Airtac ACQD Double Acting Compact Cylinder ACQD25X50S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X50S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 50mm 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 ACQD25X50S
The AirTAC ACQD25X50S is a JIS compact double-acting cylinder featuring a 12mm piston rod exiting both ends. Because the rod occupies both chambers, the effective annular area is identical in each direction, yielding equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa. The twin rods resist rotation and provide a longer guide length, allowing you to carry and guide a small tool platform without a separate external guide.
This 25mm bore model includes the -S magnet for position sensing via reed or solid-state switches fitted into the body grooves. It uses a fixed TPU elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Operating pressure spans 0.15-1.0MPa, and the M5x0.8 PT ports supply air to both chambers.
Airtac ACQD Double Acting Compact Cylinder ACQD25X50S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X50S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 50 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 ACQD25X50S Is Used
Twin-Guided Pusher
Mounts a small tooling platform on a CNC lathe loader, using the dual rods to prevent deflection while pushing stock at 264.5N.
Symmetric Transfer Unit
Drives a pick-and-place head on an electronics assembly line, leveraging the identical push and pull annular areas for consistent bidirectional dynamics.
Dual-Station Actuation
Powers a dual-station packaging clamp where the second rod end mounts a sensor flag to trigger a downstream packaging routine simultaneously.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X50S the Right Cylinder?
Selecting this 25mm bore with a 50mm stroke provides 188.9N of force both ways at 0.5MPa. If your payload is lighter, the 20mm bore yields 117.8N, while the heavier 32mm bore provides 301.6N. Choose a single-rod ACQ if you only need unidirectional thrust and want higher forward force. Confirm you need the female M6x1.0 rod-end thread and the -S magnet for electronic or reed switch sensing.
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 ACQD25X50S FAQ
It delivers equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa due to the identical annular area on both sides. The maximum operating pressure is 1.0MPa (yielding 39kgf), and the maximum standard stroke available for this 25mm bore is 100mm.
A plain ACQD does not hold position on air loss; the rod drifts and requires an external rod lock or pilot check valve for fail-safe holding. It uses fixed TPU elastomer bumpers at both ends for deceleration, not adjustable air cushions, so add external shock absorbers for high-energy impacts.
