Airtac ACQD Double Acting Compact Cylinder ACQD25X30SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X30SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 30mm 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 ACQD25X30SB
The AirTAC ACQD25X30SB is a double-acting JIS compact cylinder featuring a Ø12 mm piston rod protruding from both ends. Because a rod occupies each internal chamber, the effective annular area remains identical on extension and retraction. This geometry yields exactly 188.9 N of force at 0.5 MPa and 264.5 N at 0.7 MPa in either direction, enabling perfectly symmetric push and pull cycles without force drop.
Equipped with a male M10x1.25 rod thread (-B) and a piston magnet (-S), it couples directly to tooling while supporting both reed and solid-state electronic switches. The fixed TPU elastomer bumper decelerates motion at stroke limits, and the twin-rod layout provides extended guide length to prevent rotation. Standard M5x0.8 ports supply air within a 0.15-1.0 MPa operating range.
Airtac ACQD Double Acting Compact Cylinder ACQD25X30SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X30SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 30 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 ACQD25X30SB Is Used
Symmetric Transfer Arms
Drives dual-sided pick-and-place arms in electronics assembly where equal push and pull forces prevent tool deflection during bidirectional travel.
Twin-Guided Pusher Stations
Positions components on a PCB conveyor without needing a separate external guide, as the dual rods inherently resist torsional load and rotation.
Dual-Station Actuation
Uses the second protruding rod end to trigger a solid-state sensor flag on a packaging machine while simultaneously driving the primary clamp.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X30SB the Right Cylinder?
When sizing this 25 mm bore unit, compare its 188.9 N @0.5 MPa output against the 20 mm bore (117.8 N) for lighter duties, or step up to the 32 mm bore (301.6 N) when higher mass is involved. If your mechanism already features an external anti-rotation guide and only needs unidirectional thrust, a single-rod ACQ cylinder may suffice. For this configuration, confirm the 30 mm stroke, the male M10x1.25 rod end, and the M5x0.8 pneumatic port connections. Note that a plain ACQD will drift if air pressure is lost; apply an external rod lock or pilot check valve if fail-safe holding is mandatory.
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 ACQD25X30SB FAQ
This double-acting cylinder provides an equal push and pull force of 188.9 N at 0.5 MPa and 264.5 N at 0.7 MPa, with a maximum holding capacity of 39 kgf at 1.0 MPa. The push and pull forces are identical because the rod occupies both internal chambers, creating the same annular area in each direction. The standard stroke limit for this 25 mm bore is 100 mm.
The twin-rod design inherently resists rotation and extends guide length. It uses fixed TPU elastomer bumpers at both ends for deceleration rather than adjustable air cushions. The -S option includes a built-in piston magnet for mounting reed or electronic switches directly in the body grooves, and the -B option provides a male M10x1.25 thread for direct load coupling.
