Airtac ACQD Double Acting Compact Cylinder ACQD80X50SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X50SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 50mm 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 ACQD80X50SB
The ACQD80X50SB is a double-acting JIS compact cylinder where a Ø25mm piston rod extends from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, generating 2267.8N at 0.5MPa and 3175N at 0.7MPa of equal push and pull force. This symmetry is ideal for cycles requiring balanced bi-directional thrust up to a 463kgf maximum at 1.0MPa.
Twin rods grant a longer guide length and high torsional resistance, allowing you to carry a tooling platform without adding an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. This 50mm stroke unit includes a male M22x1.5 rod end for direct mounting, NBR fixed bumpers for end-of-stroke deceleration, and a piston magnet compatible with reed or solid-state switches.
Airtac ACQD Double Acting Compact Cylinder ACQD80X50SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X50SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 50 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 ACQD80X50SB Is Used
Symmetric Transfer Pusher
Drives a dual-sided pusher in packaging lines, utilizing the equal push and pull force to shuttle products smoothly in both directions without torque twist.
Twin-Guided Pick & Place
Carries a vertical gripper plate on an electronics assembly machine, relying on the two rods to resist rotation and maintain parallelism during rapid descent.
Dual-Station Actuation
Powers two separate clamping stations simultaneously from one compact body, using the second protruding rod end to drive a secondary mechanism on a machining fixture.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X50SB the Right Cylinder?
Selecting this 80mm bore provides 2267.8N of thrust both ways at 0.5MPa; stepping down to a 63mm bore drops the output to 1401.5N, while moving up to a 100mm bore yields 3524.8N. If your application only requires unidirectional push force and lacks space for a second protruding rod, a single-rod ACQ cylinder is a better fit. For loads demanding extreme lateral precision beyond what the twin rods offer, a guided TACQ module should be considered. Confirm your ordering essentials: this configuration specifies a 50mm stroke, an S magnet, a B male M22x1.5 thread, and PT3/8 ports.
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 ACQD80X50SB 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. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for an 80mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends to absorb shock, which are not adjustable; for high kinetic energy loads, add an external shock absorber. A plain ACQ-type cylinder does not hold its position when air pressure is lost, so a fail-safe setup requires an external rod lock or pilot-operated check valve.
