Airtac ACQD Double Acting Compact Cylinder ACQD25X35SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X35SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 35mm 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 ACQD25X35SB
The AirTAC ACQD25X35SB is a double-acting JIS compact cylinder featuring a 12mm piston rod extending from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, giving an equal push and pull force of 188.9N at 0.5MPa and 264.5N at 0.7MPa. This symmetric thrust is ideal for synchronized bidirectional cycles.
The twin rods provide extended guide length and high torsional resistance, allowing you to mount a small tool platform directly without needing an external anti-rotation guide. This SB variant includes a male M10x1.25 rod end thread for direct load coupling, a built-in piston magnet for position sensing, and fixed TPU bumpers at both ends to soften end-of-stroke impacts.
Airtac ACQD Double Acting Compact Cylinder ACQD25X35SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X35SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 35 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 ACQD25X35SB Is Used
Symmetric Transfer Pusher
Drives a dual-sided pick-and-place head in electronics assembly, utilizing the equal bidirectional 264.5N force for consistent forward and retract motions.
Twin-Guided Strip Ejector
Ejects metal strips from a stamping die where the twin rods prevent platform yaw without requiring a separate external guide bushing.
Dual-Station Actuator
Powers a small loading shuttle on a packaging machine, using the second protruding rod end to mechanically trigger a physical sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X35SB the Right Cylinder?
Select this 25mm bore if your application requires 188.9N of symmetric thrust at 0.5MPa. Stepping down to a 20mm bore drops the force to 117.8N, while moving up to a 32mm bore increases it to 301.6N. A single-rod ACQ cylinder is preferable if you only need standard extension strokes with higher forward thrust. For heavier lateral loads, consider a guided TACQ cylinder. Confirm your ordering essentials: this SB configuration supplies a male M10x1.25 rod thread, an M5x0.8 PT port, and a 35mm stroke.
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 ACQD25X35SB FAQ
The ACQD25X35SB provides an equal push and pull force of 188.9N at 0.5MPa and 264.5N at 0.7MPa, with a maximum load capacity of 39kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 25mm bore is 100mm.
The twin rods resist torsional rotation and add guide length. It uses fixed TPU elastomer bumpers at both ends for impact absorption, not adjustable air cushions. The S option includes a piston magnet compatible with both reed and electronic solid-state switches, while the B option provides a male M10x1.25 rod thread for direct mounting.
