Airtac ACQD Double Acting Compact Cylinder ACQD80X45SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X45SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 45mm 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 ACQD80X45SB
The AirTAC ACQD80X45SB is a double-acting JIS compact cylinder featuring twin Ø25 mm rods exiting both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding perfectly equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa. This symmetric thrust is ideal for balanced transfer cycles. The integrated -S magnet works seamlessly with reed or solid-state electronic switches via the body grooves.
The dual-rod architecture inherently resists rotation and provides an extended guide length, allowing you to carry a tool platform directly without needing an external anti-rotation guide. Equipped with the -B option, its male M22x1.5 rod ends couple directly to your loads. Deceleration relies on fixed NBR elastomer bumpers at each end rather than adjustable cushions. Note that a standard ACQD cannot hold a load if air pressure drops; achieving fail-safe positioning requires an external pilot-operated check valve or rod lock.
Airtac ACQD Double Acting Compact Cylinder ACQD80X45SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X45SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 45 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 ACQD80X45SB Is Used
Twin-Guided Pusher
Drives a heavy machining fixture on a CNC lathe, using the dual rods to maintain strict parallelism and prevent platform rotation under heavy 3175N loads.
Symmetric Transfer
Powers a parts shuttle in an automotive stamping line, utilizing the identical push and pull forces to maintain consistent cycle times in both directions.
Dual-Station Actuation
Actuates two clamps simultaneously on a multi-station packaging machine, using the second protruding rod end to drive a secondary mechanism or sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X45SB the Right Cylinder?
For sizing context, the 80mm bore yields 2267.8N thrust both ways at 0.5MPa. If you need less force, the 63mm bore provides 1401.5N, while stepping up to the 100mm bore offers 3524.8N at the same pressure. Choose this ACQD80X45SB when your application demands high equal bidirectional force plus resistance to twisting. If you only need unidirectional thrust, a single-rod ACQ80 is more compact. For high kinetic energy impacts, supplement the fixed NBR bumpers with external shock absorbers. This configuration ships with PT3/8 ports, a 45mm stroke, the -S magnet, and -B male M22x1.5 rod threads.
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 ACQD80X45SB FAQ
The ACQD80X45SB delivers an equal push and pull force of 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum holding capacity of 463kgf at 1.0MPa. Push and pull forces are identical because the twin rods create the same annular piston area in both chambers. The standard stroke limit for this 80mm bore is 100mm.
No, a standard ACQD does not hold its load if air pressure drops or the valve is centered. The fixed NBR elastomer bumpers only decelerate the piston near the stroke ends; they do not act as a brake. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
