Airtac ACQD Double Acting Compact Cylinder ACQD80X175SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X175SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 175mm 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 ACQD80X175SB
The ACQD80X175SB is a double-acting JIS compact cylinder featuring twin rods that exit from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa. This 80mm bore configuration includes a male M22x1.5 rod-end thread for direct load coupling and a built-in magnet for position sensing.
Exceeding the 100mm standard stroke limit, this 175mm version is a long-stroke, made-to-order variant. It uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. The dual shafts provide extended guide length and high torsional resistance, enabling a small tool platform to operate smoothly without requiring an external anti-rotation guide.
Airtac ACQD Double Acting Compact Cylinder ACQD80X175SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X175SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 175 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 ACQD80X175SB Is Used
Twin-Guided Machining Pusher
Drives a dual-station clamping fixture on a CNC mill, utilizing the twin rods to prevent torsional deflection under heavy lateral cutting loads.
Symmetric Transfer Unit
Powers a transfer arm in automated assembly machinery, leveraging the equal push and pull forces to maintain perfectly balanced bi-directional cycling.
Dual-End Sorting Diverter
Actuates a sorting gate on a packaging conveyor, using the second protruding rod end to directly mount a mechanical flag for external position confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X175SB the Right Cylinder?
Delivering 2267.8N of symmetric force, this 80mm bore unit sits between the 63mm bore (1401.5N) and the 100mm bore (3524.8N) options. Choose this specific long-stroke 175mm model when extended travel is required beyond the 100mm standard maximum. If your application only needs one-sided actuation, a single-rod ACQ cylinder provides equivalent standard push capacity. When ordering, verify your PT3/8 port interface, the M22x1.5 male rod threading, and confirm the -S magnet and -B male thread options for your sensing and mounting requirements.
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 ACQD80X175SB FAQ
It delivers an equal push and pull force of 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum capacity of 463kgf at 1.0MPa. The push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The 175mm stroke is a long-stroke, made-to-order variant, exceeding the 100mm standard maximum for this 80mm bore.
No, a standard ACQD does not hold position if air is lost; the rod will drift and the fixed NBR elastomer bumper only decelerates the impact near the stroke end. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve. The -S built-in magnet works with reed or electronic solid-state switches for end-of-stroke detection.
