Airtac ACQD Double Acting Compact Cylinder ACQD80X25S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X25S 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 ACQD80X25S
The AirTAC ACQD80X25S is a double-acting JIS compact cylinder where a Ø25mm piston rod protrudes from both ends of the body. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull thrust of 2267.8N at 0.5MPa and 3175N at 0.7MPa. This symmetry is ideal for cycles requiring identical force in both directions.
The twin rods inherently resist rotation and provide a longer guide length, allowing the unit to carry a small tool platform without an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. It uses a fixed NBR elastomer bumper at each end for end-of-stroke deceleration, and the integrated -S piston magnet works with reed or solid-state switches via the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD80X25S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X25S |
|---|---|
| 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 ACQD80X25S Is Used
Symmetric Transfer Pusher
Drives a dual-sided pusher in packaging lines where equal 2267.8N force is required to advance and retract the transfer carriage smoothly.
Twin-Guided Clamp Station
Holds and positions wide workpieces in machining fixtures, using the twin rods to prevent rotation without adding an external guide.
Dual-Station Actuation
Powers a dual-station actuator on an assembly machine, using the second rod end to drive a secondary flag or tooling load.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X25S the Right Cylinder?
At 0.5MPa this 80mm bore delivers 2267.8N both ways; stepping down to a 63mm bore yields 1401.5N, while a 100mm bore provides 3524.8N. Choose the ACQD80X25S when your application needs symmetric thrust and a 25mm stroke within a compact 80mm frame. If your mechanism only requires unidirectional push force, a single-rod ACQ may be more space-efficient. For loads needing precise lateral stability over a longer stroke, a guided TACQ might fit better. Confirm the PT3/8 port, the M16x2.0 female rod-end thread, and the -S magnet option 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 ACQD80X25S FAQ
The push and pull forces are equal at 2267.8N @0.5MPa and 3175N @0.7MPa, with a maximum of 463kgf at 1.0MPa. Because a rod exits both ends, the annular area is identical in each direction, making the thrust symmetric. The maximum standard stroke available for this 80mm bore is 100mm.
A plain ACQD does not hold position when air is lost; the rod drifts and an external rod lock or pilot check valve is required for fail-safe holding. For end-of-stroke shock, it relies on fixed NBR elastomer bumpers, not adjustable air cushions. For high-energy cycles, add an external shock absorber or slow the approach.
