Airtac ACQD Double Acting Compact Cylinder ACQD80X300SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X300SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 300mm 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 ACQD80X300SB
The AirTAC ACQD80X300SB is a double-acting JIS compact cylinder featuring twin rods extending from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. This symmetry is ideal for applications requiring perfectly balanced bi-directional cycles. The twin rods inherently resist rotation and provide an extended guide length, allowing you to carry a tool platform without needing a separate external anti-rotation guide.
This specific configuration is a long-stroke, made-to-order variant, as the 300 mm travel exceeds the 100 mm standard maximum for this 80 mm bore. It includes the -S magnet for track-mounted reed or solid-state electronic sensing, and the -B male M22x1.5 rod-end thread for direct load coupling. Deceleration is handled by fixed NBR elastomer bumpers at each end rather than adjustable air cushions, so external shock absorbers are recommended for high-energy approaches. Note that a standard ACQD does not hold position upon air loss; a fail-safe hold requires an external rod lock or pilot-operated check valve.
Airtac ACQD Double Acting Compact Cylinder ACQD80X300SB Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 300 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 ACQD80X300SB Is Used
Symmetric Transfer Pusher
Drives a dual-sided pusher on a packaging conveyor line where the equal push/pull force of 3175 N at 0.7 MPa ensures consistent product transfer in both directions without rotational deflection.
Dual-Station Machine Actuator
Actuates a dual-station assembly fixture using the second rod end to drive a sensor flag, verifying tool position while the primary M22x1.5 male rod end handles the main 300 mm work stroke.
Twin-Guided Lift Platform
Raises and lowers a guided lifting table in a materials handling machine, utilizing the twin rods' extended guide length to maintain platform stability over the long 300 mm travel.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X300SB the Right Cylinder?
Selecting this 80 mm bore provides 2267.8 N of force at 0.5 MPa. If your load is lighter, dropping to the 63 mm bore yields 1401.5 N, whereas stepping up to the 100 mm bore provides 3524.8 N for heavier demands. For this 300 mm stroke, the twin-rod design is crucial to prevent sagging and twisting over the long travel. If your application only requires single-sided actuation, a standard single-rod ACQ cylinder might suffice, but the ACQD is necessary when equal force both ways or dual-end actuation is required. Confirm your ordering code includes the SB suffix for the magnet and male M22x1.5 thread, and verify your PT3/8 port connections.
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 ACQD80X300SB FAQ
The ACQD80X300SB delivers an equal push and pull force of 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum force of 463 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. This is a long-stroke variant with a 300 mm stroke (exceeding the 100 mm standard max), and it features a male M22x1.5 rod-end thread.
Deceleration is managed by fixed NBR elastomer bumpers at both ends, which are not adjustable air cushions; for high-speed approaches, external shock absorbers are recommended. Additionally, a plain ACQD does not hold its load when air is lost or the valve is centered, so a fail-safe hold requires an external rod lock or pilot-operated check valve.
