Airtac ACQD Double Acting Compact Cylinder ACQD25X25S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X25S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm 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 ACQD25X25S
The AirTAC ACQD25X25S is a double-acting JIS compact cylinder featuring a twin-rod design where a Ø12mm piston rod protrudes from both body ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, generating equal push and pull thrust of 188.9N at 0.5MPa and 264.5N at 0.7MPa. This symmetry is ideal for applications requiring balanced bidirectional force.
The dual rods inherently resist rotation and provide an extended guide length, eliminating the need for a separate external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. Deceleration is handled by fixed TPU elastomer bumpers at each end, and the integrated magnet (-S) supports reed or solid-state switches via the body grooves. Operating pressure spans 0.15-1.0MPa with a speed range of 30-500mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD25X25S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X25S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 25 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 ACQD25X25S Is Used
Symmetric Transfer Pusher
Drives a dual-sided pick-and-place head in electronics assembly, using the equal push and pull thrust to maintain balanced positioning during board transfer.
Twin-Guided Stacking Lift
Elevates a small tooling platform in packaging machinery, relying on the twin rods to prevent rotation without adding an external guide rail.
Dual-Station Actuation
Powers a two-station clamping fixture on a machining center, using the second protruding rod end to trigger a remote position sensor.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X25S the Right Cylinder?
For 0.5MPa operations, this 25mm bore yields 188.9N of thrust both ways; stepping down to a 20mm bore drops the force to 117.8N, while sizing up to a 32mm bore increases it to 301.6N. If your mechanism only needs one-sided actuation, a single-rod ACQ variant saves space, and a guided TACQ fits better for heavy lateral loads. Confirm your porting (M5x0.8) and default female M6x1.0 rod-end threads when ordering.
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 ACQD25X25S FAQ
It delivers equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa, with a maximum holding capacity of 39kgf at 1.0MPa. Push and pull are equal because the twin rods create the same annular area in both chambers. The maximum standard stroke for this 25mm bore is 100mm.
No, a plain ACQD does not hold position on air loss; you must add an external rod lock or pilot check valve for fail-safe holding. Impact deceleration is handled by fixed TPU elastomer bumpers at both ends, which are not adjustable, so external shock absorbers are recommended for high-energy loads.
