Airtac ACQD Double Acting Compact Cylinder ACQD80X25SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X25SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm 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 ACQD80X25SB
The AirTAC ACQD80X25SB is a double-acting JIS compact cylinder featuring twin rods that exit from both ends of its riveted C-clip body. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. This symmetry enables perfectly balanced bidirectional cycling without force drop on the retract stroke.
Twin rods provide extended guide length and high torsional resistance, allowing the unit to carry a tool platform directly without needing an external anti-rotation guide. This 80mm bore variant uses a 25mm piston rod with an M22x1.5 male thread (-B) for direct load coupling, a PT3/8 port, and a built-in magnet (-S) compatible with reed or solid-state switches. Deceleration is handled by fixed NBR elastomer bumpers at each end, rather than adjustable air cushions.
Airtac ACQD Double Acting Compact Cylinder ACQD80X25SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X25SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 25 mm |
| Acting type | Double acting, double rod |
| Port size | PT3/8 |
| Rod end thread | M16×2.0 female / M22×1.5 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 (Ø80mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 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 ACQD80X25SB Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer mechanism on packaging machinery, utilizing the equal push and pull forces to maintain consistent cycle timing in both directions.
Twin-Guided Tooling Platform
Mounts a precision stamping head on a press line, leveraging the extended guide length and torsional resistance of the dual rods to prevent deflection without an external guide.
Dual-Station Actuation
Powers a dual-station clamping fixture on an automotive assembly line, using the second rod end to drive a sensor flag for position confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X25SB the Right Cylinder?
At 0.5 MPa, this 80mm bore generates 2267.8 N of equal push and pull force. If your payload is lighter, stepping down to the 63mm bore yields 1401.5 N, whereas upgrading to the 100mm bore provides 3524.8 N for heavier demands. A single-rod ACQ is preferable when asymmetric extension force is acceptable and space is tightly restricted, while a guided TACQ excels if your load requires even greater lateral stability. To configure this SB variant correctly, confirm the 25mm stroke, the M22x1.5 male rod-end thread, the PT3/8 port connection, and the integrated magnet for switch mounting.
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 ACQD80X25SB FAQ
The ACQD80X25SB delivers an equal push and pull force of 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum holding capacity of 463 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The maximum standard stroke available for this 80mm bore is 100mm.
Deceleration is managed by fixed NBR elastomer bumpers at each end of the stroke, not adjustable air cushions; for high-energy impacts, add an external shock absorber. A plain ACQD does not hold its load if air pressure is lost or a valve is centered, so an external rod lock or pilot-operated check valve is required for fail-safe position holding.
