Airtac ACQD Double Acting Compact Cylinder ACQD25X90SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X90SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 90mm 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 ACQD25X90SB
The AirTAC ACQD25X90SB is a double-acting JIS compact cylinder featuring a twin-rod design where a piston rod protrudes from both ends. Because a rod occupies each internal chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa. This symmetric force output is ideal for applications requiring consistent actuation cycles in both directions.
Twin Ø12mm rods inherently resist rotation and provide a longer guide length, allowing you to mount a small tool platform directly without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. This 25mm bore unit includes a male M10x1.25 rod-end thread (-B) for direct coupling, an integrated piston magnet (-S) for electronic or reed switches, and fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration.
Airtac ACQD Double Acting Compact Cylinder ACQD25X90SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X90SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 90 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 ACQD25X90SB Is Used
Symmetric Transfer Pusher
Drives a dual-sided pick-and-place head in electronics assembly, using the equal push and pull forces to ensure consistent part placement pressure on the return stroke.
Twin-Guided Stamping Tool
Mounts a small stamping head directly to the double-rod end on a packaging machine, leveraging the inherent resistance to rotation to maintain stamp alignment without an external guide.
Dual-Station Actuation
Powers a dual-station clamping fixture in woodworking machinery, using the second protruding rod end to mechanically trigger a sequence valve or drive a secondary stopper.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X90SB the Right Cylinder?
Selecting this 25mm bore model provides 188.9N of thrust both ways at 0.5MPa; if your application needs less force, the 20mm bore variant offers 117.8N, while stepping up to the 32mm bore yields 301.6N. The 90mm stroke is well within the 100mm standard maximum for this bore. Choose a single-rod ACQ cylinder if equal bidirectional force and anti-rotation are not required, or a guided TACQ cylinder if your load demands heavy lateral support beyond the twin-rod guidance. Confirm the M5x0.8 port size, male M10x1.25 rod thread, and the requirement for an external rod lock if fail-safe load holding is needed during air loss.
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 ACQD25X90SB FAQ
The ACQD25X90SB delivers an equal push and pull force 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 twin-rod design creates equal annular areas in both chambers. The 90mm stroke is within the 100mm standard maximum for this 25mm bore. It features a male M10x1.25 rod-end thread and an M5x0.8 port.
The -S option includes a built-in piston magnet compatible with both reed and solid-state electronic switches via the body grooves. Deceleration is handled by fixed TPU elastomer bumpers at both ends, not adjustable air cushions, so external shock absorbers may be needed for high-energy loads. A plain ACQD does not hold position on air loss; for fail-safe load holding, an external rod lock or pilot-operated check valve is required.
