Airtac ACQD Double Acting Compact Cylinder ACQD80X70S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X70S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 70mm 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 ACQD80X70S
The AirTAC ACQD80X70S is a double-acting JIS compact cylinder featuring twin rods that exit both ends of the riveted body. Because a piston shaft occupies each chamber, the effective annular area remains identical in either direction, yielding equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa. This symmetry is ideal for applications requiring perfectly balanced bidirectional cycles.
The dual-shaft layout inherently resists rotation and provides an extended guide length, allowing you to mount a tool platform directly without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. Equipped with a -S piston magnet compatible with reed or solid-state switches, it uses fixed NBR bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions.
Airtac ACQD Double Acting Compact Cylinder ACQD80X70S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X70S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 70 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 ACQD80X70S Is Used
Twin-Guided Pusher
Mounts a wide format pusher plate directly to both rods on packaging lines, using the inherent anti-rotation support to prevent plate skewing without external guide rails.
Symmetric Transfer Unit
Drives a dual-sided product diverter in material handling, utilizing the equal 2267.8N push and pull forces to ensure identical acceleration and cycle times in both directions.
Dual-Station Actuation
Powers a dual-station clamping fixture on machining centers, using the second protruding rod end to trigger a solid-state sensor flag for position confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X70S the Right Cylinder?
Providing 2267.8N of force both ways, this 80mm bore unit sits between the 63mm bore (1401.5N) and the 100mm bore (3524.8N) models. If your application only needs unidirectional thrust where push exceeds pull, a single-rod ACQ cylinder may suffice. For high lateral loads requiring a fully integrated linear guide, consider a TACQ series cylinder. When ordering, confirm the 70mm stroke, the PT3/8 port, and the default female M16x2.0 rod-end thread.
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 ACQD80X70S FAQ
The cylinder provides equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum holding force of 463kgf at 1.0MPa. Push and pull are equal because the double-rod design creates the same annular area in both chambers. The standard stroke limit for this 80mm bore is 100mm.
The twin rods resist torsion and extend guide length, eliminating the need for an external anti-rotation guide. It uses fixed NBR bumpers at both ends for deceleration, not adjustable air cushions. The -S magnet works with reed or electronic switches fitted into the body grooves to track position.
