Airtac ACQD Double Acting Compact Cylinder ACQD50X25SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X25SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm 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 ACQD50X25SB
The AirTAC ACQD50X25SB is a double-acting JIS compact cylinder featuring a 50mm bore and 25mm stroke. Because twin Ø20mm rods exit both ends, the annular piston area remains identical in each direction, generating 824.6N at 0.5MPa and 1154.5N at 0.7MPa of equal force whether extending or retracting. This symmetry is ideal for applications requiring perfectly balanced push and pull cycles.
Equipped with a male M18x1.5 rod-end thread, it couples directly to your tooling. The embedded piston magnet (-S) triggers both reed and solid-state switches, while fixed NBR elastomer bumpers absorb end-of-stroke impact without needing adjustment. The PT1/4 port supplies air across a 30-500mm/s speed range.
Airtac ACQD Double Acting Compact Cylinder ACQD50X25SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X25SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 25 mm |
| Acting type | Double acting, double rod |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø50mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 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 ACQD50X25SB Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer carriage on a packaging line where matching extension and retraction forces prevent workpiece skewing.
Dual-Station Actuation
Simultaneously operates two clamps on an electronics assembly fixture using both rod ends to actuate parallel stations.
Twin-Guided Lifter
Raises and lowers a small machining platform without a separate external guide, relying on the rods to resist torsional loads.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X25SB the Right Cylinder?
Select this 50mm bore if your mechanism needs 824.6N of symmetric thrust at 0.5MPa. Stepping down to a 40mm bore yields 527.8N, whereas a 63mm bore provides 1401.5N. This SB configuration includes the magnet and male rod threads; specify female threads if your mounting requires them. If your mechanism only needs single-direction actuation, a standard single-rod ACQ offers a shorter footprint, while a non-rotating TACQ guided cylinder suits heavier lateral loads. Standard strokes for this bore extend up to 100mm.
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 ACQD50X25SB FAQ
It delivers equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum capacity of 168kgf at 1.0MPa. Push equals pull because the twin rods create identical annular areas on both sides. The maximum standard stroke available for a 50mm bore is 100mm.
No, a standard ACQD will drift if air is removed or a valve is centered. The fixed NBR bumpers only decelerate the piston near stroke ends and do not function as brakes. To maintain position during an air loss, you must install an external rod lock or a pilot-operated check valve.
