Airtac ACQD Double Acting Compact Cylinder ACQD80X70B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X70B 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 ACQD80X70B
The AirTAC ACQD80X70B is a double-acting JIS compact cylinder engineered with twin rods exiting both ends. Because a piston rod occupies each chamber, the annular area remains identical in both directions, yielding exactly 2267.8N of force at 0.5MPa and 3175N at 0.7MPa for both extension and retraction. This symmetric thrust is ideal for balanced push-pull cycles.
Featuring a robust C-clip and riveted body, this 80mm bore unit resists rotation without needing an external guide. The male M22x1.5 rod-end thread couples directly to tooling, while fixed NBR elastomer bumpers absorb impact energy at stroke limits. Operating at 0.15-1.0MPa with a PT3/8 port, it handles speeds of 30-500mm/s across a -20 to +70C range.
Airtac ACQD Double Acting Compact Cylinder ACQD80X70B Technical Specifications

|---|---|
| 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 ACQD80X70B Is Used
Twin-Guided Pusher
Drives a wide packaging pusher plate on a case erector, relying on the dual rods to prevent yaw and maintain parallel alignment without an external guide rail.
Symmetric Transfer Unit
Powers a pick-and-place transfer bridge in electronics assembly, utilizing the equal push and pull forces to maintain stable dynamics during bidirectional strokes.
Dual-Station Actuation
Actuates a secondary clamp via the rear rod end on a multi-station machining fixture, synchronizing two operations from one compact 80mm body.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X70B the Right Cylinder?
Selecting the ACQD80X70B provides 2267.8N of equal bidirectional thrust at 0.5MPa. If your application requires less force, the 63mm bore generates 1401.5N, whereas stepping up to the 100mm bore yields 3524.8N. This specific configuration includes the male M22x1.5 rod thread and lacks a magnet. If your design needs position sensing, specify the -S option for reed or solid-state switches. Note that a standard ACQD does not hold position upon air loss; integrate an external rod lock or pilot check valve for fail-safe load holding.
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 ACQD80X70B FAQ
The ACQD80X70B 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. Push and pull forces are identical because the twin rods create the same annular piston area in both chambers. The stroke is 70mm, and the maximum standard stroke available for this 80mm bore is 100mm.
This model uses fixed NBR elastomer bumpers at both ends to decelerate the piston, which is not an adjustable air cushion. For high kinetic energy loads, add an external shock absorber. Additionally, this specific configuration ships without a sensor magnet, though the body retains magnetic-switch grooves; order the -S suffix if reed or solid-state position detection is required.
