pushes cardboard cartons on a packaging line where the dual rods prevent jaw rotation without needing a separate external guide.
Dual-Station Actuation
Actuates a secondary sensor flag or second load from the opposite rod end on a textile machine, saving space and simplifying layout.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X25B the Right Cylinder?
At 0.5MPa, this 20mm bore yields 117.8N of thrust both ways. Stepping down to a 16mm bore reduces the force to 75.4N, while moving up to a 25mm bore increases it to 188.9N. If your application does not require equal push/pull force or anti-rotation, a standard single-rod ACQ20 cylinder offers a more compact footprint. For heavier lateral loads exceeding the twin-rod guide capacity, a guided TACQ module provides enhanced stability. When ordering, confirm the 25mm stroke, M5x0.8 port size, and the male M8x1.25 rod threads.
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 ACQD20X25B FAQ
It delivers an equal push and pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum capacity of 24kgf at 1.0MPa. Push and pull forces are equal because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 20mm bore is 100mm.
It uses fixed TPU elastomer bumpers at both ends to absorb impact, which are not adjustable; for high-speed loads, an external shock absorber is recommended. A plain ACQ-type cylinder does not hold its load if air pressure is lost, so a fail-safe setup requires an external rod lock or pilot-operated check valve.
